Waterproofing and below-ground services for commercial buildings

Waterproofing Contractors in Calgary, Edmonton and Vancouver

In Calgary, Edmonton and Vancouver, we need to take waterproofing seriously.

The team at United Roofing Inc. is dedicated to waterproofing for commercial building projects.

Our team of professionals is tasked with ensuring that every project we work on considers effective water protection for every commercial building.

This usually involves two distinct approaches:

  • Below-ground (below-grade) waterproofing services
  • Coating systems that protect above-ground structures from water

In providing these services we will work closely with general contractors, architects, engineers, inspectors and building owners to design, install, and maintain the right solution that fits your budget.

What waterproofing services do we provide?

With our extreme weather conditions in Alberta, water can play havoc with the structural integrity of buildings unless they are adequately protected.

A combination of storms and extreme temperature variations means that if water can find a way into your building, it will.

United Roofing Inc. specializes in keeping the water out.

This means applying the right waterproofing technologies to the right parts of the building.

We will assess what’s required and then use everything from cold-applied materials to hot pour rubberized asphalt and polyethylene membranes to deliver a first-class waterproofing solution.

This includes the following commercial waterproofing services in both Calgary, Edmonton and Vancouver:

Blind side wall waterproofing in Calgary and Edmonton

Blind side wall waterproofing

This is where a below-grade waterproofing membrane is attached to the soil-facing part of the construction.

It is applied before the concrete foundation is cast against it and is a suitable solution when the exterior faces of foundation walls will become inaccessible.

Parkade slab waterproofing in Calgary and Edmonton

Parkade slab waterproofing

For commercial properties with a multistory parking garage, it is essential to waterproof the parkade slab for structural integrity.

We can provide a range of waterproofing solutions specifically suited to this purpose and an installation team experienced in getting the job done.

Foundation wall waterproofing in Calgary and Edmonton

Foundation wall waterproofing

Problems with water leaking through the foundations are every building owner’s nightmare.

Protecting the outside of foundation walls with a waterproof membrane is often the best solution to prevent water infiltration. We will discuss your requirements with your team and ensure that the right protection is installed.

Tunnel waterproofing in Calgary and Edmonton

Pedestrian traffic coating in Calgary and Edmonton

Pedestrian traffic coating

Pedestrian traffic coating protects concrete surfaces that receive a high amount of pedestrian traffic.

These are susceptible to wear and tear as well as weathering from the sun and other elements. This can allow water to seep in and damage the surfaces. By protecting these areas with appropriate waterproof sealants, you extend the life of these zones.

Concrete restoration

Horizontal concrete structures can be cleaned, repaired, and overlaid with a new surface to extend their lives.

During this process, new waterproofing protection such as joint sealants, traffic bearing coatings, and concrete sealers can be added to prevent further problems with water damage.

Mechanical room coating

Mechanical rooms must be kept free of water to prevent slips, falls, and damage to machinery.

We can help prevent water seepage through cracks and joints with the use of specially textured and adhesive coatings that protect these areas from damage.
