Geomembrane Lifespan: How Long Does It Last?
How long does geomembrane last? Here is a short explanation of geomembrane lifespan, one of the questions geomembrane users ask most often.
How long a geomembrane lasts depends on whether it is exposed or not. The plasticizer, filler, carbon black and additive content is assumed to meet the GRI GM-13 standard with the following composition.
Service life: unexposed conditions
Conditions with no sun exposure are found in applications such as:
- Landfills
- Coal Ash Yards
- Road embankments
- Drainage
The geomembrane service life study for unexposed conditions was carried out in 2002 and consists of 3 stages (Stage A, Stage B, Stage C)
A : Antioxidant Depletion Time
B : Induction Time to the Onset of Degradation
C : Time to Reach 50% Degradation
The total predicted service life of a geomembrane depends on site temperature. Below is the average service life of geomembrane in unexposed conditions.

The table above shows that at a normal temperature of 30 degrees Celsius, the service life of a geomembrane can reach 166 years
Service life: exposed conditions
UV-exposed conditions are found in applications such as:
- Aquaculture ponds
- Embung (small retention reservoirs)
- Artificial ponds
- Water storage ponds
Field results from Europe gave the following findings
The table above shows that in exposed conditions, the service life of HDPE geomembrane can exceed 36 years.
As part of our commitment to geomembrane quality, we provide a 5-year UV warranty on SOLMAX and VIROMAX geomembranes.

Geosynthetics for Cover Soil on Slopes
Slopes are a common feature of construction projects. Slope areas need special attention because they are a critical part of a project design and are usually found in structures such as embung (small retention reservoirs), landfills and the like. These slope areas may fail for several reasons, such as a lack of reinforcement, saturated soil […]
Building a Geomembrane Biofloc Pond with HDPE
Biofloc is a farming technique for catfish, fish, shrimp and other farmers that uses probiotic bacteria to process the organic waste produced from digestion and leftover feed. A geomembrane biofloc pond helps make this technique very effective at increasing productivity and maintaining water conditions. Biofloc ponds usually use a circular steel frame lined with tarpaulin.
