Designed for sealing active water leaks in large cracks or joints in concrete structures, it can absorb up to 12 times its weight in water creating a tough, impermeable foam or gel with superb adhesive qualities. AV-202 Multigrout is certified by UL for NSF/ANSI 61 - Drinking Water System Components.
Fiberglass Hole Formers are available for manholes, straight wall structures, and for offset holes in lift stations and wet wells. Sizes from 8′′ to 56′′ diameters in a variety of wall thicknesses. Also available with high-strength magnets for convenient mounting to form cores.
Interchangeable high strength magnets together with a fiberglass hole former shell provides the fastest and easiest way to hold hole former's in place; saving time and money. Magnets are easily transferred from one hole former to another, reducing the number needed. Each magnet has more than 300 pounds of force for secure mounting of hole former's.
