Introduction of Hollow Bricks:
- Bricks are one of the most essential and commonly used Building units in the construction world after cement.
- Traditional bricks are widely used in the construction of Buildings. Nowadays there are many innovations and research is going on in the construction industry to develop innovative and cost-effective Construction materials which have more advantageous and economical as compared to traditional building materials.
- In this article, we will see about hollow bricks and it’s Advantages and Disadvantages.
- The Hollow brick is the new innovative building unit which is becoming popular of its various uses. Hollow bricks Construction is eco-friendly in nature and does not create any pollution in nature.
What Are Hollow Bricks?
- Hollow bricks are also known as porotherm bricks. It is a new age brick which is widely gaining popularity in the construction industry.
- Hollow bricks are perforated either horizontally or vertically. The overall performance of the hollow bricks is very good as compared to the traditional bricks.
- Hollow bricks are very easy to handle on-site and help in faster construction. They are environment friendly and absorb less amount of water as compared to the traditional clay bricks.
- Because of its low Absorption of water, there are very few chances of efflorescence on the hollow brick walls. Hollow bricks help to improve the aesthetical beauty of the structure and gives a better view and surface as compared to the Construction of traditional bricks.
- Hollow bricks Construction is rated by the Green Building Council of India. Hollow bricks are eco-friendly Construction material which is manufactured by recycled waste and materials such as coal ash, rice husk, and fly ash.
- The Hollow bricks are the innovative construction material which is a substitute to the traditional bricks which are used in the construction.
- The main function of the hollow bricks is to reduce the dead load of the Structure because the hollow bricks are the most lightweight building materials. The holes or the pores present in the bricks help to reduce the weight of the brick and make it lightweight.
- The Hollow brick wall is mostly used as the partition in the buildings but it is also used as the load-bearing walls as per the Compressive strength of the hollow brick.
- The hollow bricks have the thermal insulation property which helps to reduce the cooling as well as heating effects as per the weather conditions.
- The hollow space of the poles which are present in the hollow bricks is used to pass the plumbing as well as electrical wiring which is not possible in the traditional bricks.
- The thermal insulation property of the hollow bricks helps to save resources and costs. It is because of the air present in the holes of the hollow bricks which helps the hollow bricks wall to keep the internal environment of the building cool in the summer whereas warm in winter.
- The Thermal insulation of the hollow bricks is more as compared to the traditional bricks. The bonding capacity of the hollow bricks is very high because the concrete can be filled in the pores of hollow bricks which helps to improve its strength.
- Hollow bricks provide uniform quality, faster construction, and less labour involvement and hence prove economical and cost-effective Construction material.
Advantage of Hollow Bricks:
They are various advantages of hollow bricks which are as follows.
- Hollow bricks are an eco-friendly construction material which does not lead to pollution.
- The hollow bricks help to reduce the cooling and heating effect as per the weather requirements due to its thermal insulation property.
- The hollow bricks help to conserve energy and resources.
- The hollow bricks provide good sound insulation property.
- Hollow bricks have good compressive strength so that it is used for the construction of the load-bearing walls.
- One of the best advantages of hollow brick construction that it is also used to pass the electrical as well as plumbing fixtures through its Hollow space.
- Hollow bricks are cost-effective and required very less maintenance.
- Hollow bricks have more fire resistance as compared to solid bricks.
Disadvantage of Hollow Bricks:
There are also some disadvantages of the hollow bricks which are as follows.
- The load-bearing capacity of hollow bricks is a little low because of the pores as compared to the solid Bricks.
- One of the disadvantages of Hollow bricks is that it cannot be used in the construction of large structures and foundations of buildings.
- The hollow bricks are not suitable in the areas where the water table is high because the bricks cannot resist it because of its low density.
Sizes of Bricks Blocks-
The hollow bricks blocks are available in various sizes in the market but the commonly used sizes of bricks blocks are as follows
- 400 mm x 200 mm x 100 mm
- 400 mm x 200 mm x 150 mm
- 400 mm x 200 mm x 200 mm
- 400 mm x 200 mm x 300 mm
How to Make Hollow Bricks?
- The hollow bricks are constructed with the help of clay. The hollow bricks have a plane surface such that it requires less amount of material for plastering.
- Hollow bricks have less density as compared to solid bricks because of the presence of holes in it which makes it less dense and lightweight.
- The hollow bricks are manufactured at site. First of all the raw materials are collected which is required for the manufacturing of the hollow bricks.
- The proportioning of the raw materials is done as per the requirement and it is properly mixed. If the hollow brick is made from cement then the material is mixed in the rotator.
- After proper mixing, the material is filled in the moulds of the hollow bricks and compacted properly such that there should not be any voids remain in it.
- Then the hollow bricks are kept in the water tank for 7 days for the purpose of curing. Now the hollow bricks are ready to use for the construction.
Hollow Bricks-
These Clay Hollow Bricks can be used for both load-bearing and Non-load bearing construction. Moreover, the offered Clay Hollow Bricks are highly durable in nature and extensively used in various suitable applications.
Advantages of Hollow Bricks:
They keep the interiors cool in summer and warm in winter especially the ‘clay hollow bricks‘. They also provide more sound insulation as compared to solid bricks. Better usage and strength- Hollow bricks display good compressive strength making them suitable to install heavy wall compartments, cabinets, geysers, etc.

Disadvantages of Hollow Bricks:
- Hollow blocks have poor bearing capacity because the total mass of wall decoration materials is reduced, the load-bearing capacity is also reduced.
- It is very dangerous to hang heavy objects on such walls.
Hollow Bricks Wall-
Walls constructed with an air space within the masonry termed hollow or cavity walls, are commonly used in modern. building construction as a means of protecting the wall against. rain passing through it, and enhancing the thermal insulation of. the wall.
Hollow Bricks Construction-
Hollow bricks are bricks that have several holes in it. These bricks can be used to build both load-bearing as well as non-load-bearing walls. These bricks have been proven to be much more beneficial than traditional bricks. Hollow bricks are fire resistant and at the same time much safer than ordinary bricks.
Size of Bricks Blocks.
Blocks are formed in steel molds and since the material is relatively stable, the size of the individual units can be controlled to within small tolerances. Bricks are generally made to a traditional size – 230mm long, 110mm wide and 76mm high.
