Silt booms are available in a variety of sizes and materials and are made to order. Silt booms have a foam buoyancy chamber supporting a deep skirt. The skirt can vary from a few metres deep to as many as seven metres deep. Skirt material is woven polyethylene, but can also be a non-porous fabric. Particles as small as 50 microns can be trapped with fine goetextile material. Most silt booms are used in waters with low or no current. Booms in strong currents require additional longitudinal strength to cater for the extremely large force exerted on the skirt of the boom.
Application: Ideal boom for use when dredging, excavating and piling or where machinery operates in and around water. Silt Booms trap and contain sediment and silt, preventing it from contaminating other parts of the waterway.
Silt Boom is designed to control the settling of silt suspended in water by providing a controlled area of containment.
The boom allows water to flow freely, while acting as a barrier against sediments and other materials.
Silt boom is manufactured to suit each customers specific requirements. Booms can be made in lengths up to 30 metres and skirt heights of 1m to 6.5m. Skirt can be sectionalised to suit changing water depths.
- All fabric joins are stitched with strong webbing to join geotextile fabric.
- Sections can be joined together to form a continuous barrier with lace-up eyelets (budget range) or zip joins and strengthening clips (premium range).
- Float size varies depending on the depth of skirt.
- The wovewn geotextile fabric has a 200 micron pore size, effectively trapping particles greater than 50 micron.
- Regular maintenance checks should look for growth build up and silt blinding the boom.
- Clean and store the reusable silt boom for the next project.
