Where is waterproofing necessary?
Although the joints between the NUDURA form units are tight, below grade a waterproofing is still necessary. NUDURA sells a peel and stick waterproofing, that is easy to apply and carries a warranty of two years. This membrane must cover the foundation walls. In situations where you have an attached garage, the below grade wall shared with the basement must be covered, and a 4’ (1200mm) overlap to the adjacent walls.
