Hybrid cementitious grout outguns epoxy-based formulations

Company has engineered a versatile grout material for supporting machinery and applications requiring precision alignment. The cement-based, nonmetallic, non-shrink Hybrid Grout develops compressive strengths that rival epoxy-based grouts without the added expense. Formulated with the Five Star Air Release Technology to increase durability of the hardened concrete, it offers a 95 percent effective bearing area, meaning less voids and a better bond. The material’s smooth consistency results in optimal flowability for pumping or pours.
