Crystalline admixture for watertight concrete
Gives concrete "self-healing" abilities and grows together up to 0.4mm shrinkage cracks.
Waterproofing roll materials
For underground in-situ concrete structures - cold self adhesive and fresh concrete bonding roll membrane materials.
Construction joint waterstops
Waterstops and shrinkage cracks controlling profiles. Watertight up to 2.4 bar.
TPO Roofing Materials
Very long-lasting waterproofing roll material without volatile components - TPO material. It is a thermoplastic polyolefin with a 25-year warranty.
Roll Waterproofing Membranes
Roll waterproofing membranes and membranes, in general, have been the classic waterproofing material for below-grade concrete structures for a long time. Waterproofing membranes are also called classical waterproofing and "black tank" because, figuratively, the roll waterproofing membrane creates a black bowl around the outer surface of the concrete (due to bitumen-based materials), which protects the concrete structure from water and moisture.
Today, there is a lot of pressure to produce environmentally friendly materials, which is why manufacturers have started to produce more green waterproofing materials. For that, our product range includes Köster KSK SY 15, a self-adhesive cold adhesive membrane made of rubber and bitumen, which contains several times less bitumen and requires only one 1.5mm layer to achieve water, radon gas, and water vapor tightness. Secondly, we use the pre-installed roll waterproofing membrane WFP Pre-Tec 2, which we use for the casting of structures with one-sided formwork and for floor slab waterproofing. The membrane adheres to the fresh concrete, making the structure completely waterproof.
