The materials used in our projects are constantly developed, improved and tested to provide the best performance in the most demanding service conditions. We collaborate with experts in geosynthetics and with the most renowned producers of geosynthetics. A long-life geomembrane exposed to high UV radiation and extreme temperatures is standard practice for us. Durability of SIBELON^® geomembranes is continuously verified in the field and in external independent laboratories. We feel comfortable saying that our exposed geomembranes have a service life that easily can exceed 50 years and reach 100 years or more.
