Leaking Crack Repair by Twin State Basements in Vermont & Western New Hampshire

• FlexiShield – Crack repair system designed to flex with the foundation and channel water from a leaking wall crack below the slab. It consists of a strip of the FlexShield drainage matting and textured urethane sealant and flexes with the foundation as it shifts during seasonal changes. Comes with a 5-year warranty and it can be painted.

Additional Options for Wall Cracks

• HD FinishShield – A 16mil, Class A (Fire Rated) wall vapor barrier recommended as a durable wall covering. It’s perfect for basement walls where a customer may not finish right away but would like the protection against moisture, mold, mildew, humidity, and potential wall leaks. The measured average permeance of FinishShield is 0.015 perm.

• ThermalShield – A 90mil, Class A (Fire Rated) foil faced and true white poly wall vapor barrier. It’s the wall vapor barrier of choice for adding additional installation reflecting indoor heat back into the basement space. Save energy and protect against moisture, mold, mildew, humidity, and potential wall leaks. The measured average permeance of ThermalShield is 0.014 perm.

Both systems work in conjunction with the GrateDrain™ System, shielding the living space from water vapor transmission and channeling wall leaks down to the GrateDrain™ system, to be pumped out with any groundwater seepage.
