The concrete slabs of the ground floor are placed on the natural levels of the terrain. These are normally cast after the completion of the foundation works. There is a difference between them and the base floors. Basements are made below ground level and formed above. They can be used in houses, garden sheds and outdoor houses. When throwing them, the level should be lowered by about two hundred millimeters. This ensures that the topsoil is excavated and removed.

The concrete slabs on the ground floor are solid and not suspended like the floors above this level. Preparation begins after the foundation and walls are finished. The sides of the walls are internally and externally padded back. After this, the soil is leveled and compacted to receive the hard base. This hardcore averages three hundred millimeters deep. Adequate compaction and consolidation is carried out. This is the base for the concrete that is formed.

After compacting and leveling the core of the ground floor slab, the blinding is placed. The blinding can be made of quarry dust, gravel, sand or murram. An anti-termite treatment is then sprayed on these surfaces. The formwork for the concrete is then attached to the edges of the foundation wall. This is the thickness of the concrete. The thickness of the concrete is from one to one hundred and fifty pinwheels. The height from the stripped level is three hundred millimeters.

On the concrete of the ground floor, waterproof membranes are placed after blinding. A thousand gauge diotene sheet is used for this. The next mesh reinforcement is placed on the sheet. After this concrete is mixed and poured on top. Leveling is done with the working height of the formwork. Concrete mixes are one part cement, two parts sand, and four parts ballast. After pouring, the concrete is watered for at least seven days to cure. Then you can proceed with the placement of walls.
