Polyurethane Grout Injection is a cutting-edge, non-invasive method for permanently stopping active water leaks and stabilizing compromised concrete structures. By injecting a specialized, low-viscosity liquid resin into cracks, voids, and construction joints, we create a flexible, durable, and watertight barrier.

This technology is the ideal alternative to costly, time-consuming excavation and replacement.

Core Benefits

• Stops Active Leaks Instantly: The grout is hydro-active (water-activated) and reacts immediately upon contact with moisture, expanding up to 40 times its volume to create an immediate and permanent seal, even against gushing water.

• Flexibility and Durability: Unlike rigid materials like epoxy, cured polyurethane forms an elastomeric (flexible) seal. This allows the concrete structure to endure normal expansion, contraction, and minor ground movement without re-cracking the repair.

• Speed and Efficiency: The injection process is quick, clean, and requires minimal drilling. The material cures rapidly—often within minutes—allowing the structure to be returned to service with virtually no downtime.

• Non-Invasive: Repairs are executed from the inside, eliminating the need for exterior excavation, digging, and costly disruption to landscaping, decks, or sidewalks.

• Deep Penetration: The low viscosity of the resin allows it to penetrate deep into fine and hairline cracks, ensuring a thorough, comprehensive seal that traditional patching cannot match.

Ideal Use Cases

We utilize Polyurethane Grout Injection for a wide range of critical applications:

• Basement Waterproofing: Sealing cracks and pipe penetrations in foundation walls to prevent water seepage and moisture damage.

• Below-Grade Structures: Waterproofing tunnels, vaults, manholes, and underground utility corridors.

• Structural Void Filling: Filling large voids beneath concrete slabs (slabjacking) to stabilize settling and level uneven floors with a lightweight, strong material.

• Water-Holding Structures: Repairing leaks in water reservoirs, storage tanks, and swimming pools.

• Soil Stabilization: Injecting into loose or sandy soils around foundations to consolidate and strengthen the ground, preventing future settlement.

Surface refinement services including sacking (filling minor defects and bug holes with cement slurry) and parging (applying a protective, smooth mortar coat to vertical surfaces). This includes hydraulic cement application for waterproofing purposes.

Utilizing Ground Penetrating Radar (GPR) to accurately locate high-voltage wires, rebar, and plumbing within concrete structures to ensure safety and prevent incidents that could damage your investment.
