NWG224 TPO (Thermoplastic Polyolefin) Waterproofing Membrane

This product is a sheet-form polymeric waterproofing material made from thermoplastic polyolefin (TPO) resin as the base material and manufactured using advanced processing techniques.

Product Structure

Product Categories

Based on their composition, the products are classified as homogeneous rolls (code H), rolls with fiber backing (code L), and rolls reinforced with fabric (code P).

Specifications and Dimensions

Length: 15 m, 20 m, 25 m;  Width: 1.0 m, 2.0 m; Thickness: 1.2 mm, 1.5 mm, 1.8 mm, 2.0 mm. (Other specifications may be agreed upon by the supplier and the buyer)

Code Marker

Mark in the following order: product name (code TP0 sheet material), type, thickness, length, width, and this standard number.

Example: A Class P thermoplastic polyolefin waterproofing membrane with a length of 20 m, a width of 2.00 mm, and a thickness of 1.50 mm is marked as follows:

TP0 Sheet Material P 1.50 mm/20 m × 2.00 mm GB 27789-2011

Product Features

• Contains no plasticizers, so it does not age due to plasticizer migration and can maintain its waterproofing properties over the long term;
• Fabric-reinforced TPO waterproofing membranes offer high tensile strength, high mechanical strength, fatigue resistance, and puncture resistance; fiber-backed TPO waterproofing membranes adhere more easily to the substrate, while homogeneous TPO waterproofing membranes have good ductility and can be formed into various shapes, making them suitable for handling complex details;
• Excellent resistance to high and low temperatures; the rubber retains its flexibility even at temperatures below -50°C and maintains a certain level of mechanical strength at higher temperatures, making it suitable for use in a variety of environments;
• Good chemical resistance; resistant to corrosion by acids, alkalis, salts, and oils;
• Resistant to heat aging; good dimensional stability.

Construction Methods

Construction is typically carried out using adhesive bonding, mechanical fastening, or the pre-laid reverse-adhesive method. Specialized prefabricated components are used to address detailed joints and complex areas.

Applications

It is primarily used for waterproofing, moisture-proofing, and seepage-proofing projects in building basement slabs, side walls, urban subways, tunnels, and utility tunnels.

Packaging, Storage, and Transportation

• Packaging: Rolled material should be wound around a rigid core and packaged in plastic bags or woven bags.
• Storage: Rolls should be stored in a well-ventilated area protected from direct sunlight and rain. The storage temperature should not exceed 45°C. Rolls of different types and specifications should be stacked separately. When stacked flat, the stack height should not exceed 5 layers; when stacked vertically, they should be stacked in a single layer. Contact with acids, alkalis, oils, and organic solvents is prohibited. Under normal storage conditions, the shelf life is one year.
• Transportation: Prevent tilting and lateral pressure during transportation; cover with a tarpaulin if necessary.
