The grout point manifold assembly allows the operator to pressure grout subsurface concrete structures (e.g. manholes, tunnels, basements, etc). The assembly consists of a stainless steel, tapered grout point and a mixing manifold with stainless steel ball valves and flexible connector hoses. The assembly is equipped with quick-release connectors so that it may be connected to the grout hose. The grout point is designed to insert into a 1/2" drilled hole and, when properly seated, can maintain a seal at the maximum grout pump pressure.
