Check Dams

Check dams prevent erosion by decreasing the velocity of water and filtering sediment from runoff. Install these erosion control products in swales, ditches or waterways to stop water and prevent downhill erosion. If you are looking for an alternative to the rock check dam, explore our ditch check options including the Triangular Silt Dike, Silt Sock and Curlex Sediment Log.

The Curlex® Sediment Log®, also known as an Excelsior Log, is one of the industry’s most popular erosion control wattles.

This wattle check dam is filled with American Excelsior’s patented Curlex® fibers, made from renewable Great Lakes aspen wood fibers. Each Curlex® fiber is curled and barbed to create an interlocking matrix.

The excelsior fibers are wrapped in a degradable netting that has an open structure. The porous netting allows runoff to flow through the check dam while trapping sediment. The Curlex® Sediment Log filters runoff at 35 gallons per minute (ASTM D5414).

The natural aspen wood fiber filling dissipates energy in mild to moderate flow areas. For high flow applications, stack or stake the Curlex® Sediment Log® and secure it in place with Oak Stakes.

Compost Filter Silt Sock is an erosion control wattle filled with composted wood chips and wrapped in tightly woven netting with a 1/8-inch opening. Stack or stake Compost Filter Sock wattles in waterways and swales to trap sediment, filter runoff and prevent erosion.

A 10-foot wattle works for most check dam designs. If you need a longer wattle, consider a single continuous pallet and cut to the desired size. Custom cut wattles in the field by cutting the end and tying off with zip ties.

What is a Rock Check Dam?

The most traditional ditch check is the rock check dam.

A rock check dam is a barrier of rip rap stone that is dumped or stacked across a swale. As water travels through the swale, the rocks slow down the water and filter the sediment. These dams are effective but not user-friendly. Rock dams require the contractor to purchase a load of stone, transport it to the site, dump it in place and spread it purposefully across the ditch.

In lieu of traditional Rip Rap Rock Check Dams, we suggest a Triangular Silk Dike, Compost Filter Silt Sock or a Curlex Sediment Log.
