Wattles (sometimes called logs) are berm-shaped filtration products that act as sediment barriers that slow water and sediment flow. They are also used as barriers to stop sediment and debris from entering storm drains. Wattles are made from either natural materials (straw, aspen or coir fibers) or recycled rubber. Logs that are made from natural material can be left on-site after the project is completed. Straw wattles are most commonly used to stop soil flow on hillsides. Guaranteed weed free, one of the greatest attributes of straw wattles is that they can be bio-degradable, which saves time and money.
Logs made with coir fibers can be pre-vegetated to assist in getting a good stand of vegetation on slopes. This is especially beneficial in pond and stream conditions where water elevation tends to fluctuate, creating a tough environment for establishing vegetation.
