A 1m x 2m x 4mm thick, semi flexible, polypropylene based board, double layered with 5mm integrated perpendicular support spacers at 4mm intervals, to be applied as a protection to the waterproof membrane.
On Hot Applied Asphalt Liquid Membrane: CARTONAL boards are simply laid down on top of hot asphalt before it cools down On Torched Applied Asphalt Membrane: The exposed side of the membrane should be lightly torched in separate spots. When the top exposed layer of the membrane changes into a sticky shiny layer, CARTONAL N1500 protection board is applied on to it by gentle pressure. A minimum overlap of 3 to 5cm is recommended. On Rubber Based Waterproof Membrane: A solvent based glue is to be applied as an adhering agent between the waterproof membrane and the protection board.
CARTONAL boards are not affected by mineral oils, solvents, acids, bases, and salts that are usually found in contaminated water tables and in soil components. CARTONAL boards do not absorb water which add to the impermeability of the waterproof membrane. CARTONAL boards do not rust, rot corrode, or support bacterial growth.
CARTONAL differs from any other materials used in protecting the waterproof membrane. CARTONAL board enjoys flexibility that enables its use in tackling corners, profusions, rounded and uneven surfaces. CARTONAL board can be installed easily even by unskilled labor.
