Henry MiraSEAL is a fast curing, one component elastomeric, solvent free, moisture cure waterproofing membrane designed to provide a cold technology alternative to hot applied rubberized membrane systems or replace conventional hot mop felt ply and/or pre-formed sheeting systems. It is applied in a high build two ply system or single ply application which cures through reaction with atmospheric moisture to provide a heavy-duty “seamless” rubber-like, impervious membrane. Due to the moisture-reactive and non-gassing properties of the membrane, it provides tenacious adhesion to concrete substrates above- and below-grade, preventing lateral water migration, even with moisture present in the concrete. The inherent toughness and resilience of MiraSEAL enables it to bridge structural or shrinkage cracks that may develop in the substrate. MiraSEAL can be applied wet on wet in a horizontal application resulting in reduced installation time.
