High Density Polyethylene Impermeable Geomembrane

HDPE geomembranes are the most commonly specified liners in the construction industry. Tried and tested the HDPE membranes are resistant to most chemicals, are extremely robust and have a high stress fracture resistance. HDPE liners are available in 1mm, 1.5mm, 2mm, 2.5mm and 3mm sheet thickness.

Suitable for anaerobic digestion applications, barriers against hydrocarbons and protecting against the ingress of harmful soil based gases such as methane, carbon dioxide and radon.

HDPE geomembrane

Our technical team can advise on product selection appropriate to the application and full installation method statements.

We can supply the suitable tapes for lapped and taped jointed situations or we can offer a full design, supply and installation option providing the client with the comfort that the selected system will be installed correctly ensuring long term performance of the installed Geomembrane.

Applications for HDPE

  • Ponds
  • Lagoons
  • Anaerobic digestion ponds
  • Gas barriers
  • Hydrocarbon barriers
  • Swales
  • Attenuation tanks

Functions

Protection

Stress reduction layer to prevent or reduce damage

Reinforcement

Resists stresses or reduces deformations

Drainage

Collects and transports fluids within its thickness

Ornamental Pond at Fallow Park

Fallow Park is an exclusive housing development on the outskirts of Cannock. The rural setting of the development and close proximity to Hawks Green Nature Reserve influenced the design and installation of shared recreation areas on the site.

 

A 1400m2 ornamental pond with green space was designed to enhance the development and provide a habitat for a variety of wildlife.The ground conditions and nature of the finished pond meant that an impermeable membrane would be required to line the pond.
