Injection grouting, end to end
We seal active water ingress at the source — in sewers and pipes, below-grade foundations, sumps, and structures. Every method is matched to the conditions and verified on completion.
Sewer & Storm Mains
TrenchlessLive-flowChemical grout injection seals infiltration at joints, laterals, and cracks in live mains — no excavation, minimal flow disruption.
Foundation Waterproofing
Below-gradePU resinNegative-side polyurethane injection stops active leaks through cracks and cold joints in below-grade walls and slabs.
Sumps & Elevator Pits
AcrylateSealingPermanent water cut-off for pits, mechanical rooms, and reservoirs where standing water threatens equipment.
Manhole & Chamber Rehab
RehabI&I controlSeal leaking structures, benches, and pipe penetrations to restore watertight integrity and stop I&I.
Pipe Joint & Lateral Sealing
CCTV-verifiedTest-and-seal joint grouting for pressurized and gravity pipe, with CCTV verification on every pass.
Curtain & Permeation Grouting
GeotechnicalSoil stabilization and water cut-off curtains injected behind structures and around penetrations.
Marine & Underwater Grouting
Dive-supportedWaterfrontBacked by Fraser Burrard’s commercial dive teams — sealing seawalls, intakes, outfalls, and submerged structures from the waterline down.
Sealed from the inside — no dig, no shutdown
Most leaks can be stopped without excavation. We inject resin directly at the defect, expanding to fill the void and cure into a permanent, flexible seal — often while the line stays in service.
Where grouting meets the waterline
Our grouting division is backed by Fraser Burrard Diving’s commercial dive teams — over 50 years of work in strong current, zero visibility, and cold water to depths past 50 metres. That reach lets us seal what land-based crews can’t: seawalls and abutments, intake and outfall structures, dam faces, and submerged joints and penetrations.
