Waterproofing and Concrete Repair Belong Together
Leaking garages, balconies, foundations, and podium slabs often include cracked or deteriorated concrete. If the substrate is weak, contaminated, or delaminated, a new membrane cannot perform for long. We address concrete condition as part of the waterproofing plan.
Common Repair Scopes
We handle crack routing and sealing, spall removal, patch repair, overhead garage repairs, slab-edge repairs, joint repairs, parging removal, and localized structural restoration. Where engineering review is required, we coordinate with the project engineer instead of guessing at structural requirements.
Chlorides and Corrosion
In parking structures, salt-laden water can reach reinforcing steel and accelerate corrosion. Repair may include removing damaged concrete, cleaning or treating reinforcement, patching with compatible repair mortar, and protecting the repaired area with a membrane or coating.
Costs Depend on Deterioration
Concrete restoration is quoted by quantity, access, depth, overhead conditions, reinforcing exposure, and engineering requirements. We identify repair areas, separate them from waterproofing costs, and explain which repairs are required before coating or membrane installation.
Structural vs Non-Structural
Not every crack is structural, and not every spall is cosmetic. We classify visible conditions and recommend engineering involvement where movement, load, reinforcing exposure, or life-safety concerns are present.
Surface Preparation
Grinding, chipping, shotblasting, cleaning, and moisture control are often the difference between a lasting repair and a patch that fails after one winter. We prepare the substrate to the repair material and membrane manufacturer's requirements.
Documentation for Owners
For condos and managed properties, we document repair locations, photos, and quantities so boards can see what was repaired and why it mattered to the waterproofing system.
Issues We Hear About Most Often
Boards, property managers, and GCs across the GTA run into the same leak patterns. Here is what usually leads to this service — and how we approach the repair.
A membrane failed over bad concrete
Coatings cannot bond to weak, wet, or contaminated concrete. Repair and surface prep need to happen first.
Garage ceilings are spalling
Overhead spalls often indicate water and chloride exposure. We remove unsound material and repair before protection is reapplied.
Nobody knows if the crack is structural
We flag conditions that need engineering review and separate structural concerns from routine waterproofing prep.
Boards need quantity documentation
Repair quantities affect budgets. We document areas and explain why each repair supports the waterproofing scope.
Concrete Restoration Across the GTA
Concrete Restoration is available across Toronto and the Greater Toronto Area. Crews are routed by region so site reviews and emergency leak calls stay practical:
