When installing any pond, there are many factors that will influence your choice of liners. When choosing a liner, consideration must be given to the size, gradients, capacity, required aesthetic finish, method and time of year the installation is taking place. Geosynthetics Ltd offers a range of lining solutions which accommodate for all of the above criteria.

One example is when Geosynthetics Ltd were approached for a solution for The Faraday Project which required a wildlife pond using a geomembrane welded in situ to cast in waterbar with a minimum lifespan of 25 years. Geosynthetics proposed the Bentotex GCL as a solution that provided a self-healing waterproof membrane that required no specialist welding; being able to be installed by Pond Life themselves; the proposed solution resulted in a large saving on the project labour costs.

The solution

Bentotex® is a high specification geosynthetic clay liner, comprising of high-quality natural sodium bentonite encapsulated between two woven and non-woven needlepunched polypropylene geotextiles.  Bentotex® adopts unique self-seaming overlap technology which does not require any additional treatment of its longitudinal edges.

Bentotex® Geosynthetic Clay Liner

The Bentonite clay gives the Bentotex® Geosynthetic Clay Liner its unique ‘self-healing’ properties. Once the product is hydrated and confined under the required minimum of 300mm cover material; if the product is punctured by an object, Bentotex® seals around it, healing itself. This is one of the main reasons it is specified for a large proportion of public works contracts and landfill applications. Bentotex® is not compromised by root penetration and is ideal for reed beds and wet systems.

Applications:

• Water reservoirs, dams and river embankments
• Liquid waste disposals sites, transfer stations, secondary containment
• Transport infrastructure
• Canals
• Solid waste storage and disposal sites

Advantages:

• Easy to install
• Self-healing
• Excellent slope stability
