A 100%-solids, fl uid-applied, single-component, moisturereacted, elastomeric, coal-tar and solvent-free, modifi ed polymer that cures to form a fl exible, monolithic, waterproof membrane on vertical and horizontal surfaces. 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.
