How Temperature Impacts Geomembranes
Geomembranes are known to be ideal for protecting the environment based upon their durability, flexibility, and resistance to chemical and temperature changes. Geomembranes are designed to be thermally stable and resistant.
Temperature can have various impacts on the properties and performance of geomembrane liners. It is important to consider the various impacts when deciding the type of liner right for your project site and environment, along with the manufacturing of the liner.
Here are 5 impacts temperature can have on geomembranes:
- Mechanical Performance: Temperature variations can influence the mechanical properties and performance of geomembranes. High temperatures can cause geomembranes to soften, which can result in reduced tensile strength and tear resistance. This can result in punctures, tears, and even damage to the liner. Low temperatures can also affect geomembrane performance. Low temperatures can cause geomembranes to become brittle and stiff, causing liners to crack or tear.
- Geomembrane Shape: Geomembranes can expand or contract with temperature variations. High temperatures will cause the liner to expand, while low temperatures may cause the liner to contract. This movement may affect the overall dimensions and shape of the geomembrane liner.
- Seam Integrity: Geomembranes are often installed by heat welding or fusion techniques. Temperature variations can affect seam integrity. High temperatures may soften the seams, making them susceptible to deformations or failures. Low temperatures can make the seams rigid, increasing the risk of cracking or separating.
- Chemical Resistance: Temperature variations can influence the chemical resistance of geomembranes. Chemicals and solvents may have different properties at different temperatures and some liners may experience changes in their resistance to specific chemicals and solvents at different temperature ranges.
- Long-Term Durability: Temperature fluctuations over time can impact the long-term durability on geomembranes. Repeated exposure to temperature extremes may accelerate the degradation of geomembrane liners.
Although temperature variations may affect your geomembrane liner durability and performance, the experts at EPI can mitigate these effects.
The designers and manufacturers we use at EPI use materials specifically formulated to withstand extreme temperature conditions. Liners can not only be designed to withstand various weather conditions, but also to withstand high heat applications like power plants.
