Self-adhering Waterproofing Membrane

MFM Building Products

SubSeal is an advanced 40 or 60 mil, self-adhering waterproofing membrane that is engineered to be a multi-purpose sheet suitable for vertical or horizontal applications. These membranes are designed for extreme moisture protection and aggressively bond to poured concrete and other building materials to eliminate the movement of water under the membrane. The product is designed for use on features such as through-wall flashings, windows, sills, pot shelves, parapet walls and many other applications. The product meets ASTM D 1970 and ICC-ES ESR 2783.

Pre-applied Waterproofing System

Grace Construction Products

Preprufe Plus is an enhanced version of Preprufe that allows for faster installation and stronger adhesion at the seam. The product forms an adhesive bond to the concrete placed against it and thus does not rely on the earth outside of the building (which could erode or fall away from the building over time) to confine or hold the Preprufe membrane in place. The system has colored zip strips at the top and bottom of the seam area on the edge of the roll. Once the zip strips are removed, a magnetic adhesive to adhesive bond is achieved at the seam that is stronger than the standard product.
