SBS Waterproofing Membrane

SBS modified asphalt waterproofing membrane is a waterproofing membrane made of polyester felt as the base, styrene-butadiene-styrene (SBS) thermoplastic elastomer modified asphalt as the impregnation and coating material, and covered with isolation materials on both sides.

Product Features

-Excellent high and low temperature resistance, suitable for both hot and cold regions.

-Chemical corrosion resistance, mold resistance, and good weather resistance.

-High tensile strength, water pressure resistance, high elongation, good puncture resistance, fatigue resistance, good dimensional stability, super strong aging resistance, and strong adaptability to base shrinkage deformation and cracking.

-Polyester tire base fabric, as a reinforcement layer, is resistant to puncture, abrasion, and tear, improving material strength and effectively resisting damage and destruction from the upper and lower surfaces.

-Good construction performance, hot melt bonding, and reliable and durable joints.

Scope of application

Waterproofing and anti-seepage of various industrial and civil building roofs, underground engineering, as well as waterproofing of structures such as swimming pools and fire water pools. Waterproofing for municipal engineering projects such as subways, tunnels, concrete paved bridge decks, sewage treatment plants, and landfill sites. Waterproof of water conservancy facilities such as canals and pools.

Construction technology and methods

1. Construction Method:

The hot melt method is used, using a flame to melt the hot melt adhesive on the bottom layer of the hot melt waterproofing membrane. The membrane thickness must be greater than 3mm.

2. Construction Process:

Base cleaning - Applying base treatment agent - Sealing joints - Laying additional layers - Positioning and trial laying - Laying membrane - Rolling, degassing, and compacting - End fixing and sealing - Cleaning, inspection, and repairs - Inspection, acceptance, and finished product protection

3. Notes:

3.1. The waterproofing base must be strong, dense, free of peeling or sand, flat, and solid. The waterproofing base must be dry, with a moisture content no greater than 9%. The base treatment agent must be evenly applied (full-bond method).

3.2. Position the membrane, lay the membrane, and heat the membrane's bottom layer with a flame heater. Once the membrane's surface is melted, roll it out immediately. During rolling, remove any air from underneath the membrane to ensure it lies flat and firmly bonds to the base.

3.3. Perform additional treatment on detailed joints, seal overlaps, and end caps. After qualified acceptance, apply a protective layer to the polyethylene film-covered membrane.
