Concrete Repair & Restoration
Industrial Concrete Repair & Restoration Services in Ontario
Concrete deterioration in industrial and municipal facilities is rarely an emergency until it is. Zimcoat provides a complete range of industrial concrete repair services — from crack injection and spall repair to full slab restoration and CFRP structural strengthening — designed for facilities that cannot afford unplanned downtime or prolonged disruption.
The problem industrial facility facilities face: Cracking, spalling, delamination, and joint deterioration are the most common — and most ignored — maintenance items in industrial facilities. Deferred repair accelerates deterioration, reduces structural capacity, creates trip and safety hazards, and ultimately costs significantly more to address than proactive intervention would have.
Where Zimcoat Works in Industrial Facility Facilities
Crack Repair & Injection
Epoxy injection for structural, load-bearing cracks restoring tensile strength. Flexible polyurethane injection for active or water-transmitting cracks. Both systems adaptable to vertical, overhead, and below-grade applications.
Spall & Delamination Repair
Saw-cut perimeter, remove delaminated material, prime, and apply cementitious or epoxy repair mortar to restore cross-section and re-establish bond. Matched to surrounding concrete profile.
Joint Repair & Replacement
Failed control joint and construction joint restoration using semi-rigid polyurea joint filler systems. Provides load-transferring edge support under forklift wheel loads while accommodating slab movement.
Surface Grinding & Preparation
Diamond grinding to remove surface contamination, high spots, trowel marks, and failed coatings. Essential surface preparation step for coating or overlay application and trip hazard elimination.
Concrete Overlays & Resurfacing
Polymer-modified cementitious or epoxy-based overlays that restore surface profile and functionality without full slab replacement. Available in thicknesses from 6mm to 50mm+.
CFRP Structural Strengthening
Carbon fibre reinforced polymer laminates, fabric wraps, and near-surface-mounted (NSM) bars for restoring or upgrading structural capacity of beams, slabs, columns, and walls with minimal disruption.
Concrete Repair Methods & Systems
| System | Best For |
|---|---|
| Epoxy Crack Injection | Low-viscosity structural epoxy injected under controlled pressure into dormant cracks. Restores monolithic cross-section and tensile strength. Suitable for horizontal, vertical, and overhead cracks. |
| Polyurethane Crack Injection | Flexible, hydrophilic foam or gel injection for active or water-transmitting cracks. Expands on contact with water to seal the crack. Used for live leaks in below-grade and water-retaining structures. |
| Cementitious Repair Mortars | Polymer-modified Portland cement mortars for spall and section loss repair. Rapid-set formulations available. Selected for compatibility with the specific exposure environment. |
| Epoxy Mortar Repair | High-strength epoxy-based repair mortar for chemical-exposure areas, heavily loaded surfaces, and thin section repairs requiring strength matched to surrounding concrete. |
| Semi-Rigid Polyurea Joint Filler | Poured or injected into saw-cut joints to support arris edges under wheel loads. Semi-rigid formulation balances joint movement accommodation with edge support. |
| CFRP Laminates & Wraps | Externally bonded carbon fibre systems for structural rehabilitation. Dramatically increases flexural, shear, and confinement capacity of existing members. Designed by structural engineer. |
What a Facility Assessment Includes
- Comprehensive facility walk-through with facility manager or capital project lead
- Visual concrete condition survey: crack mapping, spall identification, joint condition rating
- Non-destructive testing as required: hammer sounding, pull-off adhesion testing, moisture content
- Structural review for areas with apparent capacity concerns
- Emergency vs. planned repair prioritization discussion
- Written scope with repair methods, material specifications, and budget estimate
Common Questions from Industrial Facility Facility Teams
- How do I know if I need emergency repair or if it can be planned?
- Signs that warrant immediate attention include: active cracking with vertical displacement (slab movement), delaminated areas directly in forklift or vehicle paths, cracked or spalled areas over rebar with evidence of corrosion, and any structural cracking in walls, columns, or overhead slabs. Surface spalling without structural implication can usually be scheduled into planned maintenance windows. We help you prioritize during the assessment.
- How do I know if my concrete can be repaired or needs replacement?
- Concrete that has adequate residual tensile strength, sufficient cover depth over rebar, and limited carbonation depth is generally a good repair candidate. Where corrosion has progressed extensively, cover is lost over a large area, or the base slab has insufficient strength to bond to, replacement may be more cost-effective. We assess this objectively and give you both options where applicable.
- Should I repair the concrete before or after applying a coating?
- Always before. Coatings applied over unsound, cracked, or deteriorated concrete will delaminate at the weakest point. Our standard process is: assess condition, complete all required concrete repair, verify surface preparation, then apply the coating system. This sequence is non-negotiable for a long-term result.
- What warranty do you provide on concrete repairs?
- Warranty terms depend on the repair method, exposure conditions, and preparation quality. We provide written warranty for workmanship and material performance on all projects. We will explain the specific warranty coverage for your scope during the estimate process.
