Sinking concrete is usually shown in the form of uneven, cracked or sunken concrete slabs. It is a serious problem always worth fixing and is often caused by the following:
- Too much weight: The weight of the slab is pushing down on the soil, causing the slab to sink.
- Soil erosion: Too much water washes away the soil beneath a slab causing a hole.
Most contractors will recommend repairing a sinking slab by demolishing the damaged area and pouring new concrete. This strategy is an extremely expensive and a time-consuming way to fix a sinking concrete slab. The other option frequently presented is mudjacking which is cumbersome and costly. Foamjection should be your first choice.
