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 in a swale, ditch or waterway the velocity of sediment laden runoff is slowed thus preventing erosion.
Diamond Sock is a compost filter sock filled with aged and shredded hardwood that traps sediment laden water and prevents erosion from traveling further. Diamond Sock is commonly used in waterways and swales. 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.
- 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′
The excelsior log is a great environmentally friendly and lightweight option for check dams. Excelsior logs have 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 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 reusable option for:
- Ditch check dams
- Diversion dikes
- Drop inlet protection
- Temporary ditch liner
- Stream & pond protection
All of these check dams are VDOT Approved Materials for EC-4 , Type 2 Rock Check Dams
