Silt Sock

Silt sock are a three-dimensional tubular sediment control and storm water runoff filtration device. Silt socks trap sediment and soluble pollutants by filtering runoff water as it passes through the matrix of the Silt sock and by allowing water to temporarily pond behind it. They are also used to reduce runoff flow velocities on sloped surfaces.

 

Silt sock are to be installed down slope of any disturbed area requiring erosion and sediment control and/ or filtration of soluble pollutants from runoff. Silt sock are effective when installed perpendicular to sheet or low concentrated flow, and in areas that silt fence is normally considered appropriate.

Concrete Sock

We have reintroduced a range of low cost treatment socks for concrete waste. The socks are a modification of the bio-sock system that is used to treat and filter sediment laden water. The addition of a reagent in the socks means that the composted filter media not only picks up the cement fines in the waste water but also now adjusts the pH to around a neutral level. The sock based system can come in varying lengths and can be used in a curb or placed in a circle so a concrete truck could drop its wash water into it to treat it. The system is versatile and can be used across most concrete operations including exposed aggregate, concrete cutting, piling and any other operation dealing with concrete.
