Polyguard Products, Inc. Underslab Waterproofing Membrane UNDERSEAL®

Installed prior to slab pour, UNDERSEAL® Underslab Waterproofing Membrane contains 3 layers of protection.

1. The bottom layer is a 20 mil geomembrane, highly puncture resistant and stretchable.
2. The middle layer is a 65 mil polymerized asphalt sealant, which acts as a seal and an elastomeric stress absorbing formulation. This is the primary material which guarantees a permanent seal when the concrete cracks or the joint moves above the membrane.
3. The top layer is a high strength geotextile which forms a physical bond to the concrete slab poured on top of it.

UNDERSEAL® Blindside Waterproofing Membrane is a three layer system, usually installed against vertical drainage boards which are fastened to lagging. Flow 15P & Low Flow drainage boards.

1. A very high strength and puncture resistant, but conformable, polyethylene film layer is installed against the drainage board.
2. A thick layer of elastomeric, stress absorbing polymerized sealant is adhered to the high strength polyethylene.
3. A high strength geotextile is the last layer. This geotextile forms a physical bond to the concrete foundation wall poured against it.
