Rock bags – Ridgeway Marine and Filter Units

The filter unit has a simple design. Constructed of recycled synthetic material and filled with stones it protects marine structures from scouring processes while harnessing and maintaining the marine environment. Boasting a one-point lifting ring it provides a more cost effective method in comparison to traditional solutions. Its natural flexibility makes it very adaptable to the undulating topography of river and sea beds making it a key product for offshore and marine civil engineering works.

Environmently-Friendly

The filter unit net is made from 61% recycled plastic bottles and are 100% environmentally friendly.

Flexible

Stone fill inside the mesh net bag makes the entire structure flexible and adaptable.

Rapid Construction

Creation and installation of Filter Units is so simple, it can be implemented with a minimal workforce.

Cost

The cost per unit and installation savings combined with the reduced lifetime O&M leads to a significant cost reduction.

What is a Filter Unit?

As Filter Unit is made of synthetic fiber, it is strong against corrosion that it has a long durability. At the same time, it has durability against ultraviolet rays equivalent to 30 years exposure under the sun.
