A lightweight concrete layer is often placed before PIR installation to maintain the roof slope.
Hot-air welded PVC roofing — no adhesives, fire safe and flexible for life.
Waterproofing & Lining
KRCC installs PVC roofing membranes, which are easy to apply using hot-air welding. Joints are homogeneously welded (PVC to PVC), so no sealants, chemicals, adhesives or primers are needed.
PVC is self-extinguishing (safe in case of fire), resistant to high temperatures and stays flexible throughout its life span — so it can easily be joined to new material later for extensions or repairs.
