V-1 Grout is composed of graded sieve sizes of pure silica sand, high early cement, plus natural inorganic and synthetic materials, blended under strict quality control standards for consistent, uniform, high quality. Finished appearance is similar to concrete.
Volumetric expansion occurs within 24 hours after mixing with water. Thereafter V-1 becomes completely stable, neither shrinking nor expanding. The limited expansion and internal pressure development are achieved by a high-density crystal formation during hydration.
