Chapter 4-Site-Specific /ndustriftorm Water BMPs • <br />Chemica( ;Stabilization • <br />What Is It ' <br />Chemical stabilization practices, often referred to as a chemical mulch, soil binder, or soil palliative, <br />are temporary erosion control practices. Materials made of vinyl, asphalt, or rubber are sprayed <br />onto the surface of the soil to hold the soil in place and protect against erosion from storm water <br />runoff and wind. Many of the products used for chemical stabilization are human-made, and many <br />different products are on the market. <br />When and Where to Use It <br />Chemical stabilization can be used as an alternative in areas where temporary seeding practices <br />cannot be used because of the season or climate. It can provide immediate, effective, and <br />inexpensive erosion control anywhere erosion is occurring on a site. <br />What to Consider <br />The application rates and procedures recommended by the manufacturer of a chemical stabilization <br />product should be followed as closely as possible to prevent the products from forming ponds and <br />from creating large areas where moisture cannot get through. <br />• <br />Advantages of Chemical Stabilization <br />• Is easily applied to the surface of the soil <br />• is effective in stabilizing areas where plants will not grow <br />• Provides immediate protection to soils that are in danger of erosion <br />Disadvantages of Chemical Stabilization <br />• Can create impervious surfaces (where water cannot get through), which may in turn <br />increase the amount and speed of storm water runoff <br />• May cause harmful effects on water quality if not used correctly <br />• Is usually more expensive than vegetative cover <br />• <br />4-68
