Filter Bags

Even the best quality silt fencing erected properly will not contain all the sediment within a construction site for two reasons:

  1. disturbed earth may exist beyond the site perimeter; and
  2. Silt can accumulate from access areas where vehicles are entering and leaving the site.
  • Filter Bags capture silt that leaves the site, for the above reasons
  • Filter bags are placed at the entrance to inlet drains.

The Sediment Control Centre provides ready made filter bags in sizes 0.8m (SC21), 2m (SC23) and 3m(SC29) and continuous lengths. Where OH&S issues are a concern, rubber filled bags are a lightweight, reusable alternative.
