In HouseGuard’s Wall Ninja system, TruDry waterproofing and Dow foam board work with the maker’s Ninja channel to manage moisture and energy loss. With a concrete floor poured on top of the Ninja channel and against the foam board, moisture migrating through the wall is directed behind the board, under the channel, and under the floor to the sump pit. The system achieves R-5 to R-15 insulation values. houseguard.com
