EXPERT LINING INSTALLATIONS
JCW Gas Membranes provides the supply and installation of high-performance lining systems for ponds, attenuation basins, lagoons, reservoirs, swales, balancing ponds and containment structures throughout the UK.
Our experienced installation teams work with a wide range of geosynthetic materials to provide durable, long-term containment solutions for water management, environmental protection and infrastructure projects.
Whether your project requires stormwater attenuation, SuDS compliance, leachate containment or environmental protection, we can deliver a complete lining package tailored to your site’s requirements.
Our lining solutions
We install a comprehensive range of containment systems, including:
HDPE Geomembranes
LLDPE Geomembranes
Geosynthetic Clay Liners (GCLs)
Geotextile Protection Layers
All materials are selected based on project-specific requirements, including chemical resistance, puncture protection, ground conditions, design life and environmental performance.
Geosynthetic Clay Liners (GCLs)
GCLs provide a highly effective hydraulic barrier consisting of a layer of sodium
bentonite encapsulated between geotextiles or bonded to a geomembrane. They offer an environmentally robust solution for attenuation basins, ponds, landfill applications, lagoons and containment structures.
Our installation teams are experienced in the deployment of GCL systems, ensuring correct overlap detailing, protection measures and integration with geomembrane components to achieve optimum performance.
Attenuation Basins & Sustainable Drainage Systems (SuDS)
Modern attenuation basins form a critical part of Sustainable Drainage Systems,
helping to control surface water runoff and reduce flood risk.
JCW installs lining systems designed to:
- Retain water within attenuation structures
- Prevent infiltration into surrounding ground
- Protect groundwater resources
- Improve hydraulic performance
- Meet project-specific environmental requirements
Our team can assist with detailing around headwalls, pipe penetrations, outfalls,
manholes and anchor trenches to ensure a fully integrated solution.
Quality Installation
All installations are undertaken by trained operatives using industry-recognised techniques and quality control procedures. We work closely with contractors,
consultants and developers to deliver compliant, durable and cost-effective containment systems.
From small attenuation ponds to large-scale infrastructure basins, JCW Gas Membranes offers a complete service from material supply through to installation and project completion.
