Carbofol® is a chemical resistant geomembrane with smooth of structure-embossed surface for sealing applications.

Carbofol® is multifunctional

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-toxiccontainment 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.

Advantages of Carbofol®

  • high interface friction angles with embossed structured surface
  • complete quality control from the resin to the final product
  • installation advantages with up to 9.40 m wide liner
  • high Melt Flow Index allows an excellent
  • welding performance smooth edges with removable
  • plastic tape for clean welding surface and overlap lines
  • durable product with more than 40 years of project experience
  • also available according to GM-13 and with BAM and DIBt approval
  • ISO 9001 certified
  • CE marked

Carbofol® is safe

In 1989 Carbofol® became the first
geomembrane certified by the Federal Institute for Material Testing and
Research (BAM). Currently, Carbofol® HDPE 507 (smooth and structured)
2.5 mm thick are BAM certified for use in landfill engineering. For
ground water pro tection applications, Carbofol® geomembranes (2.0 mm)
are certified by the German Institute for Con struc tion Technology
(DIBt) and are of course also available according to GM 13 requirements.
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 extremly chemically and UV resistant. Welding of
seams and repairs is done by state-of-the-art welding equipment which
records all per tinent data as welding is per formed. Air pressure tests
or vacuum tests verify the integrity of the seams so you can be
confident in the finished job.

Carbofol® is economical

Utilising the most advanced welding
technology and with authorised installation experts, quick and efficient
installation programmes are possible. The superior weldability of
Carbofol® means quicker installation facilitating a speedier approval of
your projects.

Carbofol® is simple

Side markings on the rolls indicate
proper overlap distances for the welding crews and protective
edge-strips main tain a clean surface prior to welding. Structural
details such as attachments and penetrations are easily carried out
directly on site. The entire process is effortless for the installer.


Decades of successful applications are
proof of the high quality of Carbofol® and our commitment to excellence.
Industry knows Carbofol® for its problem-free manufacturing and
installation even when meeting the strictest permitting requirements.
This translates into the safest and highest quality available for your
