A blinding concrete plate is a base layer that is cast into a footing trench before installing any reinforcement for foundations. It has a minimum thickness of about 2 inches.
Blinding concrete plates are laid to level the surface of a footing trench. These concrete plates also serve as under layers for ceramic tiling and flooring purposes. Compared with structural concrete, blinding concrete can withstand much lower pressure and is therefore used for lighter duty construction.
Blinding is used to create a strong level surface for either of the two purposes: an underlying mass fill and a concrete slab. Steel mats are used as reinforcements either on the entire blinding concrete layer or only on those areas that have highest static loads.
