TUFF-N-DRI® H8 membrane elongates to span concrete shrinkage cracks. As concrete settles, cracks naturally form in the foundation wall. TUFF-N-DRI is specially formulated to span these cracks, sealing against water leaks and keeping water out of basements.
Water pressure can build up on the outside of basement walls during a rain storm. TUFF-N-DRI H8 withstands 8 ft. of water pressure (hydrostatic head pressure while competitive product usually provides around 1 ft. of resistance. This means that even over cracks TUFF-N-DRI is protecting basement walls and keeping water out while competitive membrane fails at as little as 12 in. of water pressure.
