One reason it is used as a backfill or sub-grade material. As with all material, it has to be placed correctly and compacted properly. Sand needs to remain damp as well as other material before placement of the concrete. If you want to build a road, use gravel, but this does not mean you will not have issues.

Do you need stone under a concrete slab?

Asked By: SiegeX Date created: Jun 23, 2022

Because concrete is a very porous material, it will absorb any moisture that it contacts. This can cause pooling. Without crushed stone, pooling water will settle under it and erode your slab. Adding a layer of crushed stone will add proper drainage, as well as create a barrier between your slab and the ground.

Asked By: Stanley Mohlala Date created: Jun 08, 2022

The number of coats that you will need to apply depends on how deep the hole is. Any hole under half an inch should only require one coat. Deeper holes will need two coats. Just like when you're plastering an entire wall, make sure you scratch the first layer of plaster before you apply another coat on top.

Can you pour concrete on clay?

Asked By: Daniel Fortunov Date created: Jun 14, 2022

Unfortunately, if you have clay-heavy soil, then you may run into difficulty when pouring a slab. The clay can compress under the weight of the concrete, causing the slab to shift or sink over time. With proper preparation, however, it's possible to pour a slab on clay soil without encountering these problems.
