Usage of Concrete Hollow Block in Bangladesh

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!

5 Reasons You Should Use Concrete Hollow Blocks

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.

any weather


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.

History of Concrete Hollow Blocks

Our Impact in the History of Hollow Blocks

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. Concrete hollow blocks used for landscaping and interior designs are obviously slightly different in terms of properties than those used to make residences. We can provide all sorts of customization or changes. If you do not want hollow blocks, we also manufacture concrete solid bricks. Both concrete hollow blocks and solid bricks are quality controlled by experts in the field of construction.

The Science Behind Concrete Hollow Blocks

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.

Let Pavement Tiles Glam Up Your Interiors

Although the concept is quite unfamiliar in Bangladesh, in other countries pavement tiles are widely used to create amazing interior concepts that provide a unique, modern, and outdoorsy look to your home. If you are looking to give your interiors a fresh new look, our pavement tiles can be worth every penny. The texture, color, and shape add structure to any interior installation you desire, making your space appear chic! Here are some fantastic ideas for you.


Low-Maintenance Seating Arrangement

Yes, with pavement tiles you can easily create unique seating arrangements, especially on your rooftop, balcony, and terrace. If you have a swimming pool, it would be better to use paving around it because wooden decks require more maintenance. In fact, paving with these tiles creates a durable and hard wearing structure but also increases style! Around the swimming pool or rooftop you can create walkways for a healthy stroll in your daily routine.


Great For Landscaping

A home is incomplete without landscaping and greenery and we know it. That is why we suggest that you use pavement tiles as flooring for your garden or terrace. Choose a color that matches the interior of your home but also goes with the plants. A warmer color would be better-suited in this case. A perfect option for minimalists who want as much space as possible, pair the flooring with simplistic furniture and unique accent pieces that may have bold color palettes. Have fun experimenting! You can also use pavement tiles to create structures that can hold the soil for plants to grow and bask under the sun. 


Monochrome Vibes

When you have too much color going on around your home, toning it down is a wise decision. You can easily do that by installing pavement tiles within your home but choosing only one color. Maybe, an entire wall or part of a wall can be covered with the same-colored pavement tiles. That wall can be covered with your personal decorations or bare if you prefer. The stark contrast with the white of the surrounding walls would certainly upgrade the aesthetics.


Complementary Colors

This idea is for those whose interiors are too bland. Use pavement tiles on your floor with two different colors. It would look great in your kitchen or terrace, but remember to use the colors carefully. Create an outer border with one color and use the other colored-tiles to fill in. Although this is a very simple way of paving the floor, it would look beautiful. Patterns are also a fun way to dress your floor. Choose similarly patterned tiles on the floor and create a border, then choose a different patterned tile to fill the shape in.


Stacking Pavement Tiles

By stacking pavement tiles on top of another you could explore your artistic intentions in various ways. Create various shapes with stacked tiles if you have enough space in your home. If you want to raise the level of a particular floor in a room, then stacking is not a good idea. It is doable with new pavement tiles only, but new pavement tiles stacked on top of older pavement tiles can make the structure wobbly and uneven looking. The colors may not match or the patterns may not fall in place either. 
Pavement tiles can also be used to spice up your parking lots, driveways, footpaths, approach ramps, etc. If you are looking for customizable options, let us know! Our expertise in high quality construction and innovation will help create marvelous structures for you.

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.

Growing Interest in bti Building Products

bti has been a pioneer in the real estate development of Bangladesh. Besides that, to contribute to the construction sector of our country and to ensure a greener environment, bti established bti Building Products which manufactures eco-friendly Concrete Hollow Blocks, Concrete Bricks, Pavement Tiles and Unipavers. As our government has taken initiative to make such environment-friendly building materials mandatory by 2025, developers are now showing more interest in our products.


Why Developers Say Our Products Are of High Quality:

Exceptional Quality of Concrete Block and Concrete Brick

Our products are superior in quality with multiple benefits. Being hollow inside, Concrete Hollow Block does not only make a building earthquake-resistant, but also soundproof. It is a natural heat absorbent and ensures heat protection, so it can be the right choice for creating your rooftop. It is salinity and damp-proof, and so remains unaffected by weather conditions. Being machine-made, Concrete Block is consistent in finish, and so easy to install somewhere. It can withstand high strengths as it is made of cement, coarse sand, fine sand, pea gravel and stone dust. Being cost-effective, highly durable and aesthetically appealing, this block is used for architectural decoration purposes, internal partition walls, external boundary walls and rooftop.

Concrete Brick also has most of the qualities of Concrete Hollow Block except the hollowness, but it also has versatile applications. This brick is the same in size and cost as traditional red clay brick, but is highly durable in comparison.


Outstanding Quality of Pavement Tile and Unipaver

Being strong (high PSI) and highly durable, our Pavement Tile can withstand huge loads, and so it can be used for making entryway, walkway, driveway, parking lot, sidewalk, basement and rooftop of both residential and commercial projects. This tile is also excellent for making industrial yards. Depending on your usage purpose you can also customize the PSI (strength) of the Pavement Tiles. We have four colours of Pavement Tiles which are homogeneous in shape for easy installation and maintenance. The natural earthy tone of the tiles can make your home walkways appear more classy. For attractive floor finish and adding elegance to your tracks, Pavement Tiles can be very effective.

The high strength and durability of Unipaver made it popular as a flooring material which is used in footpaths, walkways, pavements, driveways, factory yards and garden landscaping. You can choose out of these five colours- Red, Yellow, Blue, Royal Blue and Grey. It also comes in a range of sizes. Being machine-made, our Unipaver is environment-friendly, cost-effective, accurate in dimensions and convenient for usage.
