PVC Geomembrane for Reservoir Project

 

 PVC sheet is a high polymer waterproof material, which is processed by using the Polyvinyl Chloride (PVC) as the base material, mixing with plasticizers, age resistor, UV absorbers and other additives.

Features:
1.High Tensile strength, excellent resistance to tear and puncture.
2.Strong adhesion with the concrete, effectively prevent the phenomenon of water channeling .
3.Lap with pre- self-adhesive side lap to ensure the seamless of waterproof system.
4.Perfect resistance to acid&alkali,weather and aging.
5.Simple operation, high work efficiency, low cost.
6.Non toxic, tasteless and be environment friendly.

Scope of Application:
1. The waterproofing of the Industrial or civil construction's roof, including the planting roof, flat roof, sloping roof.
2. Waterproofing of the underground building: Including reservoirs, dams, canals, and all parts of the basement water seepage.
3. Tunnel, granary, civil air defense projects, garbage landfills, and other man-made lake.

 

Operation points:
Generally, heat the jointing with the hot air or electric heating with hot air or welding by electricity.
Waterproof construction of complex parts can be used matching PVC special accessories.
Technical Capacity Index (Ref to Chinese Standard GB12952-91) .

 

Cautions:
1. Do not put the membrane on a polluted, water and ice ground.
2. Construction of waterproof layer operations can't be crossed, device shall be installed on the waterproof layer, parts should be done to strengthen the basis of device and to take protective measures.
3. Do not touch the waterproof layer with thorn sharp objects after it's has been completed, don't put sundries or any additional buildings above the waterproof layer to avoid damaging it.

 

Storage and Transportation:
Be under the dry and well-ventilated condition; avoid sunlight and raining. Stand straightly; lay flat and be packed in the same direction without no more than 5 layers.
Shelf life: One year.
