Poly Board is a semi-flexible polypropylene based board for waterproofing membrane protection.
PolyBoard is extremely strong in puncture and injury resistance. It is engineered to resist puncture at over 1100, 1300, 1500, 2000, 24000 and 2600 Newton as per ASTM E-154.
PolyBoard differs from any other materials used to protect the waterproofing membrane as it enjoys flexibility which enables its use for tacking corners, protrusions, rounded surfaces and also uneven surfaces.
PolyBoard is not affected by mineral oils, solvents, acids, based, and salts. These elements are usually found in contaminated water tables and soil compositions. This product does not absorb water, which adds to the impermeability of the waterproofing membrane.
Poly Board is applied on hot asphalt liquid membranes, torched applied asphalt membranes and on rubber based waterproofing membranes.
