Grout Injection Services & Active Water Leak Repair

Active water leaks can damage equipment, increase wastewater treatment loads and accelerate concrete deterioration. Banks Industrial Group seals leaking cracks, joints and pipe penetrations in concrete tanks, manholes, vaults and other industrial structures throughout New Jersey, Pennsylvania, Delaware and New York.

BIG uses polyurethane chemical grout injection to control active leaks quickly and help extend structure service life. When deterioration extends beyond the leak, our crews can combine leak sealing with concrete restoration, protective coatings or epoxy injection for suitable dormant structural cracks.

Concrete Grout Injection Services:

  • Active leak repair using hydrophilic polyurethane crack injection
  • Seal cracks caused by shrinkage, settlement and freeze/thaw cycling
  • Manhole leak sealing and curtain wall grouting to prevent infiltration and inflow
  • Soil stabilization for concrete structures using hydrophobic polyurethane grout injection
  • Epoxy injection for suitable dormant structural cracks
  • Expert consultation to match the best repair method to crack characteristics

Benefits of Concrete Leak Injection:

  • Stop active leaks: Seal water pathways through cracks, joints and pipe penetrations
  • Extend asset life: Preserve serviceable structures and help defer costly replacement
  • Reduce operating costs: Limit water loss and unwanted groundwater entering wastewater systems
  • Minimize disruption: Fast-curing grouts help shorten repair time
  • Avoid tank draining: Suitable leaks can be repaired while tanks remain filled and operating
  • Reduce excavation: Accessible leaks can often be sealed without digging
  • Accommodate crack movement: Flexible grouts maintain seal as cracks expand and contract
  • Slow water-related deterioration: Limit moisture intrusion that contributes to corrosion and freeze/thaw damage

Concrete leak injection seals water pathways through cracks, joints and penetrations. For machinery baseplates, equipment foundations and load-transfer grouting, see BIG’s Industrial Grouting Services.

Why Hire Banks Industrial Group?

Effective leak repair takes more than selecting a grout. BIG combines material selection, hands-on installation and industrial safety practices to deliver repairs suited to your facility.

  1. Expertise matched to your problem
    We assess crack characteristics, movement, water flow and exposure conditions to recommend an appropriate repair.
  2. Safety suited to industrial work
    BIG brings confined-space training, OSHA 30 training and ISNetworld A+ RAVS+ qualifications that help meet facility requirements and support safe execution.
  3. Repairs planned around your operations
    We coordinate access, installation and curing requirements with your team to minimize disruption and support a timely return to service.
  4. Leak sealing and restoration together
    When damage extends beyond the leak, BIG can rebuild deteriorated concrete and apply protective coatings, including Belzona systems. One contractor coordinates the work to support durable repairs and protection against future deterioration.
concrete crack leak repair in water tank

Seal Concrete Tank Cracks Without Draining

Settlement, freeze/thaw cycles and vibration can crack concrete tanks, causing water loss and deterioration. BIG injects selected flexible polyurethane grout from the accessible exterior to seal suitable non-structural cracks while tanks remain filled and operating. The flexible grout helps keep the crack watertight as the concrete expands and contracts. Sealing the leak helps slow deterioration and extend tank service life, while repairing the tank without draining reduces downtime and associated costs. See our Concrete Tank Repair page for complete services.

concrete crack leak repair in manhole

Seal Concrete Manhole Cracks to Reduce Infiltration

Cracks and failed joints in concrete manholes let groundwater enter sewer systems, increasing treatment costs and straining capacity during storms. BIG injects selected polyurethane grout to seal leaking cracks, joints and pipe penetrations, using flexible materials where movement is expected. Reducing infiltration helps lower treatment costs, preserve sewer capacity and reduce overflow risk. Repairs can often be completed from inside the manhole without excavation, limiting disruption and helping extend structure service life. See our Wastewater Treatment Plant Solutions page for complete services.

Seal Leaking Cracks in Underground Concrete Vaults

Groundwater leaking through cracks and joints in underground concrete vaults and structures can damage equipment, create safety hazards and accelerate deterioration. BIG injects selected polyurethane grout to seal active leaks in cracks, joints and pipe penetrations. Suitable repairs can be performed from inside the structure without excavation, reducing costs and site disruption. Sealing water pathways helps protect equipment, slow concrete deterioration and extend structure service life. See our complete set of Industrial Concrete Repair Services here.
