SilTrap Check Dams and SilTrap BioBags are short-term BMPs that can be deployed quickly for an effective solution to prevent further erosion before more permanent BMPs can be established. They slow the stormwater down enough to trap sand, silt, and clay in and upstream of the bag. They fit the contours of the land, hold together, and can be removed easily when saturated and used as intended. Check Dams and Biobags have the least retention and shortest lifespan of any erosion control BMPs. They are not designed for areas with high water velocities and can become buoyant and easily displaced if not staked down properly.

Installation: Position the SilTrap Check dam or BioBag so that no gaps can allow runoff to reach the unfiltered storm drains. Stake bio bags to keep them in place in concentrated flow areas. If bio bags are used in high-traffic areas, use additional measures to help prevent them from being run over (for example, flagging several feet high).
