Our anti-pollution filter dams are intended to retain and filter waste during maritime or river works (gravel, dust, cement, suspended silt, oils, plastic bags, etc.).
The suspended solids dam can also be an effective flexible barrier to limit the invasion of swimming areas by various macro-waste (floating debris, plastic bottles and bags, branches) or duckweed.
The BTM dam (dam for maritime works) consists of standard sections of 25 meters in length (possibility of different lengths on request).
Each section of the dam consists of a float 250 or 300 mm in diameter and a standard submerged geotextile skirt (draft) 2.50 or 5 meters high (possibility of different float diameters and skirt lengths on demand).
- Float composed of a succession of cylinders of flexible closed cell foam giving the boom perfect buoyancy in the event of accidental tearing and great flexibility allowing it to perfectly match the movements on the surface of the water.
- The connections between the sections are quick and easy to implement and do not require any tools (bolted PA plate for the float part and by lacing for the submerged curtain).
- The filtration skirt of each filter dam is easily replaced (halyard attachment system).
- The filtration curtain is lightly weighted in order to match the shapes of the seabed while preserving flora and fauna.
