How long will concrete leveling or raising last?
Although every situation is unique, concrete usually sinks because of water erosion, compaction of soil underneath the slab, or movement on an incline. A-1’s process of filling with an extremely dense material dramatically improves the compaction of the underlying soil, however, some soils i.e. peat contain high levels of organic material and may be difficult to stabilize for long periods of time. Water erosion is probably the most critical issue. Improper drainage, broken or misaligned pipes or utilities, or surface cracks may allow water to “undermine” the soil under the slab. With proper drainage and sealing of cracks and missing expansion joints*, leveling can last indefinitely.
