Waterproofing with Polyurea

Applications

Overhead

For use in cantilevered slabs, soffits, and parking garage ceilings, the WALLTITE insulation/air barrier properties provide a high R-value/inch in small spaces compared to traditional alternatives.

Additional benefits of WALLTITE are:

Reduces “cold” floor issues;
Provides ease of application for awkward overhead areas;Will not sag over time;

Strongly adheres and conforms to typical construction substrates (rough and smooth surfaces).

Below Grade Exterior

When used as continuous insulation on the foundation wall, WALLTITE provides these additional benefits: Increases occupancy comfort by reducing interior temperature variations;

Additional benefits of WALLTITE are:

Reduces the potential for condensation on surfaces in the basement;

Provides radon and soil gas protection.

Under Slab

WALLTITE can simplify the addition of an under-slab heating system.

WALLTITE also provides the following benefits:

Helps level the surface;
Delivers high compression strength;
Provides a durable, walkable surface for pouring concrete;

Provides radon and soil gas protection.

Cavity Wall

Besides insulating, WALLTITE also simplifies the process by being an air and vapour barrier.

WALLTITE also offers these additional benefits:

Offers high R-value/inch;
Strongly adheres and conforms to typical construction substrates (rough and smooth surfaces);

No loss in thermal performance due to convective air movement (air going through or around);
Excellent air sealing ability.

Interior/Exterior

The WALLTITE features allow it to be an exterior insulating sheathing and/or interior insulation. As an insulation/air barrier material and/or system, WALLTITE allows for space efficiency due to its high R-value/inch.

Additional benefits of WALLTITE are:

Creates a secondary drainage plane;
Delivers continuous insulation;
Strongly adheres and conforms to typical construction substrates (rough and smooth surfaces);

Excellent air sealing ability;

Ease of application on multi-angled wall construction projects.

Interior

WALLTITE can be applied to the interior of pre-cast and spandrel panel or solid masonry to improve thermal performance. As a continuous insulation layer, WALLTITE provides a thermal break, reducing the potential of condensation.

Additional benefits of WALLTITE are:

Offers high R-value/inch saving valuable floor space;
Strongly adheres and conforms to typical construction substrates (rough and smooth surfaces);

No loss in thermal performance due to convective air movement (air going through or around).

What is Polyurea?

Polyurea is an advanced coating technology that we use for waterproofing purposes. It is a durable and flexible material that forms a seamless protective layer on various surfaces, effectively preventing water from penetrating through.

When applied, polyurea creates a strong bond with the substrate, forming a continuous membrane that is highly resistant to water, chemicals, and physical damage. It is especially beneficial for waterproofing applications because of its exceptional properties.

Polyurea is also known for its long-lasting performance. It is highly durable and can withstand harsh environmental conditions, including temperature fluctuations, UV exposure, and chemical exposure. This means that once the polyurea coating is applied, you can have peace of mind knowing that your surfaces are well-protected against water damage for an extended period. Furthermore, polyurea coatings are versatile and can adhere to various substrates such as concrete, metal, wood, and geotextiles.

Industrial-Grade Waterproofing Systems That Protect What Matters Most

OPC delivers reliable, long-lasting waterproofing solutions for Ontario’s industrial, commercial, and municipal sectors. From below-grade foundations to exposed concrete tanks and tunnels, our waterproofing systems are designed to resist water intrusion, hydrostatic pressure, and environmental wear. We specialize in durable, seamless applications that safeguard your infrastructure against long-term damage—helping you maintain compliance, reduce maintenance costs, and extend the life of your assets.

Polyurea and Advanced Waterproofing Coatings for Demanding Environments

As part of our high-performance waterproofing offering, OPC uses advanced polyurea coatings to create seamless, flexible barriers that bond tightly to concrete and other substrates—even in extreme environments. Ideal for wastewater treatment plants, containment areas, and chemical facilities, polyurea provides rapid-cure protection that resists moisture, corrosion, and impact. Our team will design and apply a custom waterproofing system—including polyurea or other specialized coatings—based on your specific site conditions and performance needs.
