Henderson Turf specializes in the practice of preventing wind and water erosion for agriculture, construction, and land developments. Effective erosion control is an essential technique in preventing water pollution and soil loss. Henderson Turf specializes in many areas of erosion and sediment control including:
Check Dam Devices
Devices installed in swales, storm flow zones of channels, and ditches that are designed to slow the velocity of concentrated flows, and filter sediment. Size of the channel, steepness of grade and volume of stormwater runoff are all factors that go into choosing the correct device and how many are needed. It is essential that the lowest point of the check is in the middle of the channel so that during heavy rain events water flows over the top of the device and not around, which will result in erosion and undermining the device.
Protecting inlets during the construction phase is a significant step in providing an effective erosion control plan. We offer several options for protecting curb and area inlets.
Sediment barriers are used primarily as temporary structures to slow stormwater runoff into streams, filter sediment, and promote stormwater infiltration. Barriers can be used in agriculture, construction, restoration, and stormwater management. The type of sediment barrier used will depend on objective, coarseness of sediment, drainage area, and water velocities. Silt fences are useful in areas with low to medium sheet flow velocities, excelsior logs, and wattles can slow more concentrated flows, and other structures like berms are used in areas with higher concentrated flow velocities. Sediment barriers are also used for perimeter protection.
Erosion Control Blankets
Erosion control blankets consist of mulch (straw, coconut, wood, plastic) sewn between two nets. The netting and thread sandwich the mulch material together and the blanket can then be rolled out and pinned to the ground with a variety of fasteners. The soil is prepared and seeded, and then blankets are rolled out and pinned in place. The life span of Erosion Blankets can range from 3-12 months (temporary) 12-36 months (long term) or permanent (TRM). 100% biodegradable blankets are also available. Turf reinforcement mats (TRM) are a permanent blanket that enables vegetation to be used in areas where the forces exerted by water or wind exceed the sheer limits of unreinforced vegetation. Typical applications include swales, storm flow zones of channels, stream banks, and extreme slopes. TRM’s are usually made from synthetic fibers, and depending on the product can be used by itself, or filled with soil or hydraulic mulch.
Straw and various types of hydro mulches are popular methods to prevent wind and water erosion. Bonded Fiber Matrixes are sprayed on and is an excellent alternative to conventional rolled erosion control blankets.
