NORDCEM is a special inorganic osmotic-type cement.
NORDCEM penetrates in solution into the support’s capillary pores, reacts chemically by fixing the calcium hydrate and precipitates irreversibly in insoluble micro-crystals that plug the internal pores (chemical waterproofing).
Meanwhile, on the surface of the treated support, NORDCEM leaves an impermeable cementitious layer without pores, capable of withstanding water counterthrust.
The chemical nature of NORDCEM was specially formulated to allow for:
• The breathability of the support.
• The retention of the waterproofing effect for a long time.
When used in combination with NORDCEM PRIMER applied the day before, NORDCEM develops a deep (up to 1.5 cm beneath the surface) waterproofing effect also in low-porosity structures, such as concrete.
This system is ideal for guaranteeing counterthrust impermeability in the presence of high negative-thrust water pressure, which typically occurs with:
• Floor slabs.
• Foundation slabs.
• Earth-retaining walls.
• Swimming pools.
• Tanks for containing waste and drinkable water.
NORDCEM is used for:
• Waterproofing of structures subjected to continuous water pressure (positive and negative), such as basements, foundation slabs, earth-retaining walls, lift cavities, goods hoists, swimming pools, tanks, channels, tunnels.
• Waterproofing of tanks used to contain drinking water.
