Brick Bat Coba is a traditional waterproofing method widely used in construction to provide thermal insulation and weatherproofing for flat roofs. The term "Brick Bat" refers to broken pieces of traditional clay bricks, which are embedded in a mortar layer to create a protective and heat-resistant surface. This method is particularly popular in regions with hot climates, where the insulation properties of Brick Bat Coba help in reducing heat absorption by the building.

The process involves laying a layer of broken bricks over a prepared concrete slab, with the gaps filled using a mortar mix. The bricks create an undulating surface, allowing water to flow easily towards drainage points and preventing the formation of stagnant water, which could otherwise lead to leaks and structural issues. The mortar mix provides a strong bond and secures the bricks in place while also serving as a waterproofing layer.

Apart from its waterproofing capabilities, Brick Bat Coba is valued for its cost-effectiveness and relatively simple application. The broken bricks used in this method are readily available and can be recycled from construction waste. The undulating surface also adds a textured finish, contributing to the overall aesthetics of the roof.
