Check Dams

A check dam is a device that prevents erosion by slowing the velocity of water.  Check dams are one of the most commonly used products that exist in erosion control. By placing the check dam structure in a swale, ditch or waterway, the velocity of sediment laden runoff is slowed thus preventing erosion.

Triangular Silt Dike

A triangular silt dike is a urethane foam structure that is wrapped in geotextile fabric in the shape of a triangle. This silt dike has an apron of geotextile fabric that can be trenched or stapled in order to hold it in place. The silt dike is a cost effective and lightweight option for:

  • Ditch check dams
  • Diversion dikes
  • Drop inlet protection
  • Temporary ditch liner
  • Stream & pond protection

Excelsior Logs

The excelsior log is a great environmentally friendly and lightweight option for check dams. Excelsior logs have an interlocking natural aspen fiber structure. The excelsior log is used for energy dissipation in mild to moderate flow areas. The excelsior log can be stacked and staked with wood stakes for higher flow applications.

Compost Filter Sock

Another check dam option is compost filter sock. Diamond Sock is one compost filter sock option available at Colonial. Diamond Sock is commonly used in waterways and swales that are attempting to support vegetative establishment. This compost filter sock traps sediment laden water in its unique media matrix and prevents erosion from traveling further. Diamond Sock is available in a number of different diameters. Diamond Sock is sold on a continuous pallet in the sizes 8″ x 190′ and 12″ x 110′. It is also available in 10′ pre-cut sections for smaller applications. This material can be staked in and stacked for extra strength.
