Cartonal N1100 is best suited for applications where the backfill
material is fine sand and in replacement of 3mm thick bituminous protection boards .  Cartonal is needed in this instance to reduce friction on the membrane, and stop the chemical, and root attack on the membrane.Cartonal N1300 is better suited for situations where the backfill
material is a mixture of sand and small rocks, and in replacement of 4mm thick bituminous protection boards .  Apart from the elimination of friction, this higher resistance board is needed to take the abuse of the backfill or the friction of the concrete, pumped to that depth. The impact of these two materials increases as the depth increases.Cartonal N1500 is best suited for projects with high protection
requirements such as airports, hospitals, hotels, and high cost structures. Cartonal N1500 is a rugged board that withstands a lot of abuse. It can take up to 1500 newton of puncture resistance, and has 2.15 kg / cm² in compressive strength. The board can used in replacement of 6mm thick bituminous protection boards .  And has all the advantages of the other Cartonal Boards.Cartonal Cartoscreed is the best protection board for sensitive job
sites where the protection requirement is ultra high. Cartoscreed has been specifically designed to replace Screed of up to 10 cm thick with significant improvements. Screed cracks under load, creating sharp edged pieces which can tear the membrane that it is supposed to be protecting; whereas Cartoscreed spreads the load across its whole surface and does not break or crack. Cartoscreed has a compressive strength of 5.5 kg/cm², and therefore can carry the entire weight of the structure easily before it compresses. Not forgetting Cartoscreed’s superior puncture resistance of 2000 newton, which is the highest attainable in price and weight comparison.Pro-Drain is a combination between a drainage board, and a
protection board. As a protection board it has the superior puncture resistance of the Cartoscreed sheet, and as a drainage has perforations on one side to allow water and other liquids to pass through the sheet and down to the drainage system. This alleviates any hydrostatic pressure on the structure’s retaining walls. Pro-drain is best suited for areas where there is a high water table, or a transient water table that releases large quantities of water on a seasonal or occasional basis. The best way to describe this system is to think of it as a 16mm² drain pipe distributed side by side along the length of the structure .
