What Is Brick Bat Coba Waterproofing?

Hi, I had brick bat coba waterproofing done for my terrace. I hired a painter for the job, and before the process, I had asked him what is brick bat coba. He told me that brick bat coba is a method of waterproofing in which a layer of broken pieces of bricks is used over a flat concrete roof. Following that, a cement-sand mortar mix is used to fill the gaps between the bricks.

The painter also told me about the advantages and disadvantages of this process. Here are the advantages and disadvantages of Brick Coba waterproofing.

Advantages of Brick Bat Coba Waterproofing

According to the painter

• This is a cost-effective waterproofing process that can be completed in a short time. 

• The materials required are Masonry brick wastages.

• It doesn’t require highly skilled manpower as well. 

Disadvantages of Brick Bat Coba Waterproofing

The painter told me that

• This process increases the dead weight of the structure as it uses bricks. 

• If any cracks are found on the surface, then immediate rectification is required. If not done immediately, then there could be a lot of issues in the future. 

And that’s what the painter told me when I asked him what is brick bat coba waterproofing. Despite the disadvantages, I still felt that its advantages were overwhelming and thus decided to get it done. 

Brick bat waterproofing is a good choice for flat RCC roofs since it provides waterproofing and insulation for thermal comfort while also preventing water loss.

It comprises laying brickbats on a flat RCC roof and grouting them with waterproofing solution with a slope to drain surface water, and it is one of the earliest waterproofing procedures.

If the slab top has already been coated, remove the coating and clean the surface with a hard wire brush before washing with water. After understanding what is brick bat coba waterproofing let us focus on:

Some important materials are required for making brick bat Coba, which are mixed together and then applied to the cleaned terrace floor. 

• Tapecrete

• Cico 

• Fibermesh net

• Cement 

• Sand 

• Bricks

It will be advantageous if the slab has already been roughed up. This will only happen when the slab is cast; it will be roughed out first, and then there will be no need to rough it out again. There should be no loose materials on the slab, and it should be well cleaned and neat.

I hope this answer provided a certain amount of clarity regarding brick bat waterproofing.
