For under-slab applications, the rigid foam insulation typically should be installed over a gravel base, with a poly vapor diffusion retarder between the gravel and insulation. Additional insulation is applied along the edges of the slab, because that is a primary surface for heat loss.

Do you need stone under a concrete slab?

Asked By: dano Date created: Jun 19, 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.

Can you pour concrete on clay?

Asked By: miken32 Date created: Jun 19, 2022

With proper preparation, however, it's possible to pour a slab on clay soil without encountering these problems.
