High-Pressure Crack Injection
Active Leak Repair
Controlled injection procedures for active water infiltration at cracks, cold joints, and construction interfaces.
Leaks are addressed at the point of ingress using hydrophilic polyurethane resins designed to react in the presence of moisture and form a durable seal.
Execution prioritizes localized treatment, minimal disruption in occupied structures, and prevention of further moisture and chloride ingress.
Targeted injection of cracks and localized defects in below-grade concrete elements, including foundation walls and suspended slabs (soffits), subject to active water ingress.
High-pressure delivery enables full-depth penetration and effective sealing of discontinuities without reliance on excavation.
Application is limited to defined leak pathways to maintain scope control and avoid unnecessary intervention.
Expansion & Construction Joints
Injection sealing of construction and movement joints at below-grade interfaces. Maintains water barrier continuity under thermal cycling and minor structural movement.
Parkade Soffit & Wall Water Ingress Repair
Parkade Soffit & Wall Injection Repair to arrest active water ingress, limit chloride intrusion, and mitigate corrosion risk to embedded reinforcing steel while maintaining serviceability of the structure.
Below-Grade Waterproofing | Est. 1997
Durham Basement Technologies Inc. (DBTI), established in 1997, provides below-grade waterproofing solutions for concrete structures across residential, commercial, and multi-unit properties.
Early work included exterior excavation, perimeter drainage (weeping tile), and foundation membrane systems—providing direct exposure to subsurface conditions and below-grade building envelope performance.
Additional experience includes underground piercing (directional boring) and work in constrained-access environments with complex soil and structural conditions.
Since 2017, DBTI has specialized in high-pressure injection for active water ingress in structural concrete elements, including parkade slabs (soffits), foundation walls, and construction joints.
Work is performed using controlled, targeted injection methods to arrest water ingress at the point of entry while minimizing disruption in occupied environments.
Injection systems are selected based on site conditions, including active leakage, joint movement, and substrate characteristics, ensuring effective sealing and long-term performance.
Focus is placed on limiting chloride and moisture ingress to mitigate deterioration of embedded reinforcing steel and maintain structural durability.
Serving the Greater Toronto Area
Durham Basement Technologies Inc. (DBTI) serves the Eastern Greater Toronto Area—from Yonge Street east through Durham Region to Cobourg/Clarington.
Coverage extends from the Highway 407 corridor in the north to the Lake Ontario shoreline in the south, supporting below-grade concrete structures across the region.
