In the combination of GTM composite geomembrane,Geomembrane impermeable plastic film work as a waterproof membrane.Non woven geotextile work as a protect layer.Its waterproof performance depends on the impermeable geomembrane.

composite geomembranes

Impermeable geomembrane are mainly polyvinyl chloride (PVC), polyethylene (PE), ethylene / vinyl acetate copolymer (EVA), which are flexible polymer chemistry material,they all have strong ability to adapt to high deformation, corrosion resistance, low temperature resistance, good frost resistance.

Lifespan of compound geomembrane:
Composite geomembrane’s lifespan mainly depanded by impermeable plastic film.

We have a test and shows that: the o.2mm PE geomembrane in sewage will last 30 to 40 years and in clean water will last 40-50 years.Therefore, the lifespan of geomembrane is sufficient to meet the requirements of dam seepage .

What are specifications of compound geomembrane:
one geotextile and one membrane, two geotextile and one membrane, two geotextile and two membrane.

Models from 200g/m2 to 1000g/m2, could also be requested by the user according to their actual situation, as required by the individual manufacturers.

What are composite geomembrane features:
1, set the action in one of seepage and drainage, along with features such as isolation and reinforced.
2, high composite strength, peel strength, high resistance to puncture strength.
3, drainage capacity, friction coefficient, low coefficient of linear expansion.
4, anti-aging performance, adapt to a wide range of ambient temperatures, stable quality.

Engineering applications:
Composite geomembrane has excellent performance of impermeability, durability, protection. Composite geomembrane can be widely used in railway, highway, sports hall, dams, hydraulic construction, tunnel, coastal beach, land reclamation, environmental protection and other projects.
