Ridgeway have the capabilities to provide filled units (all sizes) anywhere in the UK and Ireland.

Testing completed on the product during the developing stage (back in 1986) confirmed the net has a life time of 30 years against UV.

During testing at the developing stages, it was also confirmed that the filter unit net will last 50 years in saline water.

Filter units can be filled with 50-200mm stone but it must have a specific gravity of 2.65.  Quarried stone can be used but for a more carbon reduction option a river cobble can also be utilised as a suitable fill.

The filter unit underwent hydraulic model testing at HR Wallingford’s facility to analyse the products stability in comparison to rip rap.   It has also been strength tested at Lloyds British and was basically pulled until destruction.

Filter units are annually LOLER tested by a certified LEEA.
