Why Concrete Driveways Sink

Why Concrete Driveways Sink

Concrete driveways have a horrible tendency in the Houston and the surrounding areas of sinking. Most all driveways are poured in sections divided by an expansion joint. These expansion joints are usually treated lumber, redwood, or in some cased they are made from a synthetic fiber board. These expansion joints are needed and are designed for the soil conditions that are in Houston and the surrounding areas, by allowing the panels to move independently of one another if there is expansion or shrinkage of the soil. Engineers understand that the potential vertical rise (PVR) on soil that is predominantly clay can be 2-3 inches in some case.

There are a few things that a homeowner can do to help prevent some of the underlying issues:

  • Extend gutters away from the concrete
  • Back fill any ruts or voids next to the edges
  • Prevent water from entering in the expansion joints (Joint Sealant)
  • Pay attention for shifting and trip hazards
  • Look for cracking, or cracks worsening

Over time if water can penetrate under the driveway panels voids could be created. Voids are empty air pockets under the concrete that provides no support for the structure. Concrete driveways are designed to support the weight of vehicles by its chemical make up and steel reinforcement. This design considers that there will be a solid compacted and well-maintained subgrade. If the subgrade is substandard to design, then the concrete may crack or sink.
