For more than 20 years, Soil-Tech has been helping homeowners and construction managers throughout Texas limit erosion and develop their landscapes. We do this through erosion control tactics, hydroseeding, and landscape supply. Erosion Control For construction areas of over 1 acre, contractors need a Storm Water Pollution Prevention Plan. We specialize in designing unique SWPPPs to guarantee compliance. Hydroseeding We help you fast-track your lawn growth through a nutrient-rich slurry of seeds and mulch. This anchors free dirt and limits erosion. Landscaping Materials We load and deliver bulk material for landscaping use. Products include topsoil, caliche, gravel, flagstone, sand, granite and mulch.
