Foundation Conditions in Oklahoma City
Oklahoma City sits on highly expansive red Permian clay. This clay can change volume by more than 15% between wet and dry states - one of the most extreme shrink-swell values of any soil type in the US.
Oklahoma City endures severe climate extremes: summer droughts that crack the soil and shrink foundations, followed by intense spring storms that saturate the clay and cause heaving. This cycle repeats annually and is the primary driver of the region's very high foundation repair rates.
Common Foundation Types in Oklahoma City
Oklahoma City homes primarily use post-tension or conventionally reinforced concrete slabs. Many homes also have pier-and-beam sections under older additions. Foundation repair is essentially a standard maintenance item for Oklahoma homeowners.
Most Common Foundation Problems in Oklahoma City
