Geomembrane
EPDM geomembrane

It can be used for waterproofing of building roofs, providing a reliable waterproof barrier to prevent rainwater from penetrating into the interior of the building and protecting the building's structure and internal facilities from water damage.


Features

1. Special modified molecular structure, can be hot air welding directly , lap solid and reliable, no environmental pollution,solve the current domestic and foreign EPDM adhesive lap existing problems effectively ;

2. Long life, anti-aging, used for more than 20 years for roofing material, the underground &the building;

3. High elongation, tensile strength&heat treatment size change is small;

4. Resistant to plant roots, anti-puncture, do planting roof waterproof layer;

5. Low temperature and excellent flexibility, -45 ℃ without cracking, adapt to temperature changes.

FREQUENTLY ASKED QUESTIONS

What is the thickness of HDPE geomembrane?

Usually 0.3-3mm, customization is acceptable.

Can the geomembrane be covered with soil?

The geotextile usually needs to be backfilled with a soil layer for protection, such as lotus ponds and fish ponds, which require backfilling with a 20 cm soil layer.

What are the application areas of HDPE geomembrane?

HDPE geomembrane can fully meet the application requirements of industries such as sanitation, water conservancy, construction, municipal engineering, gardening, petrochemicals, mining, salt industry, agriculture, and aquaculture.

What is the general service life of geomembranes?material is PVC drainage pipe made of?

The service life of geomembranes is a range, and the specific years depend on many factors. The service life when exposed to the outside can reach more than 5 years; when used underground, it can reach more than 50 years.

What are the types of geomembranes?

There are many types of geomembranes, mainly including HDPE, LDPE, PVC, composite geomembranes, etc. Dingrun specializes in the production of geomembranes, welcome to consult.
