What are the chances of the basement leaking?
During construction the plywood joints are sealed full length with butyl caulking, the walls are covered with a vapor barrier prior to being back-filled, partially with P-rock to facilitate drainage and eliminate leaks do to hydraulic pressure caused by soil expansion around the basement. These measures and the in-ability of the PWF walls to crack, as is common in masonry construction, virtually eliminate the possibility of leakage.
