Advanced geosynthetic clay liners for durable lining projects
Hydroclay GCL's (Geosynthetic Clay Liners) are widely used in the construction of decorative lakes, garden ponds, wetlands, newt ponds, reed beds, lagoons, swimming ponds, school ponds, golf clubs, Aquaponics & fisheries, as well as more industrial applications such as in SUDS, attenuation pond lining projects, anaerobic digestion basins, canal lining and river & stream diversions.
Because Hydroclay does not require specialised welding equipment or labour, Hydroclay GCL's can be installed with minimal instruction or supervision and at a cost, despite its many benefits, that is often less than regular liners.
Versatile clay lining solutions for every sector
Our geosynthetic clay liners offer a cost-effective, durable alternative to conventional synthetic membranes without requiring specialist welding equipment.
Garden ponds and decorative lakes
Create beautiful water features, natural swimming ponds, and school habitats with a flexible, natural clay barrier designed for long-term water retention.
SuDS ponds and attenuation basins
Reliable containment for sustainable drainage systems, anaerobic digestion basins, and industrial lagoons engineered for demanding site conditions.
Wetlands, reed beds, and habitats
Eco-friendly sealing solutions ideal for newt ponds, wildlife wetlands, aquaponics, and commercial fisheries that require chemical-free containment.
Canals, rivers, and stream diversions
Robust hydraulic engineering liners designed for canal restoration, watercourse diversions, and large-scale civil infrastructure projects.

Why choose Hydroclay geosynthetic clay liners?
Hydroclay GCLs combine natural sodium bentonite clay with durable geotextiles to form a permanent hydraulic barrier. Unlike traditional flexible membranes, our liners are self-sealing if punctured and can be installed swiftly with basic site equipment and minimal supervision, significantly reducing overall project costs.
Straightforward installation with low project overheads
Eliminate the expense of heavy welding apparatus and specialized installation crews. Hydroclay liners unroll easily on prepared subgrades, allowing rapid placement in all weather conditions for faster project completion.
