Carbofol® geomembranes are manufactured using high density polyethylene (HDPE). Carbofol® is produced in various thicknesses and with either smooth or structured surfaces.

Carbofol® geomembranes provide a complete seal against even the most toxic substances. Routinely installed as a component of landfill base seals as well as caps, Carbofol® protects groundwater from contamination. Even the strictest regulations and controls for the storage, filling, handling, manufacturing, treatment and use of contaminated liquids, such as Germany’s Water Conservation Act (WHG) and Britain’s Environmental Protection Act (EPA), are easily satisfied with Carbofol®. The product is also suitable for potable water and non-toxic containment applications such as water conveyance structures, canals or ponds. Individual solutions can also be developed for steeper slopes utilising our structured-surface material with higher friction coefficients for greater safety.

In 1989 Carbofol® became the first geomembrane certified by the Federal Institute for Material Testing and Research (BAM). Currently, Carbofol® HDPE (smooth and structured) 2.5 and 3.0 mm thick are BAM certified for use in landfill engineering. For groundwater protection applications, Carbofol® geomembranes (1.5 mm and thicker) are certified by the German Institute for Construction Technology (DIBt). Further international certifications for Carbofol® have been issued in, amongst others, most European countries. Extensive manufacturing and third-party quality control allow complete documentation of production from the raw material to the finished product. Carbofol® is extremely durable, and is both chemically and UV resistant. Carbofol®’s glazed surface immediately reveals any accidental damage so repairs may be quickly undertaken. Welding of seams and repairs is done by state-of-the-art welding equipment which records all pertinent data as welding is performed. Air pressure tests or vacuum tests verify the integrity of the seams so you can be confident in the finished job
