Mainstay® ML-72HP™ Horizontal Pipe Restoration Mortar


ML-72HP is a reinforced blend of Portland cement, micro silica, densifiers, admixtures, and other modifiers that produces a high strength and low permeability mortar specifically designed for centrifugal application within underground concrete, brick and galvanized corrugated metal pipe (CMP). MAINSTAY ML-72HP provides a uniform, waterproof surface that is extremely dense, abrasion resistant and highly impermeable, while providing excellent adhesion to the substrate. With superior compressive, flexural and tensile strengths, MAINSTAY ML-72HP can help restore structural integrity to deteriorated underground concrete and corrugated metal pipe quickly and economically.
