Your purchase of the ESS-13 Spray-On formulation includes on-site technical representation during the installation process by an SCI Installation Specialist. The ESS-13 Spray-On application is most effective if applied during a rain-free period from the start of the project until the pond is full. Temperatures during the entire sub-grade preparation and installation need to be above freezing.
The following are our basic instructions. Please consult with your sales rep for more specific information pertaining to your project.
The sub-grade shall be free of rock outcrops or other foreign debris. Any areas that are predominantly sand or gravel should be over-excavated by a minimum of six inches and replaced with an approved soil.
The ESS-13 Spray-on application is most easily applied with a water truck, but other spray equipment is acceptable. The product will arrive on-site in 55-gallon drums. The product should be transferred from the drums into the water truck under the direction of the on-site Seepage Control Field Representative. The product should then be sprayed on to the prepared sub-grade starting at the top of the slope, working downward. It is important that the spray is uniform, covers the entire area, and is not at a rate that causes erosion. The product is to be applied in repeated light applications that build on each other. Once the sub-grade is thoroughly covered, the application is complete.
The sprayed-on liner should be allowed to air dry for 1 to 3 days, depending on weather conditions.
It is then covered with a layer of moisturized and compacted soil.
