FAQ About SBS Waterproofing Membrane
Q: What makes SBS waterproofing membrane different from other waterproofing products?
A: SBS waterproofing membrane contains modified styrene-butadiene-styrene polymers that give it exceptional flexibility at low temperatures and excellent recovery properties. Unlike traditional bitumen membranes, SBS-modified membranes maintain their elasticity in cold climates and can bridge minor cracks in the substrate. The polymer modification also increases the membrane's resistance to mechanical damage and extends its service life.
Q: How long does SBS waterproofing membrane typically last?
A: When properly installed and maintained, our SBS waterproofing membrane has a typical service life of 20-30 years. The actual lifespan depends on factors like climate conditions, UV exposure, and substrate movement. In protected applications (such as beneath pavers or insulation), the membrane can last even longer. Our premium formulation includes UV stabilizers and high-quality SBS polymers to maximize durability in exposed conditions.
Q: Can SBS waterproofing membrane be installed in cold weather?
A: Yes, one of the key advantages of SBS waterproofing membrane is its excellent cold-weather performance. Our membrane remains flexible down to -20°C (-4°F), allowing for installation in cooler temperatures when many other waterproofing products become brittle and difficult to work with. For optimal results in cold conditions, we recommend keeping the membrane rolls in a warm storage area before installation and using torches with proper flame adjustment to ensure complete bonding.
Installation Guidelines
For best results with your SBS waterproofing membrane:
- Prepare a clean, dry, and smooth substrate free of debris
- Prime porous surfaces when required
- Allow membrane to relax at installation temperature for 24 hours
- Overlap seams by minimum 100mm (4 inches)
- Use proper heat welding techniques for torch-applied versions
- Inspect all seams and terminations carefully
