building products

The real estate industry of Bangladesh is largely dependent on clay bricks for a variety of reasons. However, these bricks not only harm the environment but also increase the overall cost of construction. Planned urbanization, sustainable construction, and a safe environment now call for alternative building materials. By choosing eco-friendly building products, we can prevent environmental hazards and also save construction costs at the same time. Among the innovative building materials used worldwide, Concrete Hollow Blocks are considered superior to other conventional materials such as burnt clay bricks. Our approach to green construction does not limit to hollow blocks only. Over time we have introduced several other eco-friendly products such as Concrete Solid Brick, Unipavers, and Pavement Tiles which are undoubtedly great construction solutions.  

Concrete Hollow Block

Unlike the traditional red bricks, hollow blocks do not need to be burnt; they are made from automated processes which means they cause no harm to the environment and come out with smooth finishing. The hollow blocks of bti Building Products are fireproof, damp-proof, earthquake-resistant, and most importantly eco-friendly. On the other hand, the soil used in the conventional method of making bricks is collected from the surface of agricultural land. As a result, the amount of our agricultural land is decreasing day by day which is threatening our food security. A study found that on average, about 600 acres of agricultural land is being lost every day which is more than 1% of the total cultivable lands. This means Concrete Hollow Blocks are a great alternative to clay bricks.  Above all, the government has announced Concrete Hollow Blocks to be made mandatory by 2025 whereas we have been producing and using our blocks since 2016. Thus, when it comes to innovation in construction, we are always one step ahead.

Concrete Solid Brick

Just like Concrete Hollow Blocks, solid bricks are also an innovation in construction. They also have almost the same properties just as hollow blocks. They come in different sizes and uniform shapes. Concrete Bricks are made with powdered portland cement, concrete, water, sand, and gravel. Being made of concrete, solid bricks are strong and increase the durability of construction. Unlike the traditional red bricks, it has less salt which makes its salinity negligible. Our Concrete Bricks are far more durable, cost-effective, and environmentally friendly. This makes any construction long-lasting and sustainable as it does not require the use of clay bricks. The amount of noise pollution and heat transfer is comparatively 40% less, and the solid bricks are able to adapt to any kind of weather change.

Pavement Tiles

Pavement tiles have also paved the way for green construction. When you are done with construction, you may need to make sidewalks, entryways, driveways, or more. Pavement Tiles are highly suitable for making driveways, walkways, entryways, rooftops etc. The Pavement Tiles of bti Building Products are made in automated machines using state-of-the-art technology without any involvement of manual labor. Moreover, their easy installation process is ideal for gardening and landscaping. They are not just kind to the environment but also add elegance to your tracks.  

Unipavers

Unipavers are primarily used as flooring materials. Our Unipavers are made of cement, coarse sand, fine sand, pea gravel, and stone dust. They are locally sourced and machine-made. This is how we utilize recycled materials so that they do not cause any harm to the environment. They are getting seemingly popular because they are easy to install and highly durable. Hence, they are widely used in footpaths, walkways, pavements, driveways, factory yards, and garden landscaping. Unlike other flooring materials, they can be customized according to your preference, so you can choose the size, shape, and colors of your choice.  

An exemplary approach to green construction

We always believe in green construction and thus we incorporate greenery in each of our projects. That’s why we implement earthquake-resistant designs with fire safety measures. Because we understand that a catastrophe does not just harm one individual only but also the environment and an entire community. bti Building Products has been using eco-friendly building materials for ensuring green construction from the very beginning. Moreover, we use solar panels in all our projects to reduce energy consumption. Through nature-integrated designs, be it on rooftops, entryways, gardens, or wherever possible, we make sure that every home is sustainably made.   

We have only one earth, so it is our solemn duty to protect the only home we have by incorporating and using eco-friendly building materials as much as possible. This is how we can reduce the harmful emission of carbon to save the environment before it’s too late.

Our happiness largely depends on how safe we feel at home. Choosing an eco-friendly building material to build your dream home not only saves the environment but also saves your overall construction costs. Among all the innovative building materials used worldwide, Concrete Hollow Blocks are considered to be superior to other conventional materials such as burnt clay bricks. Their excellent fire-resistant features help to keep the blaze at bay. They do not emit harmful chemicals, unlike the traditional red bricks. There are other reasons why this particular product tops all the other building materials.

One of the main reasons that the hollow blocks do not catch fire is the reason for the inflammable materials they are made of. When exposed to high temperatures, they do not even discharge any baleful chemicals. Flammable materials, on the other hand, combine oxygen that facilitates the flame to cause and spread the fire easily. The raw materials used in hollow blocks are cement, stone dust, coarse and fine sands, along with pea gravel. They consume less energy and no harmful gases are emitted which makes them non-flammable and ensures the safety of buildings. 

Another major factor of the hollow block being fireproof is it is low in thermal conductivity. This implies that even if a building catches fire it takes less time to spread in the entire building. Its load-bearing capacity and structural features do not let it catch fire easily even if any building is set on fire, the non-combustible materials protect it from spreading fire. Nevertheless, not all kinds of concrete blocks are fireproof. Hollow blocks consist of cement and other aggregated materials that are needed to protect any structure from catching fire.  

Above all, the presence of concrete in the hollow block does not cause any chemical reaction. Concrete can withstand fire for up to four hours. Although it depends on the other aspects of our homes such as furniture, fixtures, fittings, etc. Unlike wood and steel, concrete takes less time to spread fumes. Of course, only the presence of concrete does not ensure that a building will not catch fire. It just follows a concrete structure to spread the flame from one area to another contrary to a wooden structure.  

To sum it up, hollow blocks prove to be a great choice for construction in minimizing the danger of fire. Now that the myth is busted about whether Concrete Hollow Blocks are fireproof or not, you can undoubtedly choose this material for building a safe haven for your family.

Ever since modern construction started in Bangladesh, people mostly relied on using traditional red bricks for construction. The reasons are obvious. Producing red bricks requires cheap labor. Its raw materials are readily available. However, with increased reports of global warming and environmental degradation already adversely affecting Bangladesh, experts are now considering alternatives. Since producing red bricks is very harmful for the environment, environmentally conscious developers and manufacturing industries have moved on to a far better choice – concrete hollow blocks. 

Our Story

Concrete hollow blocks are very popular in other countries for masonry, constructing boundaries, floodgates, and a wide range of other functions. Bangladesh was largely unfamiliar with it. In 2011, bti Building Products started manufacturing concrete hollow blocks from its factory in Dhamrai. It was an innovative move, since most developers were still using red bricks. We recognized the genius behind the production of concrete hollow blocks and its potential to change the construction scenario in our country forever. 

Why Choose Concrete Hollow Blocks

Concrete hollow blocks are machine-made, which means every edge will be seamless, smooth, with an overall perfect finishing. Since there is no physical labor or time-consuming manual work involved in production, it saves both time and costs. Red bricks require extreme high temperatures and conditions for manufacturing, but concrete hollow blocks can be easily made in normal conditions, which again saves time and costs, and also prevents them from harming the environment. Its raw materials are readily available and sustainable, which means you will not have to worry about raw materials supply. The production process requires much less water and cement compared to red bricks. Since concrete hollow blocks are cheaper and quicker to produce, your construction time is also reduced. These are great advantages, which encouraged many developers to use the blocks in their buildings. 

One red brick unit is equivalent to five units of concrete hollow blocks. This aspect also helps in ensuring faster, cost-effective construction. The mineral composition of red bricks can deteriorate with time, and water from the atmosphere can add to the damage.  Concrete hollow blocks are weather-resistant and soundproof, something that red bricks are not. Homes made with these blocks remain warm in the winters and cool during the summers as a result. With time, a building made of red bricks can lose its durability and strength, but a building made of concrete hollow blocks becomes stronger and tougher with time, making it more resistant in the wake of natural calamities. When weights are compared, you will realize concrete hollow blocks are way lighter than red bricks, making its use even more convenient.

A New Generation of Building Blocks

The concrete hollow block manufacturing industry is now worth a staggering 90 billion taka. The Government has declared that all buildings should be made of concrete hollow blocks, and by three years it will become mandatory for construction firms to use these blocks only. The move was made to ensure prevention of the environmental damage caused by red brick kilns. The demand is soaring to the point that now many kiln owners are moving to manufacture concrete hollow blocks instead of red bricks. A massive challenge is to familiarize non-urban people with hollow blocks, who are still not aware of the damage caused by traditional red bricks. Even if they understand the benefits of hollow blocks, they would try to buy from small companies who produce cheap hollow blocks, but of low-quality. To avoid such situations, it is always best to procure blocks from a reliable name. 

If you are an individual hoping to build your dream home, or a developer all set to embark on a new construction project, ask bti Building Products for concrete hollow blocks. We have been producing it since 2011 and have been leading the industry since then, with rigorous testing conducted by engineering experts and use of top-notch raw materials. Our high-quality concrete hollow blocks are sure to impress you!

In a densely populated country like Bangladesh, it is crucial to keep pace with the ever-growing housing needs of every citizen. Consequently, the dependence on domestic construction materials is also on the rise and one of them is Concrete Hollow Blocks. As a result, the prices of building materials are soaring but the price of concrete hollow blocks in that sense is quite moderate. This superb building material brings about a myriad of benefits for construction which is why it is seemingly getting more popular day by day. Hollow blocks do not require any gas, burning coal, fertile soil, and do not emit carbon dioxide in any way. In short, it is completely an environmentally friendly building material. Not only that, this product offers various advantages, unlike the traditional red bricks. Let us explore more about its benefits.

Strength and Safety Like None Other

Concrete hollow blocks are widely used because of their unbeatable durability. The compressive strength depends on the composition of the blocks. They are made with high pressure and vibration which make them durable to last for decades. Moreover, their ability to withstand heavy loads and their lightweight nature reduce the overall weight of the building. The stable foundation and the ability to withstand heavy loads provide great safety from earthquake havoc and other natural disasters.

Superior Quality

The housing sector is rapidly getting dependent on the hollow blocks because of their superb quality. They are made in automatic machines with cement, crushed stone, soil, stone dust, etc. Whereas terracotta bricks are made only with clay. As a result, the durability of terracotta bricks decreases day by day. They are also fragile and susceptible to damage. On the other hand, the stability of the hollow blocks does not deteriorate over time. Consequently, hollow blocks when used in walls do not get weakened or stained easily.

Cost-effective Construction

The biggest aspect of using hollow blocks is that the construction cost is comparatively less than the traditional red brick. Cement-sand is less required in the masonry of concrete block walls. Additionally, it reduces the weight of the building and the construction also takes less time than usual. One block is capable of replacing 5 red bricks which ultimately reduces the construction cost. Being made of concrete makes it even stronger and increases the durability of construction with the passage of time. Hollow blocks come in uniform sizes and the consistent finish makes them easy to install and speeds up construction. Another positive aspect is that walls made of blocks can be finished with paint which reduces the overall cost of interior decoration.

Adaptable to Any Weather

The hollow blocks are not only durable but also adaptable to any kind of weather change. They are highly capable of withstanding any form of weather be it sunny or stormy. The houses built with hollow blocks remain cold in summer and hot during winter. Concrete Hollow Blocks from bti building products are made with high-quality raw materials such as fine sand, Sylhet sand, pea gravel, coarse, etc. These materials make the blocks remain unaffected by natural disasters. So undoubtedly, hollow blocks are an ideal choice for ensuring a solid foundation for any construction. Another important factor of hollow blocks is that their hollow nature prevents sound and heat thus making your walls soundproof and damp proof. In contrast, walls made with red bricks get easily moistened and damaged especially during monsoons.

Environment-friendly

Unlike the traditional red bricks, hollow blocks do not need to be burnt; they are made by automatic machines which means they cause no harm to the environment. On the other hand, fertile soil is needed to make red bricks. As a result, agricultural land is being used in all the traditional and modern fuel-saving brick kilns, and automatic brick factories in Bangladesh. Furthermore, wood is being used as fuel in almost all traditional brick kilns. Imported coal, even gas, is being used as fuel. Thus, the use of fertile soil is wasting agricultural land which is why using agricultural land for brick production is now banned in China and India. However, according to a study by the House Building Research Institute (HBRI), “The cost of building construction could be brought down by 25 percent with the use of eco-friendly materials like hollow blocks, instead of traditional bricks.” The government has already announced to completely ban the use of traditional red bricks from 2025 to save the environment. So, from now on, it is better if we adopt to use hollow blocks for any construction project.

It is crystal clear that the benefits of hollow blocks are numerous which is why their popularity is also increasing very rapidly. However, in terms of low-cost construction, high-quality finish, earthquake resistance, and most importantly ensuring a safe and solid foundation for your family, there is no alternative to using concrete hollow blocks. So, if you are worried about your upcoming construction then concrete hollow blocks from bti building products will undoubtedly be an ideal option for you.

The typical scenario in Bangladesh for decades has been the use of traditional red bricks during construction. Normally one would believe that they have been around for a very long time, but the truth is concrete hollow blocks have also been used since ancient times. In fact, concrete mortar was first used by the Romans around 200 B.C to bind already shaped stones into buildings. Since then, concrete hollow blocks have come a long way. The blocks also made its way in Bangladesh, and bti Building Products was a pioneer to bring them to the forefront of building materials since 2010.

How it Started

The Romans were famous for using concrete mortar. In Naples there were formations created using small precast blocks. Much of that technology was lost after the fall of the Roman Empire. It was only in 1890 that the revolution started, when Harmon S. Palmer of the United States patented the hollow concrete block that he designed himself. His block was so heavy it had to be lifted around with a crane, but nevertheless, it became incredibly popular. Soon, as many as 1500 companies started using concrete hollow blocks for construction. The first home made entirely of concrete hollow blocks was built in 1837 in Staten Island, New York. The reason there was a sudden boom in its use was because the materials required to create it were available in abundance. The raw materials are easily available even now. Back then all blocks were made by hand. On an average, a person could create 10 blocks per hour. 

How it is Made

A concrete hollow block is precast, meaning it is already shaped into a block and hardened before use in construction. The sides of the block may be seamless and smooth or etched with design. The block can have one or two hollow cavities within, and can be stacked atop each other with mortar. This way you can build the wall according to the desired length and height. Although it was previously made by hand, it is now made with highly efficient machines that can produce 2000 blocks per hour. All our concrete hollow blocks are precast in our Dhamrai factory, and then used in our construction. Raw materials include use of cement, water, sand, and gravel in different ratios, but further components can also be added. For example, cinder blocks are made by also adding volcanic cinder or granulated coal into the mixture. Lightweight blocks are made by adding clay, shale, or slate instead of sand. This means concrete hollow blocks can be easily modified and serve different purposes based on their different properties. Each type of block would have a certain set of properties. 

Various chemicals may also be used to alter the properties, such as modifying curing time and compressive strength. Pigments can be added for color and glaze can be added for decorative effects.

Why Use Our Concrete Hollow Blocks

bti Building Products uses lightweight hollow concrete blocks for construction purposes. It is not only a more eco-friendly approach to construction, but it also reduces time and costs. On top of that, even the government has amped up the use of concrete hollow blocks. They are also set to become mandatory in construction by 2025! Since we have led the real estate industry for decades, it only made sense to mass produce concrete hollow blocks for everyone who wants to reap its benefits. Our blocks are designed in such a way that it provides a great level of advantages. Our blocks can form lightweight buildings, which means less prone to earthquakes, are incredibly resistant to water degradation and weather issues. These blocks are vermin proof and fire proof as well, and salinity proof too. Traditional red bricks lack these properties, which is why our concrete hollow blocks are also used to create garages, factories, warehouses, offices, etc. Their adaptability and flexibility to modification allows their use in landscaping and interior design for a more urban, modernistic look in a building. 

When manufacturing, we at bti Building Products always take into consideration the client’s requirements. So any additives to be added and any modifications are done with proper consultation.

However, these magic blocks are not just great for construction, but also for adding some spark to your home environment. These blocks are useful in too many ways, so we have found a few creative methods that you can easily apply while building or renovating your home!

For The Love of Plants

Are you someone who wants to stay connected to nature? Looking for your own green corner? Concrete hollow blocks can easily serve your gardening skills. They can be loyal plant carriers by safely containing soil and other nutrients for your seedlings to grow into full-blown plants. The best part is that you can build the blocks into any structure. Whether it is a tower or a pyramid full of blocks, you can get creative and plant anything accordingly. You can also define the amount of space that your mini garden will take over in the room or terrace. Succulents and vegetables and even flowering plants can be grown with hollow block planters.

Smart Repurposing

You can join the trend of upcycling items in your home with the twist of concrete hollow blocks. Whether it is extra seating or a DIY side table, you can easily use these blocks to create these furniture at a shockingly low price. Such furniture would ideally look great in terraces and balconies, but they can also be used in bedrooms to give a more rustic feel. Just stack a few blocks together and then add a hard plank of wood on top, sprinkle some pillows and cover with a brightly colored cloth and you have a neat little seating arrangement. A nightstand or a side table would be made the same way but would require less number of blocks minus the pillows. Maybe add a little lamp, and a few books?

DIY Outdoor Bar

Visiting night clubs or parties through the traffic is painful nowadays, and with the pandemic going on it also feels a little restricting to have some fun while social distancing rules are still applicable. Instead, why not create your own mini bar with concrete hollow blocks stacked on top of another? You can paint the blocks with multiple colors that suit your interiors and then place a console table on top to complete the look. Then use the hollow part of each block to place drinks and some decorative pieces.

Concrete Risers

Instead of store-bought risers for your furniture, simply use concrete hollow blocks of the same height underneath each piece of furniture. The best part is that you can use these hollow block risers to stash secret items and even shoes to save space. The blocks will also help add a rustic touch to your interiors.

The 6.1 magnitude November earthquake in Bangladesh that jolted citizens in Dhaka and Chattogram awake in the wee morning hours has got everyone panicking recently. Reports of buildings tilting were observed, and experts have predicted that at any given moment an earthquake of a bigger scale can shake the country. In fact, a study by CUET noted that 78% of buildings in Chattogram are at risk if that happens. So the question remains – as responsible citizens in an unplanned urban scenario, have we ensured solid construction for our own safety? Apart from having excellent construction quality and skills, it is also important to use high-quality raw materials, one of which is our hollow concrete blocks. 

Eco-friendly Much?

Concrete blocks are manufactured differently and also involve different raw materials. They involve a mixture of cement, sand, and aggregate typically using limestone, all combined with water. Red bricks are made from clay, aggregate, and water in certain compositions. While clay bricks are cured by the vitrification process in temperatures exceeding 2000°C, concrete blocks are cured by a chemical reaction between cement and water that requires a temperature around 150°C, which is a lot more environmentally-friendly and cost-effective in terms of maintenance. Concrete blocks also consist of fly ash, a byproduct of many manufacturing processes, thus effectively helping to recycle industrial waste. The manufacture of red bricks on the other hand leave a significant carbon footprint and harmful impact on the environment.

Since it saves construction time and requires less water and mortar, we can say that concrete hollow blocks are flag bearers of environmental consciousness in terms of reducing, recycling and reusing materials in an efficient manner.

How Are Its Properties Different Than Red Bricks?

These blocks have many desirable properties. After manufacturing it loses moisture and shrinks in size, becoming more waterproof, while red bricks expand in size over time with absorption of moisture. Thus, it can withstand humid or rainy weather easily. In a country like Bangladesh where rainfall is common, these blocks have become a popular choice in construction for this reason. 

Concrete blocks are lightweight but tougher due to higher compressive strength. The most amazing part is that concrete blocks gain strength over time unlike red bricks. This means any building made of concrete hollow blocks will have significant earthquake and weather resistance, which is especially good news for those intending to construct high-rises or buildings that may be more prone to external pressure. 

The simplistic design allows uniformity and ease when applied during construction. So if you are constructing using hollow blocks, chances are that you will be able to finish the work faster or right on time. The hollowness creates lower density, which  allows better heat management with change of seasons and cancels out noise. 

Bti’s concrete blocks are manufactured with the intention to build safe and strong foundations that will last a lifetime. At a reasonable price your property will be ensured durability and incredible toughness. Whether you are a developer or someone willing to construct your own property yourself, you will not have to look any further when you opt for high-quality building products backed by the excellence of bti. If you do not prefer hollow blocks, we have concrete solid bricks in store as well. You can get more details simply by giving us a call.

Individual and real estate developers are now showing interest in buying our Concrete Hollow Blocks and Concrete Bricks, as we offer many benefits to make construction safe and long lasting.

To eradicate pollution for the sake of public health and environment, eco-friendly building
materials are imperative. bti came forward with the initiative to care for the environment by
establishing the world-class bti Building Products factory in Dhamrai. The state-of-the-art
technology and supporting architecture of this factory are used to manufacture eco-friendly
building products, namely Concrete Hollow Block, Concrete Brick, Pavement Tile and
Unipaver. Landowners, developers and clients can ensure the highest quality of construction of
their residential and commercial projects with these building products. In this blog, you will find
out the innovative approach used by the factory to create quality building products.

The Quality We Maintain
The production processes of Concrete Hollow Blocks, Concrete Bricks, Pavement Tiles, and
Unipavers are all environment-friendly, and they incorporate recycling as an essential step. The
factory is spread across 5 ½ bigha land. Various respected dignitaries, including the Bangladesh
Army visited our factory to see how we maintain high quality throughout the manufacturing
process. Our quality control lab ensures that every piece produced is perfect for usage. After
production our blocks and bricks go through the following BUET-approved tests- Compressive
Strength Test, Water Absorption Test and Salinity Test. Only after passing these tests
successfully, our building products get approval to be sold in the market.

The Building Materials We Use
Concrete Hollow Blocks and Concrete Bricks are made of stone chips, coarse sand, fine sand,
local sand, stone dust, pea gravel, and cement. Our Pavement Tiles and Unipavers are also made
of such materials. Being made of these substances, our building products are highly durable,
tough, and can withstand immense load. Our building products are salinity and heat-resistant
and prevent dampening. Combined with earthquake-resistant technology, they create formidable
building structures that can stand the test of time.

Modern Machinery and System We Use
In our factory eco-friendly products are made through machine-automation without any
environmental pollution. We have feeding unit, mixing unit, hopper, cement silo, conveyor belt,
palette store, hydraulic press unit, and block stacking yard in our Dhamrai factory. The full
processing system is monitored by our experts. As our products are machine made, they are
consistent in finish, accurate in size and weight, and easy for installation in your residential and
commercial projects. Besides these benefits, you are also getting an extra advantage of
customizing the products after your choice if you buy from us.

Assistance and After-Sell Service
Construction work with our building products requires you to undertake processes such as
chipping, grouting, mortar laying, block work, pie chip casting, wire mesh setting, painting, etc.
Arranging technicians, workers and labourers for the whole procedure needs experts and trained
people. bti Building Products not only manufactures and sells products but also offers both
technical support and training to the customers. We send our expert architects and workers to
support and train your workers in using our modern eco-friendly products. Therefore, you can
avail construction products, assistance and services from bti Building Products without any
further difficulty in arranging for your construction.

Red clay bricks and such other traditional building materials have proved to be fragile,
inconsistent in finish and not highly durable. As a result, buildings made of them are prone to
earthquakes and weariness over time. In such a context, out of social responsibility and
willingness to contribute to the construction sector, bti established bti Building Products. Since
its inception, our factory in Dhamrai has been manufacturing eco-friendly high-quality
construction materials for providing you the best building products and related services for your
residential and commercial projects. We have been successfully manufacturing our products
since 2014 with an aim to reduce our carbon footprint, in line with the recent Government rules
of making concrete hollow bricks and blocks mandatory by 2025. We do believe the future of
construction in Bangladesh lies with bti Building Products in this regard.
