Stormwater Tank Waterproofing: Unleashing the Power of Polyurea Protective Coatings

Proper stormwater management is a cornerstone of urban development, contributing significantly to mitigating flood risks, controlling erosion, and sustaining waterway health. Central to this task are stormwater detention tanks, which are concrete edifices designed to regulate stormwater runoff. However, their effectiveness is often compromised by waterproofing issues.

These challenges have found a robust solution in the form of polyurea protective coatings for water tanks, introduced by IMC/Nukote Canada.

Understanding the Significance of Storm Water Detention Tanks

These engineered structures, also known as retention systems, play a vital role in urban water management by temporarily withholding stormwater runoff. The stormwater, collected from drains during peak rainfall or melting of snow is held back and released gradually, helping to regulate the water flow into nearby sewers, and respective water systems/bodies preventing flooding and erosion.

Addressing the Achilles’ Heel of Concrete Water Tanks

Concrete, while being a durable material for constructing stormwater detention systems, is not impervious to damage. Factors like fluctuating temperatures and ground movements can cause cracks and leaks in the structure, while harsh environmental conditions can wear down the concrete over time. These challenges necessitate a focus on concrete water tank waterproofing to uphold their integrity and durability.

Polyurea Protective Coatings: A Turning Point in Waterproofing Technology

Traditionally, waterproofing has depended on the use of cementitious products, bituminous coatings, or liquid membranes, each with its own limitations and high maintenance needs. Polyurea waterproof protective coatings bring a fresh perspective to this, with high resistance to chemicals and abrasion. This innovative solution creates a sturdy, flexible, and impermeable layer over construction materials, keeping water and pollutants at bay.

Polyurea Protective Coatings: The Frontrunner in Stormwater Detention Tank Waterproofing

The application of polyurea protective coatings brings a slew of benefits, particularly for stormwater detention tank waterproofing:

  • High Resistance: With superior resistance to chemicals and abrasion, polyurea protective coatings are an optimal choice for challenging environments.
  • Seamless Coverage: Polyurea forms a seamless, waterproof membrane, effectively sealing all crevices, thereby preventing leaks.
  • Fast Application and Curing: The application and curing process for polyurea is notably quicker than traditional methods, enabling faster tank return to service.
  • Extended Durability: Polyurea’s resilience extends the life of detention tanks, making it a cost-effective long-term solution.

Polyurea Stormwater Tank Coatings in Action: Case Studies

Case Study 1: TMG Plaza Midtown, Toronto

This project demonstrated the transformative power of polyurea protective coatings in stormwater tank waterproofing. After comprehensive cleaning and preparation, the concrete tank was primed with NUKOTE EP Prime II to ensure optimal adhesion of the coating.

Pipe penetrations were sealed with a polyurethane sealant. The final step involved the application of the Nukote ST polyurea protective and waterproof membrane with a plural component spray system, resulting in a fully waterproof and safeguarded stormwater tank.

Case Study 2: Islington Terrace, Etobicoke

A project at Islington Terrace again showcased the efficacy of polyurea protective coatings, not only for a stormwater tank but also for a cistern tank and a filter room. Each structure was meticulously cleaned and prepped, then primed with a moisture mitigating primer to prepare for the coating.

Flex PU 50 S polyurethane sealant was used to seal pipe penetrations. The Nukote ST M polyurea protective and waterproof membrane was finally applied using a plural component spray system. The project’s successful outcome reiterated the exceptional benefits of polyurea protective coatings for waterproofing.
