SKU: SEDIMAT
Sedimats are used in waterways during in-stream construction activities (such as pipe laying or dredging) to trap disturbed sediment that may pollute aquatic habitats downstream. They are a simple, yet effective, biodegradable matting, which are fixed to the stream bed, and do not impede water flow.

Description
Sedimat is an effective tool for the protection of streams from sedimentation damage during in stream construction activities such as utility installation, culvert replacements, ditch maintenance, and bridge work.
It is a flat 1.20 x 3.00m pad which is laid singly or in multiples on the streambed immediately downstream of the worksite. Sediment disturbed by construction is carried along the streambed by the current until it encounters Sedimat. The sediment then settles through the upper layer of jute mesh and into a layer of wood wool. A lower layer of hessian prevents the sediment from escaping.
After construction is complete, the mats are removed and can be staked to the stream bank and seeded to provide immediate stream bank stabilisation. Because the mats are entirely biodegradablethere is no need for disposal. The sediment mixed with the rotting wood wool provides a seedbed for germination and growth of the seed mix.
Sedimat is packaged individually and is easy to store, handle and transport. It can be installed on a streambed using either stones or stakes and can be placed in any configuration or number to provide desired coverage. It may be used alone or in conjunction with other methods of stream protection such as coffer dams, culverts or silt screen.
