Targeted High-Pressure Injection for Active Water Ingress in Concrete Structures
Targeted injection repair of active leakage pathways in below-grade concrete structures.
Active Water Ingress: Identification, Pathway Analysis & Targeted Control
High-Pressure Crack Injection
Targeted sealing of structural cracks in below-grade concrete using controlled, high-pressure injection.
Resin is delivered through installed packers to achieve full-depth penetration and permanent sealing at the defined leakage pathway—without excavation or unnecessary scope expansion.
Ideal use cases: Underground parkades, foundation walls, slab-on-grade structures, elevator pits.
Active Leak Pathway Sealing
Targeted injection to arrest active water infiltration at cracks, cold joints, and localized defects.
Hydrophilic polyurethane resins react in the presence of moisture to form a watertight internal seal.
Ideal use cases: Active leakage points, expansion joints, service penetrations, parkade seepage.
Expansion & Construction Joints
Targeted injection sealing of construction and movement joints subject to active water ingress.
Resin is delivered under controlled pressure at defined leakage pathways to form a continuous, flexible seal that accommodates thermal movement and minor structural displacement—maintaining watertight continuity along the joint.
Ideal use cases: Expansion gaps, construction joints, podium slabs, below-grade joint systems.
Parkade Soffit & Wall Injection
Targeted overhead (soffit) and vertical injection to seal active water ingress in suspended slabs and foundation walls.
Controlled resin delivery at defined leakage pathways limits moisture and chloride ingress, protecting embedded reinforcing steel and maintaining long-term durability of the concrete assembly.
Ideal applications: Overhead slab soffits and vertical wall assemblies within underground parkade structures.
High-pressure injection provides controlled, targeted sealing of active water ingress in below-grade concrete—delivering durable, minimally disruptive repair without unnecessary scope expansion.

Active Water Ingress – Identification & Control
Efflorescence – Indicator of Active Moisture Migration
Mineral deposition indicating moisture movement through the concrete matrix, often evidencing active water ingress and subsurface leakage pathways.
Significance
• Indicates active moisture migration through the concrete matrix
• Suggests presence of subsurface ingress pathways
• Often associated with slab-level or low-elevation
leakage zones
Structural Crack – Active Ingress Pathway
Movement-related cracking providing a continuous pathway for water ingress through the concrete element.
Significance
• Through-depth or near full-depth (continuous) pathway
• Represents a primary conduit for water ingress
• May lead to:
– Ongoing leakage
– Chloride ingress
– Reinforcement corrosion over time
Function of Injection
• Seals active leakage pathways at cracks, joints, and interfaces
• Restores continuity of the concrete barrier
• Limits moisture and chloride ingress to protect embedded reinforcing steel
• Seals active leakage pathways at cracks, joints, and interfaces
• Restores continuity of the concrete barrier
• Limits moisture and chloride ingress to protect embedded reinforcing steel
