TPO Membrane for tunnels- substitute of EVA
•TPO waterproof roll material is polypropylene filament non-woven fabric
•Intermediate reinforcing layer and thermoplastic polyolefin copolymer composite coil
•Material TPO, calendering composite
•TPO waterproof coil products
•
•Membrane thermoplastic polyolefin TPO is made of vinyl and propylene flexible material with advanced polymerization technology and special formula
•
•Waterproof material; High tear strength, breaking strength and resistance
•
•Puncture strength.
•High strength structure. The unique composite structure of two membranes and one cloth makes the product extremely resistant to puncture and damage to the plant root system.
It has high tensile strength, tear resistance and puncture resistance, and has a solid structure, which is an important indicator to ensure the waterproof quality of engineering projects.Lightweight and easy to install.
Compared with similar products, TPO waterproofing membrane has excellent performance in various performances, and its weight is lighter. It is easy to install using hot-melt welding and auxiliary materials, which greatly saves manpower and man-hours.Safe and non-toxic.
The TPO waterproofing membrane has passed the authoritative testing of the National Chemical Building Materials Testing Center and the National Polymer Materials and Products Quality Supervision and Inspection Center: the safety evaluation standards for drinking water transmission and distribution equipment and protective materials are up to standard.Stable in nature.
TPO waterproofing membrane is chemically stable, will not biodegrade, will not be corroded in the environment of aquatic plants, and is also extremely resistant to acidic and alkaline solutions. TPO has good flexibility and excellent performance at ambient temperature -45°C to 90°C.Durable and environmentally friendly.
TPO waterproof liners have a lifespan of up to 50 years and are recyclable and recyclable.

Construction technology of TPO waterproofing membrane
General requirements for construction conditions of TPO waterproofing membrane
•Soft base (usually soil)The compaction degree of the plain soil base should be more than 90%, and the surface of the base should be solid, flat and clean. There are no protrusions, branches, gravel, metal wires and other debris on the surface of the base layer.Set a non-woven protective layer of not less than 200g/ on the base layer;The surface of the base layer is required to be dry and free of water;If the plain soil base needs to be equipped with a drainage and exhaust device, it shall be designed by relevant professionals;When designing the top of the TPO film with stone or other materials, it is necessary to lay non-woven fabrics or set up a concrete cushion;When the groundwater level is higher than the TPO membrane pavement layer, construction precipitation is required, and a specially designed precipitation scheme is required.
Rigid base (generally concrete/stone/brick base)Rigid bases are easily damaged by factors such as frost heave and settlement. Therefore, concrete construction should be constructed in strict accordance with specifications to ensure the stability of bases, and expansion joints or other measures should be set up if necessary;The surface of the base layer is thoroughly cleaned, without honeycomb hemp surface, sharp protrusions and steel bars, etc., to ensure that the base layer is flat, clean, and free of visible water;On the base layer similar to concrete, in addition to the construction with full adhesion, a non-woven fabric of not less than 200g/ should be laid between the coil and the base layer as a protective layer;
