Why does concrete sink?
Concrete sinks as the soil underneath a slab either compacts (the water in the ground has evaporated to the point that it has shrunken) or a void or pocket has been created due to erosion from running water (from a downspout or a natural sloping of the ground toward your cement) or rainwater, causing a concrete slab to sink, settle or become uneven.
The weather in our Kansas City region is usually fairly dry. When a region experiences less rain or moisture, the water in the soil evaporates, and dries the soil, causing the cement slabs to sink into the ground unevenly. Winter snow and ice or improper draining onto your driveway can be especially problematic for concrete. Make sure when the ground thaws each spring, you check your driveway and sidewalks for gaps between the concrete slabs. If you think you may have an issue with sinking concrete, call us.

What is Mudjacking?
Traditional mud jacking also referred to as ‘slab jacking.’ is a process of raising a section of concrete by drilling many holes approximately 2” wide (and up to 4” wide in some cases) in the concrete and pumping a mixture of clean fill dirt, water and cement through the holes effectively pushing the concrete up from below. Traditional mud jacking materials can weigh 100-120 lbs. per cubic foot. Once the cement is lifted, the holes are patched.
