Product Overview

Root resistant waterproof membrane is a special SBS modified bitumen waterproof roll with anti-root formula. It can effectively resist the piercing damage caused by plant roots, maintain the integrity of waterproof layer long-term. Adopt torch-on hot melt construction, excellent water impermeability, ageing resistance and puncture resistance, the preferred waterproof material for green planting roof projects.

1. Lay rolls from low position to high position, align and straighten each roll, then roll back.
2. Heat evenly while rolling forward, then paste and seal the edge tightly.
3. Finish full roll paving first, then carry out edge sealing; apply adhesive or polyurethane coating on seams if necessary.
4. Paving sequence: For connected roofs with different elevations, construct high span first then low span. For the same roof, lay reinforcement at drains, internal corners and special shaped areas first, then large-area waterproof membrane.

• Never point torch or flame towards people during hot melt operation.
• Do not carry out torch-on construction on windy days.
• Control flame distance and heating duration to avoid overheating and damaging membrane. The liquefied gas tank must stay at least 20m away from ignition point with dedicated staff on duty.
• Avoid fuel overflow when refilling the torch burner.
• Prevent direct skin contact when using adhesive.
• Smoking and open flame are strictly prohibited at material stacking area on construction site.
