Secondary Containment Restoration Across Ontario

Secondary containment is only effective when its concrete, joints, penetrations and protective lining remain intact. Cracks, spalling, exposed aggregate and failed coatings can create pathways through which spilled liquids may escape the containment area.

TK Industrial Services Inc. restores underground concrete pits, containment basins, curbs, bunds and tank-farm containment areas throughout Ontario. We combine cleaning, concrete rehabilitation, surface preparation and protective lining installation to return deteriorated containment structures to service.

Restore Deteriorated Underground Concrete Pits

Underground pits operate in difficult conditions. Standing liquids, chemicals, impact, abrasion, freeze-thaw cycles and constant moisture can progressively damage the concrete. Coating failure may also conceal weak or contaminated material beneath the surface.

Common problems include:

• Cracked or spalled concrete

• Exposed aggregate and reinforcing steel

• Failed joints and penetrations

• Delaminating or blistered coatings

• Chemical attack and surface softening

• Leaks or visible moisture intrusion

• Sludge and residue that prevent proper inspection

Secondary Containment Repair and Lining Process

The project scope is developed around the actual condition of the containment area and the substances it may need to hold. Work can include:

1. Removing liquids, sludge and accumulated debris

2. Cleaning the pit or containment surface

3. Removing failed coatings and unsound concrete

4. Repairing cracks, voids, transitions and deteriorated sections

5. Preparing the sound substrate for adhesion

6. Trowel on lining system (chemically bonding reinforces polymer & epoxy concretes)

7. Priming and applying the specified containment lining

8. Inspecting accessible surfaces before return to service

Chemical-Resistant Containment Coatings

A secondary-containment coating must be selected for the anticipated spill exposure—not simply for colour or general durability. Chemical type, concentration, temperature, exposure time, substrate moisture and movement at joints all affect system selection.

TK Industrial Services can install industrial epoxy, novolac, vinyl ester, fiberglass-reinforced and other specified systems where appropriate. We coordinate the repair materials, primer and lining so that each layer functions as part of one compatible system.

Applications Across Ontario

Our containment restoration services are suited to:

• Chemical storage and processing areas

• Tank farms and bulk-storage facilities

• Manufacturing and automotive plants

• Water and wastewater facilities

• Underground process and waste pits

• Loading, unloading and transfer areas

• Utility and power-generation sites

Restore the Entire Containment System

Coating over visibly damaged concrete does not correct the underlying weakness. TK Industrial Services addresses cleaning, substrate repair and lining as one coordinated restoration scope. This creates a sounder foundation for long-term coating performance.

Send our team photographs, drawings, dimensions, known chemical exposure, access restrictions and the desired maintenance window. We provide secondary containment restoration services for industrial facilities across Ontario.

Frequently Asked Questions

Can a badly deteriorated concrete containment pit be restored?

Often it can, but loose and chemically damaged material must be removed until a sound substrate is reached. The required repair depth and lining specification depend on site conditions.

Do pits need to be cleaned before restoration?

Yes. Liquids, sludge, oils, salts and other contamination can prevent inspection and compromise adhesion. Cleaning is an important first stage of the restoration scope.

How is a containment lining selected?

Selection should consider the contained chemicals, likely exposure duration, temperature, concrete condition, moisture and project schedule.
