How to Prepare the Ground Before Pouring Concrete Slab

Step 1 Dig the ground down to the proper depth Determine the proper depth by establishing the height of the concrete slab Add 2 inches to the depth for gravel if the soil is normally moist or has a high concentration of clay Most concrete slabs will sit 1 to 2 inches higher than the dirt and 2 to 3 inches below the surface of the dirt

3 Reasons Why It s Important To Use Crushed Stone Under Concrete Slabs

A Level Surface Adding crushed stone under your concrete slab will provide a level surface for your foundation Simply pouring concrete onto the ground will expose it to elemental erosion that will cause cracking and sinking Similarly if there are roots or plants under your slab they may rot and cause unevenness

The Difference Between Plain Concrete & Reinforced Concrete Al Manaratain
