These are SBS-modified elastomeric bitumen-based waterproofing membranes developed for cold climate conditions. The elastomeric structure, which maintains its flexibility down to −20°C, prevents micro-cracks from reflecting onto the waterproofing layer in applications where structural movement and thermal stress are high. Polyester felt carrier standard and thick models (P-320, P-420) are used for foundations, shear walls, and double-layer top membranes; while the mineral-coated topcoat model (M-320) is used on cold-climate roofs.
FIELDS OF APPLICATION • Building foundations in cold climate zones, • Shear and retaining walls, • Lightweight metal and precast roofs, • Sloped and flat concrete roofs (M-320 — mineral-coated topcoat), • Pressurized groundwater waterproofing, • Top layer in double-layer waterproofing systems.
