Technical overview

## Water ingress at roofs, flashings, and prepared building substrates

Josoor supplies two distinct waterproofing membrane groups: liquid-applied membranes and sheet membranes supplied in rolls. Choose Liquid Waterproofing Membranes or Roll Waterproofing Membranes below to explore the relevant product families, technical characteristics and applications.

### Where this applies:

Roofs, terraces, roof details, protected under-tile areas and below-ground structures, plus engineered lining and containment with the appropriate sheet-membrane grade.

Tell us where water is entering, the substrate condition, and whether a complete system is required — we’ll help identify the relevant membrane family.
