What causes foundation cracks?

The majority of cracks in concrete foundations are a result of shrinkage in the concrete. Shrinkage is a normal occurence and should not be a cause of great concern. Fixing cracks yourself can be done through a process called low presssure crack injection. Urethane is forced into the crack sealing the crack all the way through the wall. The process takes about one hour and a typical kit costs about $100. DIY kits can be purchased at www.thebasementoasis.com or contractor can be found through contacting www.cmemanufacturing.com.
