Check Dams

Check Dams

A check dam is an erosion control 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 in a swale, ditch or waterway the velocity of sediment laden runoff is slowed thus preventing erosion.

Diamond Sock

Diamond Sock is a compost filter sock filled with aged and shredded hardwood. When installed in waterways and swales, the check dam traps sediment laden water and prevents erosion from traveling further. Stack or stake Diamond Sock for extra strength in high risk areas. Other applications include inlet protection and perimeter control.

Diamond Sock is available on continuous pallets or pre-cut wattles. Use continuous pallets for long runs or when you need to make custom cut sizes.

Available sizes:
  • 8″ x 190′
  • 8″ x 10′ (18 pieces per pallet)
  • 12″ x 110′
  • 12″ x 10′ (10 pieces per pallet)
  • 18″ x 55′
  • 18″ x 10′ (5 pieces per pallet)
  • 24″ x 35′


Excelsior Logs

The excelsior log is a great environmentally friendly and lightweight erosion control device. This check dam has a natural aspen fiber structure that dissipates energy in mild to moderate flow areas. The excelsior log can be stacked and staked with wood stakes for higher flow applications.

Triangular Silt Dike

A Triangular Silt Dike is a reusable urethane foam check dam that is wrapped in geotextile fabric in the shape of a triangle. This erosion control device has an apron of geotextile fabric that can be trenched or stapled in order to hold it in place. The Triangular Silt Dike solves multiple erosion control problems including:

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