Mudjacking vs. PolyLevel Foam Jacking: What's More

Actually, before we talk about concrete leveling and lifting, let's take a few moments to understand why concrete slabs sink in the first place. Concrete is strong, durable stuff, but it's only as stable as the soil that lies underneath it. Over time, that soil can compact or even wash away due to several factors, including rain, drought, or simply the fact that the fill soil deposited there
