New proprietary products in three areas of siltation and erosion control were evaluated. Hold/Gro and Griffnet materials were evaluated for use as slope stabilizers and were compared with the Department's present method of straw tacked with an asphalt emulsion. Griffolyn T-55 was evaluated for use in the construction of downdrains, and was compared with polyethylene, the material commonly used by the Department for that purpose. Poly-filter X was evaluated against the system of straw bales or brush barriers presently used to retain silt on a construction project. The report presents recommendations concerning the Department's possible use of the proprietary materials.
