Project Specifications:

• Location: Burlington, Ontario (Halton Region)

• Asset Type: Anaerobic Sludge Digester Tanks / Support Columns

• Core Issue: Structural concrete cracking on two major support columns

• Methodology: Advanced Structural Structural Concrete Repair & Specialized Injection

Tarpon Contracting’s Core Contributions:

Executing repairs on active municipal anaerobic digesters demands rigorous safety measures and precise technical delivery. Tarpon Contracting’s specialized teams managed:

​

• Targeted Defect Mapping: Conducted meticulous surface preparation and localized mapping to identify the full depth and travel of the crack networks across both columns.​

​

• Structural Crack Injection: Utilized specialized, high-performance structural injection systems to penetrate deep into the concrete core, knitting the columns back together to restore original load-bearing capacities.​

​

• Corrosion & Gas Mitigation: Applied specialized protective concrete finishes to seal the repaired zones against moisture, chemical exposure, and corrosive anaerobic biogases.​

​

• Deep & Shallow Concrete Repairs: Performed localized deep and shallow concrete repairs to remove deteriorated material, restore damaged areas, and reinstate the structural integrity and durability of the affected columns.​

​​

• Industrial Safety Execution: Successfully navigated complex industrial wastewater environments, adhering to strict gas-monitoring and safety protocols during the structural intervention.

Regional Significance & Impact:

The Skyway facility is currently undergoing extensive upgrades to support regional density and growing infrastructure demands across Burlington. Tarpon’s fast-tracked column repairs directly contributed to this mission by:

​

• Protecting Regional Upgrades: Ensuring the core structural components of the existing digester framework are completely stabilized to complement Halton Region's multi-million dollar plant expansions.

​

• Preventing Operational Downtime: By executing targeted structural column remediation rather than massive structural overhauls, Tarpon prevented costly shutdowns of the facility’s biosolid and biogas production.

​

• Environmental Safeguarding: Maintaining the physical integrity of the digesters prevents hazardous environmental leaks, helping the facility continuously meet its strict environmental protection mandates for Lake Ontario.
