Filter Units form ultimate protection against scour damage.

Filter Units being deployed for river scour protection

Ridgeway’s Filter Unit is a bespoke product specifically designed for construction in the
marine environment. It is a 100% environmentally friendly solution; the nets are made from
99% recycled polyester creating an entirely flexible structure with a stone fill inside, making
them very adaptable.

Filter Units have a one point lifting ring allowing fast and accurate installation with a reduced work force.

They are designed to protect and stabilise riverbanks, bridge foundations and offshore
foundations from scour damage, while encouraging growth of the local marine environment
as a natural habitat for aquatic life and plants.
