HOW TO MOLD A SOLID CONCRETE SLAB FOR A DIRT FLOOR

The concrete slabs on the ground floor are laid on natural soil levels. These are normally cast after the completion of the foundation work. There is a difference between them and the basement 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 top topsoil is dug up and removed.

The ground floor concrete levelling are solid and not suspended like floors above this level. Preparation begins after the foundation and walls are finished. The sides of the walls have the back filled internally and externally. After this, the ground is leveled and compacted to receive the hard base. This hardcore has an average depth of three hundred millimeters. Adequate compaction and consolidation is carried out. This is the basis for the concrete that is formed.

After compacting and leveling the slab of the ground floor slab, the blanking is placed. Blinding can be quarry dust, loose chips, sand, or murram. These surfaces are then sprayed with an anti-termite treatment. The formwork for the concrete is fixed 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 milliners. The height from the bare level is three hundred millimeters.

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