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 0.75mm, 1mm, 1.5mm, 2mm, 2.5mm and 3mm sheet thickness.

HDPE liners are suitable for Anearobic Digestion applications, barriers against Hydrocarbons and protecting against the ingress of harmful soil based gases such as methane, carbon dioxide and radon.

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.
