Chemical Grouting - I and I Remediation

Water infiltration and inflow is a huge and growing problem for municipalities and others responsible for operating limited capacity treatment plants. One of NWCW’s core competencies includes I&I mitigation work. We provide the following injection repairs for structural concrete:

  • chemical injection crack repairs for wet surfaces
  • flexible, water-activated grout pumped from inside a structure where external excavation is impossible for access or expense reasons
  • epoxy crack filler for dry substrates or to re-bond cracked structures before coverage with high-strength grout and/or protective coatings
  • We will perform these services on brick-and-mortar manholes as well as concrete assets
