What We Do
wht we do


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

Geomembranes, Geotextiles, GCLs, Geocomposites, Geogrids, Shear Strength, Geosynthetic Cementitious Composite MatsDurability, Plastics/Rubber, AdhesionTextilesWaterproofing Sheets, PipesAccelerated Weathering, Bitumen & Geonet.


The tests marked (U) are UKAS Accredited and those marked (F) are accredited under our flexible scope.  Click here for our current Schedule of Accreditation.  Tests which are technically equivalent tests to those which are accredited can 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.
