Application Method

1. Ensure the roof deck is smooth, clean, and dry (Moisture < 9%), then apply bitumen paint homogeneously.

2. Heating and Melting Method: Heat the membrane and roof surface until nearly melted, then install with 5-10cm overlaps.

3. Cold Adhesive Method: Pour cold adhesive homogeneously then roll the membrane to stick it fully.

4. Inspection: Post-application inspection is required to ensure no air bubbles or folds.

Frequently Asked Questions

What is the difference between SBS and APP modified bitumen?

SBS (Styrene-Butadiene-Styrene) modifier increases the cold resistance, making it ideal for colder climates. APP (Atactic Polypropylene) modifier increases hot resistance, suitable for regions with higher temperatures.

Which reinforcement material should I choose?

If your local temperature changes significantly throughout the year, Polyester is recommended due to its superior elongation properties. Fiberglass is best for projects requiring high tension without the need for elongation.

What surface materials are available for the membrane?

We offer a variety of finishes including Polyethylene film, Aluminum film or foil, Sand, and Granulars in different colors to suit various aesthetic and functional needs.

What are the primary application methods?

The membrane can be installed using either the "Torch-on" (heating and melting) method for a fully bonded seal or the "Cold Adhesive" method depending on project requirements and safety constraints.

Can this membrane be used for underground waterproofing?

Yes, it is highly suitable for unexposed places such as basements, toilets, underground structures, and foundation walls.

What is the standard thickness and size of a roll?

The standard thickness ranges from 1.5mm to 5mm. A typical roll is 1 meter wide and 10 meters long, though lengths can be customized.
