Do you need stone under a concrete slab?

Asked By: Alex B Date created: Jun 10, 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.

What is normal concrete cracking?

Asked By: Farhad Farahi Date created: Jun 23, 2022
