Polypropylene Protection Boards

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.

Application

Poly Board is applied on hot asphalt liquid membranes, torched applied asphalt membranes and on rubber based waterproofing membranes.

• 1. Hot applied liquid membrane: Poly Board is simply laid down on top of hot asphalt before it cools down.
• 2. Torched applied asphalt membrane: before application of Poly Board, the exposed side of the membrane shall be lightly torched in separate spots. When the top exposed layer of the membrane changes into a sticky shiny layer, Poly Board protection boards are applied with gentle pressure.
• 3. Rubber waterproofing membrane: a solvent based glue (Patex or similar) is applied as an adhering agent between the waterproofing membrane and the protection board.
• 4. Poly Board is also used as a protection boards for tiles of various finishes during construction phases.
