Common Leakage Issues & Injection Workflow
Active water ingress in below-grade concrete structures is typically localized at cracks, cold joints, and slab–wall interfaces.
DBTI applies targeted high-pressure injection to seal defined leakage pathways without excavation or unnecessary scope expansion.
Common Water Ingress Conditions in Concrete Structures
Underground Parking Structures
Active leakage in parkades is typically associated with failed expansion joints, slab cracks, and wall–slab interfaces.
Foundation Cracks
Shrinkage and settlement cracks create defined pathways for groundwater infiltration within below-grade concrete.
Warning Signs & Risks
Efflorescence, damp staining, and active seepage indicate moisture movement that may lead to rebar corrosion and localized deterioration.
Step 01
Professional Inspection
Targeted evaluation of active water ingress within below-grade concrete structures.
Flow patterns and hydrostatic pressure are assessed to identify defined leakage pathways and confirm injection scope.
Step 02
Injection Preparation
Injection ports (packers) are installed at calculated intervals along identified ingress pathways.
Preparation is critical to ensure controlled resin delivery and full-depth penetration within the affected area.
Step 03
High-Pressure Injection
High-pressure injection is performed using hydrophilic polyurethane resins delivered through installed packers at controlled pressures.
The material reacts with moisture within active leakage pathways to form a durable seal, arresting water ingress at the point of entry.
Step 04
Quality Follow-up
Following injection, packers are removed and all entry points are patched to restore surface continuity.
A final inspection confirms the effectiveness of the repair and verifies that active leakage has been controlled.
