What's the name of the cement platform around the building?

There is no specific name for this. We usually call it waterproof road to prevent rain from soaking the foundation. It is generally 60 cm wide.

Refers to the protective layer around the house, which is used to protect the foundation of the wall and disperse rainwater from the foot of the wall. It is generally about 800 mm wide. There are brick pavement aproll, cast-in-place fine stone concrete and concrete aproll. This will make the foundation easier to settle. Simply put, if there is no aproll, the walls of the house will be more prone to cracks in the future.

Usually there is a cement floor half a meter away from the root of the wall. Around the house or any building, see if it is a cement floor about one meter away from the wall.
