Intended Use
Soil Guard has been designed to control superficial erosion caused by wind or falling rain on the treated area. Soil Guard controls erosion until permanent stabilizing vegetation can be established in disturbed areas commonly associated with state, county, or city D.O.T., Corps of Engineers/flood control, landfills, water retention ponds, landscaping, retaining wall structures, pipe and cable trenching, ski areas, golf courses, home lawns, and wetlands.
Non-Intended Use
- The prevention of landslides on soils that display deep seated instabilities or that are subject to survace peeling or frost heave.
- Extended or permanent erosion control in non-vegetative applications
- As a channel liner or in areas where poor site design concentrates overland water flow.
