Biodegradable Sediment Entrapment Mat
Greenfix River Mats are suitable for use in natural and artificial channels. Each mat consists of 2 layers of burlap, with Straw & Excelsior. All four sides are closed by natural thread stitching.
How does River Mat – RM100 work?
Secured to the bed of the water course and placed downstream of the disturbed area, River Mat RM100 lies flat and traps sediment borne along the bed on the current. Being flat the River Mat RM100 does not cause disruption of the water flow or affect the current. Mats are staked or weighted in place with stones sourced from the channel.
River Mat – RM100 can help with the control of:
Downstream Sedimentation: A common problem resulting from civil engineering works for drainage, flood alleviation and other site run off or work on the watercourse. These can release quantities of sediment downstream of the works.
Environmental Impact: Disturbing sediment can have a detrimental effect on wildlife and plant habitats, smothering vegetation, insects and fish.
Waterway blocking and contamination: Disturbed Sediment can block drains, culverts and headwalls, and reduce the depth of pools. Sediment build up against structures can also be detrimental to the integrity of bridge and dock piers.
Don’t Dispose, Reuse…
Once works are complete the filled River Mats can be reused as a nutrient rich biodegradable embankment stabilisation mat. The River Mat will be saturated with silts and sediments and when lifted from the watercourse can be placed on a slope to provide the ideal base for planting.
