Product Details
SBS Modified Bitumen Waterproof Membrane is a strong, resilient, non-woven polyester mat that is coated with flexible, polymer-modified asphalt and is smooth.
Weidun Waterproof has a full line of SBS Modified Bitumen Waterproof Membrane.
Due to its elongation characteristics, a resilient polyester mat core allows it to resist splits and tears.
Specially formulated modified asphalt gives a lasting performance.
Easy to apply by torching.
Available guarantee of up to 20 years.
Application
Substrate Preparation:
All substrates must be sound, dry, free from grease, dirt, or other contaminants, and must be reasonably smooth.
Priming:
A layer of primer should be applied to the prepared surface. The primer helps to improve the adhesion between the membrane and the substrate.
Torching Equipment:
Fire safety is the most fundamental while applying bitumen membranes. The torch equipment must be in good working
condition and properly connected. Make sure there are no gas leakage and a sudden gush of fire.
Installation:
The bituminous waterproofing membranes are unfolded on the site and laid firmly on the surface slowly while torching its underlayer (torch layer).
Bonding:
The seams and edges of the membrane are sealed using the torch equipment or propane torch to melt the SBS-modified bitumen on the edges of the membrane.
This helps to create a continuous and waterproof surface.
Storage:
Membranes delivered to the site are to be stored in a covered area or be covered with a protective sheet until
required for installation. Rolls are to be stored vertically to prevent damage to the ends.
