Chemical Grouts

Avanti International injection grouts

Infiltration enters underground systems every day through defects or faulty joints in manholes, causing system capacity issues, overload at treatment plants and possible injury to the community. Avanti International injection grouts have historically proven to be an economic and long-term solution to combating infiltration entering all areas of a collections system, including manholes. Injection grouts are engineered to stop leaks, stabilize soil and control groundwater, and be used in precast barrel joints, brick and concrete masonry units, pipe penetrations, vertical or horizontal cracks, voids and pinholes. Each technique enables the technician to stop several leaks at once and helps to extend the life of the structure. 800-877-2570; www.avantigrout.com

Prime Resins SoiLok MH

SoiLok MH from Prime Resins is an extremely thin two-component liquid resin designed specifically for manhole applications. It is a soil binding system (a subterranean grout) used to stabilize and bind loose soil or sand, stop underground water flows and seal weeping leaks in manholes and other below-grade structures. It is an easy-to-use, premeasured kit, resulting in predictable set times in noncohesive soils. It has super-low viscosity, nearly as thin as water, allowing for thorough permeation. It contains no suspended solids in the blended product, which means no airborne particulates. It has adjustable gel set times for various site conditions. Achievable compressive strengths are site-specific and strongly dependent on sand/soil conditions, composition and particle size distribution. 800-321-7212; www.primeresins.com
