Utility Room Waterproofing

Joint Seal Waterproofing is a Toronto-based company, specializing in utility room waterproofing. Our services cover a vast geographical area, from Hamilton to the City of Toronto, and the surrounding GTA communities.

Our Utility Room Waterproofing Services

Such rooms normally present a special challenge in terms of maintenance: water and oil leak from the machinery, right onto the concrete, and there are mechanical intrusions from heavy equipment being moved across the surface, leading to its damage and deterioration. We provide a long-lasting solution that ensures great-looking floors thanks to the use of specialized materials.

A Complete Restoration Made a Reality

No matter the extent of the damage, utility room floor surfaces get a second chance.

Repair Methods

Floor Restoration

Getting the flooring completely restored is a matter of three steps:

  1. The floor is shaved to remove paint and any other contaminants and oils. Having clean and exposed concrete is a must in order to ensure proper installation.
  2. Primer is applied. A specialized, industrial-strength waterproofing primer anchors itself to concrete so well, that even if the new paint on top of it get scratched, the concrete will remain protected.
  3. The surface is painted while the primer is still curing: this creates adhesion between paint and concrete, so the paint cannot delaminate. This layer of paint serves both as a decorative coating and a second protective layer.


All loose unsound concrete is removed, and concrete surfaces are cleaned in preparation for patching and restoration.

Under traditional repair methods, patching concrete requires a minimum of two-inch demolition in the affected area. The use of industrial-strength specialized adhesive and polymer cement permits thin-patch applications, even on walls and ceilings. The combination of these materials creates a monolithic patch which is able to restore structural integrity of repaired slab.

Crack Repair

To repair a crack on any concrete surface, a clearly defined procedure is followed. Cracks are prepped and then filled with specialized, industrial-strength adhesive, after which they are filled with polymer cement and a waterproofing primer.

In Our Clients’ Words

Satisfied Customers at TCC1151

We hired Joint Seal to waterproof our utility room, as well as do some crack repair and patching.  The floor surface receives a lot of damage from water and oil leaking from the machinery, so keeping such rooms maintained is quite challenging. In the past, we’d had some disappointing experiences with repairs in this area – the floor got damaged again very quickly.

Even though we had to wait for Joint Seal to come and do the work, it was worth it in the end. Their in-house crews really know their stuff: they thoroughly cleaned the surface before applying specialized materials that do stand the test of time. They also applied a final layer of paint that not only protects the surface even further but even looks good!

We had Joint Seal do other waterproofing jobs on our premises in the past, and we were pleased to see the same crew members who always do high-quality work. That’s one of the things we love about this company – we know exactly what to expect. We will be calling them again if other areas of our building require concrete repairs or waterproofing.
