The foundation of this 1970's home was installed without a proper footing. Gradually sinking over the years, causing windows and doors to stick along the way, eventually settled 7 inches. With the potential to continue sinking, the homeowner needed to address the issue.
Push piers were used to lift and stabilize the structure. The piers were successfully able to lift the home 3 inches (anymore would have affected plumbing or caused severe cracking). With the push piers being so deep into the earth, it is unlikely the home will ever settle again.
Additionally, spray foam, similar to our PolyLevel product, was applied to the foundation wall and soils surrounding it, it order to provide some frost protection. Frost causes heaving and other harmful effects to the foundation, so this was also a crucial step to address.
