Trusted Concrete Raising Contractor Serving Lesterville, South Dakota
Throughout the years, as rain and melting snow enter into the earth below your concrete it will grow and shrink. As this soil shifts and moves around, voids can be created. The slab can settle into these voids and eventually form cracks in slabs or gaps between slabs.
Why Does Concrete Settle?
There are a number of factors and conditions that can contribute to settling concrete slabs. Some reasons could be major changes in the moisture content of the soil from wet weather or a longer period of dry weather that could cause the soil to become depleted of water and contract.
The moisture content in the soil will change over time, it will cause the concrete on the soil to become uneven. If the soil becomes saturated with water due to improper drainage, this water will cause the soil to become weak and no longer be able to support the concrete.
If the weather is hot and no rain falls for extended periods of time, it will cause soil to shrink. As the soil dries out, it will make cavities form under the concrete slabs. As time progresses, these holes cause pressure and put unnecessary stress on the concrete slab and will ultimately cause it to crack.
During construction, soil is removed and replaced. After this is completed it is critical that it is compacted to the original density as when it was removed. If the soil is not correctly compacted, it can rapidly speed up the forming of spaces under the slab poured above. These voids will put undue stress on the slab and can cause settling over time.
Where We Can Level Concrete
Any place there is soil below your concrete, there could be the danger of needing concrete leveling. These are some of the main locations that we've seen both business and residential property owners needing our services:
The Solution: Polyjacking
The trusted alternative to tearing out and re-pouring your cracked or sinking concrete is polyjacking.
A relatively new advancement that makes use of expanding polyurethane foam to raise and repair these sloping slabs back to their intended position. Historically a method called mudjacking has been used to perform a similar procedure. The advantage that polyjacking has over mudjacking is the polyurethane foam will expand to fill the cavity and harden to permanently restore the concrete in position.
