Industrial Pit Cleaning and Sludge Removal Across Ontario

Sludge, sediment, scale and process residue reduce pit capacity, obstruct drainage and conceal the condition of concrete, steel and existing coatings. Thorough cleaning is often the first step before inspection, concrete repair or installation of a new lining.

TK Industrial Services Inc. provides industrial pit cleaning and sludge-removal support throughout Ontario. We coordinate cleaning with restoration work so pits, tanks, sumps and containment areas can move efficiently from dirty service conditions to repair and recoating.

Cleaning Industrial Pits, Sumps and Tanks

Our cleaning services can support:

• Underground concrete pits

• Process and wastewater pits

• Sumps, trenches and collection basins

• Secondary containment areas

• Industrial tanks and vessels

• Cooling tower basins

• Maintenance and shutdown cleaning

Materials may include settled solids, mud, scale, sediment, oils, process residue and non-hazardous sludge, subject to site information and an agreed handling plan.

Sludge Removal Before Inspection and Restoration

A pit cannot be properly evaluated while deterioration is covered by residue. Cleaning exposes cracks, spalling, corrosion, failed joints and delaminated coatings. It also helps determine the true repair quantities before rehabilitation begins.

Where required, the cleaning scope may involve dewatering, pumping or vac truck support, pressure washing, scraping, chipping  and removal of remaining buildup. Waste characterization, transportation and disposal responsibilities should be established before work begins.

Integrated Cleaning, Repair and Lining

TK Industrial Services can carry a project beyond cleanout. Once the substrate is exposed, our team can remove failed material, repair deteriorated concrete, abrasive-blast suitable surfaces and install the specified coating or lining.

Combining these stages under one coordinated project can reduce delays between contractors and help maintain a clear sequence from cleaning to return to service.

Scheduled Maintenance and Shutdown Cleaning

Routine pit cleaning can help maintain usable capacity and identify problems before they cause an unplanned outage. For heavier buildup or restoration work, cleaning can be incorporated into a scheduled shutdown with the necessary repair and coating activities.

Serving Industrial Sites Throughout Ontario

We support manufacturing, automotive, steel, chemical, food and beverage, water and wastewater, utility and other industrial facilities across the province.

Frequently Asked Questions

Does a pit need to be cleaned before it is relined?

Yes. Cleaning, sludge removal, concrete repairs MUST be done before a new liner or coating system is installed.

Do you dispose of the removed sludge?

Waste handling and disposal must be defined for each project based on material characterization, site responsibilities and applicable requirements. Disposal should not be assumed until the scope is confirmed.

Can pit cleaning be scheduled during a plant maintenance and

shutdown?

Yes. Cleaning is often the first activity in a shutdown restoration sequence and should be planned early enough to allow inspection and repairs afterward.
