Voids are created under the concrete slab by the shifting of the soil or by a reduction of soil volume. In most cases, concrete settlement can be traced to the dehydration and shrinking of the soil under the concrete, water erosion, poorly compacted subgrade and the washout of soil. The concrete may not be sufficiently strong enough to hold the load, causing the stressed concrete slab to crack, break, and eventually settle to fill the void. When concrete settles, it can cause serious damage to the structures they support. Regardless of the cause polyrathane lifting/leveling is a quick and effective solution, it is a fraction of the cost to tearing out and replacing, with minimal impact to your landscaping.
