Overview
SBS membranes stay flexible at low temperatures; APP membranes resist heat and UV better. Polyester or glass-fibre reinforcement gives tensile strength and dimensional stability.
Performance depends on the primer, minimum laps, fully sealed edges and detailing at corners and penetrations. Exposed membranes need a mineral-surfaced cap sheet or protection layer.
Uses
- 01Concrete flat roofs and terraces
- 02Basement walls and slabs (external tanking)
- 03Water tanks and underground tanks
- 04Concrete roofs of factories
Selection and acceptance checks
- Check thickness, polymer type and reinforcement
- Check laps, torched edges and pipe details
- Flood test before laying the protection layer
Reference standards
- ASTM D6164
- ASTM D6222
- EN 13707
- EN 13969
For reference only. The standards for each project follow its design documents, current Vietnamese codes and the investor’s requirements.
