Many factors are involved in settling concrete:


  • Poor Soil Conditions. Clay-rich soils are elastic.  They expand and contract with moisture content.  As soils become saturated with water, clay expands and loses its strength.  This condition allows slabs to sink.  Often heavy rains, melting snow, and plumbing leaks can result in a sunken slab.


  • Compaction. Many homes are built on backfilled soils.  If  soil is not compacted correctly, backfill will slowly and unevenly compact, allowing slabs to settle.


  • Tree Roots. Trees and large shrubs can consume tens of gallons of water a day.  Loss of water in soils located near concrete results in settling of slabs.


  • Erosion.  Improper drainage, including misplaced downspouts, can cause soil instability by creating areas of saturated soils, allowing slabs to settle.

There are two methods to raise and support sunken or unstable concrete slabs: polyurethane foam concrete raising and mudjacking.


Polyurethane concrete raising and repair uses a foam material that is injected under the slab.  When the components of polyurethane are mixed, a reaction causes the material to expand. 


By drilling small holes and pumping material under the concrete slab, expanded foam fills any voids beneath the slab and raises concrete.


Chesapeake Concrete Raising, LLC uses the polyurethane concrete raising method because the holes are smaller than the mudjacking method and the concrete repair is less noticeable when completed.  Driveways, sidewalks, patios, steps, and stoops are all made safer and more stable with minimal cost and maximum benefit.
