Why Does Concrete Sink?
Everybody has seen old concrete that is uneven and tilted. The concrete was poured evenly, but it became crooked over time. There are a few reasons that your concrete walkway or foundation is sinking. Concrete sinking is commonly caused by excessive moisture and soil type, and our concrete services in Columbia can resolve these issues.
Moisture and Soil
Weak soil shifts after some time. Depending on where you live, the dirt will become weak, sink, and erode. Concrete needs to be supported by the dirt underneath the slab; the concrete slab can become damaged if it experiences too much moisture. Insufficient support can cause concrete slabs to sink.
Moisture damage is one of the main causes behind many foundation issues. Underground moisture dissolves the dirt underneath the structure. If caught early, moisture barriers or a drainage system can be set up to repair the damage suffered by the structure.
Our Concrete Solutions
CNT Foundations can repair your problems with:
- Polylift - Polyurethane foam is lightweight and waterproof, with a quick curing time that enables the concrete slab to be walked on just minutes after the concrete slab is level.
- Mudjacking - Slurry is injected beneath your concrete slab, filling the void caused by soil erosion.
- Concrete removal and replacement - Sometimes concrete is damaged and needs to be replaced or removed. CNT Foundations can get rid of your old cement and pour another, improved concrete slab.
