What We Do

Tests we regularly provide are listed below, and are grouped into the following categories:

Geomembranes, Geotextiles, GCLs, Geocomposites, Geogrids, Interface Shear Strength, Durability, Plastics/Rubber, Textiles, Waterproofing Sheets, Pipes & Accelerated Weathering.

 

The tests marked (U) are UKAS Accredited.  Click here for our current Schedule of Accreditation.  Other technically equivalent tests to those accredited can also be provided as accredited under our flexible scope.  Please contact us for more information.

 

If there is a test you require that does not appear on this list please do not hesitate to contact us, we have a wide range of test equipment and expertise available.
