Concrete Pit and Tank Linings Across Ontario

Unprotected or poorly coated concrete can absorb moisture and chemicals through pores, cracks, joints and surface defects. Over time, this exposure may lead to softening, spalling, leakage, reinforcement corrosion and loss of serviceability.

TK Industrial Services Inc. repairs and lines industrial concrete tanks, process pits, waste pits, sumps and basins throughout Ontario. Our work combines substrate rehabilitation with protective coating systems designed for the conditions inside the structure.

Protective Linings for Concrete Immersion and Process Areas

Concrete pit and tank linings can provide a protective barrier between the substrate and the contained liquid or process environment. Potential applications include:

• Wastewater and process-water tanks

• Chemical and waste pits

• Sumps and collection basins

• Treatment tanks and clarifiers

• Concrete containment areas

• Pulp, paper, steel and manufacturing pits

• Food and beverage process areas

Why Concrete Preparation Matters

Concrete is variable and porous. Its surface may contain debris, contamination, previous coatings or chemically weakened material. Moisture may also be moving through the structure. These conditions must be considered before installing a new lining.

Preparation can include pressure washing, abrasive blasting, mechanical preparation, removal of unsound concrete and old coatings, crack repair, void filling and resurfacing. The objective is to expose a clean, sound and appropriately profiled substrate.

Concrete Tank Coating and Lining Systems

The correct lining is determined by the tank’s service conditions. TK Industrial Services can install specified epoxy, novolac, vinyl ester and fiberglass-reinforced systems for suitable applications. Key selection factors include:

• Chemical composition and concentration

• Continuous immersion or intermittent exposure

• Operating and cleaning temperatures

• Abrasion, flow and impact

• Existing moisture conditions

• Required return-to-service time

• Food, potable-water or other project-specific requirements

Our Concrete Pit and Tank Lining Process

1. Review the structure, exposure and operating requirements

2. Remove sludge, residue and contamination

3. Strip failed coatings and weak concrete

4. Repair cracks, bugholes/pinholes, joints and damaged sections

5. Resurface irregular areas where necessary

6. Apply the compatible primer and lining system

7. Complete specified quality checks and cure before service

Relining Existing Concrete Assets

A deteriorated lining does not always mean the tank or pit must be replaced. When the underlying concrete can be restored, relining may provide a practical way to extend asset life and reduce the disruption associated with demolition and reconstruction.

Ontario Concrete Lining Contractor

TK Industrial Services works with facility managers, engineers, general contractors and maintenance teams across Ontario. We can coordinate lining work with plant shutdowns and combine it with pit cleaning, sludge removal and concrete rehabilitation.

Frequently Asked Questions

Can you coat over an existing concrete tank lining?

Only after its condition and compatibility are evaluated. Loose, contaminated or incompatible material must be removed before a new system is installed.

Can cracks be repaired before lining?

Yes. Cracks, voids and deteriorated areas should be addressed as part of substrate preparation. The appropriate repair depends on the type and cause of movement.

What information is needed for a quote?

Useful information includes dimensions, drawings, photographs, access points, tank contents, temperatures, current coating condition and the available shutdown window.

After all is addressed a subsequent site visit and substrate evaluation can be scheduled.

Industrial Concrete Rehabilitation

Industrial Concrete Rehabilitation Across Ontario

Industrial concrete is exposed to conditions far beyond ordinary building use. Chemicals, constant moisture, heat, vibration, abrasion, heavy traffic and freeze-thaw cycling can damage slabs, pits, tanks, curbs, walls and containment structures.

TK Industrial Services Inc. provides industrial concrete rehabilitation throughout Ontario. We remove failed material, rebuild deteriorated areas and prepare restored surfaces for protective coatings or linings for coating bonding.

Repair Concrete Before Damage Spreads

Early deterioration can develop into deeper structural and operational problems when liquids reach reinforcing steel or chemicals continue attacking the substrate. Warning signs include:

• Cracks, delamination and spalling

• Soft, eroded or chemically attacked surfaces

• Exposed aggregate or reinforcing steel

• Broken edges, curbs and equipment bases

• Leaking pits and tanks

• Loose previous repairs

• Coating failure caused by weak underlying concrete

Concrete Restoration for Industrial Facilities

Our concrete rehabilitation work can support:

• Process and wastewater pits

• Concrete tanks and basins

• Secondary containment structures

• Manufacturing and warehouse areas

• Equipment pads and foundations

• Curbs, trenches and channels

• Walls, floors and other plant structures

Industrial Concrete Repair Process

Each project begins by identifying the limits of unsound material and the intended service conditions. A typical scope may include:

1. Cleaning and exposing the damaged area

2. Removing loose, contaminated or weakened concrete

3. Preparing sound edges and the repair surface

4. Addressing exposed reinforcement where included in the scope

5. Rebuilding the area with compatible industrial repair materials

6. Resurfacing transitions and irregular sections

7. Applying a protective coating or lining where specified

Rehabilitation Before Protective Coating

Protective coatings perform best when installed over a stable substrate. Filling only visible holes while leaving surrounding weak material in place can transfer the failure to the new repair boundary. TK Industrial Services work to remove concrete, rebuild and coat to create a consistent restoration system.

Planned and Shutdown Concrete Repairs

Industrial concrete rehabilitation can be completed as a stand-alone project or incorporated into a broader outage. Combining cleaning, concrete repair and coating installation under a planned shutdown can reduce repeated mobilization and simplify coordination between trades.

Serving Industrial Facilities Across Ontario

We support manufacturing, steel, chemical processing, food and beverage, power, water and wastewater, mining and other industrial operations throughout Ontario.

Frequently Asked Questions

Is concrete rehabilitation different from applying a coating?

Yes. Rehabilitation restores damaged or unsound concrete. A coating or lining then protects the restored substrate when the application requires it.

Can chemically damaged concrete be repaired?

In many situations, damaged material can be removed back to sound concrete and rebuilt. The exposure and remaining substrate condition must be evaluated before selecting repair materials.

Can concrete repair and lining be handled in one scope?

Yes. Combining the work improves coordination and helps ensure the repair materials, surface preparation, primer and lining are compatible.

Structural Steel Coatings for Ontario Industry

Corrosion on structural steel can spread across beams, columns, platforms and overhead crane structures, particularly in facilities exposed to humidity, chemicals, washdown, dust or temperature changes. Peeling paint and surface rust also make maintenance more difficult and can allow deterioration to progress unnoticed.

TK Industrial Services Inc. provides surface preparation and protective coating services for industrial structural steel across Ontario. We work around plant access, production schedules and shutdown windows to restore coating protection on difficult industrial structures.

Protective Coatings for Beams and Plant Steel

Our structural coating services can be used on:

• Structural beams and columns

• Overhead crane bridges and supporting steel

• Mezzanines, platforms and catwalks

• Equipment supports and pipe racks

• Handrails, ladders and access structures

• Exterior plant steel and industrial frameworks

• Structural components in corrosive process areas

Surface Preparation Drives Coating Performance

New paint cannot compensate for poor preparation. Rust, mill scale, loose coatings, salts, dust, grease and embedded contamination can interfere with adhesion. Depending on the project specification and access, preparation may include cleaning, abrasive blasting, power-tool preparation and detailed work around connections, edges, bolts and welds.

Prepared surfaces are then coated with a system suited to the exposure, required durability and operating environment.

Coating Systems for Industrial Exposure

Structural coating systems may include compatible primers, high-build epoxies and durable finish coats. Selection depends on whether the steel is indoors or outdoors, the severity of corrosion, chemical exposure, UV exposure, temperature, abrasion and the facility’s maintenance objectives.

TK Industrial Services follows the approved product data and project specification for surface preparation, application conditions, recoat intervals and curing.

Overhead Structural Crane Coatings

Overhead crane structures create unique access and coordination requirements. Coating work may need to account for crane availability, electrical and mechanical components, active production areas and overhead containment. TK Industrial Services can plan the work with plant personnel and other trades during a scheduled maintenance period or shutdown.

Structural Coating Maintenance

Not every facility needs to wait for widespread coating failure. Periodic inspection and targeted maintenance can address localized corrosion before it expands. Maintenance scopes can include cleaning, spot preparation, stripe coating of edges and connections, and full recoating where required.

Ontario-Wide Industrial Coating Service

We serve manufacturing plants, steel facilities, automotive operations, utilities, warehouses, processing plants and other industrial sites across Ontario.

Frequently Asked Questions

Can structural steel be coated without stopping the entire plant?

Sometimes. The answer depends on access, containment, nearby operations and the coating specification. Work can often be phased or coordinated with specific production outages.

Do you coat overhead crane structures?

Yes. TK Industrial Services can prepare and coat overhead crane structures and related supporting steel, subject to access and project requirements.

Can you remove the old structural coating?

Yes. Failed coatings and corrosion can be removed using the preparation method specified for the project, including abrasive blasting where appropriate.
