PVC Geomembrane sheet

 

PVC geomembrane sheets are polymer sheets that belong to the geosynthetic class consist of flexible plastic sheets with high tensile strength.

Material: PVC

Specifications:

-Width: more than 1.6 m

-Length: 15 m

-Thickness of 1-4 mm (provide permanent sealing if properly installed).

Applications: Fully waterproof, sealing various surfaces.High flexibility (over 250% elongation). They are also known as geomembrane pool liners and the use of these sheets in the dam, tunnel, and swimming pool construction. 

Features: Fast and easy installation

Instruction of use: Rolls of these sheets are spread at the project site; then, their edges are fused via thermal welding, creating a uniform appearance.

توضیحات

PVC geomembrane sheets are a geosynthetic product and consist of flexible plastic sheets with high tensile strength.

They are available in rolls 1.6 m wide and 15 m long with thicknesses of 1-4 mm.

These sheets are fully waterproof.

High flexibility (over 250% elongation), long life (50 years), incredible tensile strength (over 15 MPa), and attachment only using heat guns and without adhesives or additives have made this product an excellent choice for most tunnel and dam construction projects in Iran.

The unique properties of this product, including economy and ease of use, have led to its increased use in various industrial applications, with prospects for use instead of traditional damp sealing in pilot plant and domestic applications.

PVC Geomembrane Sheet: How to use and install

The PVC geomembrane rolls are opened into a sheet, which is then spread over the desired surface.

The edges of the sheet are fused together using a heat gun, creating a uniform and impermeable surface.

If the membrane is expected to be in contact with soil, a geotextile or felt layer is spread under it as drainage and protection for the membrane.

Advantages of PVC geomembrane sheets over-sprayed seals and adhesives

  • Using PVC geomembranes is considerably more economical.
  • PVC sheets retain the seal during cracks and dynamic loading of structures, while adhesives, additives, and sprayed seals crack along with the concrete, destroying the sealing in the process.
  • Moreover, repairing PVC sheets is simple while sprayed seals require material remake and handling by a specialist in repairs.
  • PVC membranes have a very high physical strength and stand axial and lateral forces of up to 13 MPa, while adhesive and concrete layers lack significant physical strength and are used only based on the assumed strength of concrete.

Benefits of PVC geomembrane sheets

  • Very high reliability in preventing the passage of water and damp
  • 50-year lifetime during which the flexibility of the sheet is maintained
  • High flexibility, lack of need for foundation, and capability of sealing surfaces of different geometries
  • Simple and fast installation using heat guns and without adhesives
  • Easy maintenance by fusing sheet segments onto the punctured or torn area
  • Economical competitiveness

Polyethylene geomembrane sheets are recommended in damp sealing applications in which the membrane is exposed to sunlight.

Polyethylene geomembrane sheets are recommended in damp sealing applications where the membrane comes into direct contact with drinking or irrigation water.
