Rasco 1K PMBC low shrinkage S

Single component, polymer-modified bitumen thick coating (PMBC) with polystyrene, for waterproofing of structures below ground in accordance with EN 15814 and DIN 18533 - also against water under pressure

Protects underground structures according to DIN 18533 part 3 permanently against W1-E (ground damp and pressure-free water), W2.1-E (moderate action of pressing water = 3 m immersion depth), W3-E (pressure-free water on earth-covered ceilings) and W4-E (splash water and ground damp at wall base).

It can be applied to vertical and horizontal surfaces, foundation slabs, foundations and cellar walls. Can be used on all known and suitable mineral substrates.

The consumption rates shown are minimum values. A separate professional levelling of the substrate, for example by a scratch coating is expected. According to DIN 18533 part 3, a layer thickness addition of at least 25% of the minimum dry layer thickness is to be added. MDLT = Minimum dry layer thickness, WLT = Wet layer thickness
