The GeoSpray® 61 spray-applied liner system is a high-performance, fiber-reinforced mortar specifically designed for corrosion prevention and structural enhancement of pipes in drinking water applications. This high-strength, ultra-low porosity material is made from natural mineral polymers and recycled industrial waste streams. The GeoSpray 61 system is designed for multiple application techniques, including pouring, placing, troweling, spraying, and centrifugal casting.
