Our Envirotac line of erosion control polymers works great to protect slopes and embankments from Erosion. Envirotac being an acrylic polymer will penetrate the earth soil and upon curing will bond the soil particles together. This will "laminate" the area reducing water and wind penetration keeping soil sediment in place. Unlike mulch applications, it will not sheet off but will stay adhered to the soil. Also it will not harm vegetation and in many instances will increase germination rates.
