Geomembranes

Keyline Geotechnics provide and install a wide range of polyethylene/polypropylene lining membranes – geomembranes. Geomembranes are now widely used for the containment of liquids, solids and gases in a variety of construction applications. Keyline Geotechnics has substantial experience and knowledge in ‘Geomembrane Engineering’ and this section covers a range of examples of past projects where the Company’s products and specialist services have been utilised. Keyline Geotechnics welcome enquiries from all those parties involved in the design and construction of lined facilities.

Japanese Knotweed Control

Japanese Knotweed is recognised by the Environment Agency as the UK’s most invasive species. Knotweed can grow up to 10cm a day. It is a statutory offence to cause or allow Japanese knotweed plants to grow in the wild, whilst great care must be taken over disposal, as waste regulations categorise all of the plants and contaminated soil as controlled waste. Adjoining owners may take civil action seeking damages due to the spread of Japanese knotweed onto their property. Keyline has a range of tried and trusted costeffectiveenvironmentally aware japanese knotweed solutions, to fit clients’ timescales, budgets, and site specific requirements, as well as meeting all regulations. Solutions can also be applied to Himalayan Balsam, Giant Hogweed, and most other imported invasive plants. 

Geosynthetic Clay Liner

Geosynthetic Clay Liners (GCL) are high performance environmental liners comprised of a layer of low-permeability sodium bentonite encapsulated between geosynthetic carrier layers. They provide hydraulic performance equivalent to one metre of compacted clay, with a total GCL thickness of less than 10mm. GCLs are self-sealing if punctured, and are manufactured in large rolls that require just a simple overlapped seam. Fast and easy to install, as well as being highly cost effective, GCLs provide a superior choice for both designers and contractors. 

Bentomat SS100®
Bentomat SS100® is a reinforced needle-punched Geosynthetic Clay Liner (GCL) specifically designed for landfill, surface water impoundments and secondary containment.

Bentomat CL®
Bentomat CL® is designed for better performance under more variable conditions, by providing permeabilities ranging from 10 to 1000 times lower than standard GCLs. Ideal for applications where additional hydraulic performance is required, the CL range incorporates a flexible plastic membrane liner that adds an extra layer of protection to the GCL.
