Traffic Surface Repair & Waterproofing
Joint Seal is a Toronto-based company trusted by over 300 property managers, specialising in traffic surface repair and waterproofing. Polyurea-based applications offer significant cost savings on membrane and traffic topping repair — including mastic and asphalt surfaces — with no demolition or prolonged closures.

A Complete Solution for Traffic Surfaces
Traditional traffic topping installations require a layer of waterproofing membrane to be installed over a concrete deck, followed by a traffic topping (usually asphalt or mastic), since the membrane is not designed for traffic.
Any traditional repair would require a complete removal and reapplication of the traffic topping and the waterproofing membrane underneath.
Polyurea is designed to serve as both the membrane and the traffic topping, letting us provide a complete solution in a single application. It can be applied over the existing pavement — the most cost-efficient and long-lasting repair available on the market.
Traffic Surfaces Repaired
We can restore underground parking garage floors, exterior parking lots, garage ramps, and more by repairing and waterproofing the existing concrete and asphalt surface, without the need for excessive demolition.
Existing mastic or other types of traffic topping can be repaired without demolition – our waterproofing, decorative, non-slip traffic topping membrane is applied over the top.
A Two-in-One Solution — polyurea-based membranes repair and waterproof any type of traffic coating, and can be applied directly on top.
Why Traffic Surfaces Break
Traffic surfaces undergo normal deterioration due to exposure to heavy traffic, especially in manoeuvring areas, and where exposed to the weather elements.
Repairing them in a timely manner is essential to accident prevention and saving on maintenance costs. Not having to shut down the parking garage for months is a significant benefit of our versatile applications.
Application Benefits
The ability to repair the existing traffic surface, and the use of high-end commercial-grade materials, let us offer cost-effective solutions designed to last over a decade.
Repaired areas can be reopened to traffic within 24–48 hours (72 hours if a polyurethane topcoat is chosen). Large areas, such as extensive parking lots, can be repaired in sections, allowing for continuous traffic flow.
Customisable Decorative Non-Slip Finishes — our urethane, polyurethane, and polyaspartic topcoats offer a wide range of colours, and specialised aggregates create a non-slip, easy-to-clean surface that is safe to drive and walk on.
Our Repair Methods
Traffic Surface Repair
Whether the surface is asphalt, mastic or bare concrete, we repair and waterproof it in place with a polyurea system and a decorative, non-slip topcoat. These are the core methods we use.
Asphalt Repair
Power washing of the surface to be repaired is the first step in ensuring proper product installation. Next, any cracks are repaired and filled, and loose asphalt is removed. High-strength cementitious- or asphalt-based products are used for a fast-setting repair.
An epoxy-based (vapour barrier) primer follows, and aggregates are broadcast next to provide a more lasting bond between the basecoat and the topcoat, as well as a non-slip finish.
A polyurea membrane is then installed and coated with a polyurethane or polyaspartic topcoat broadcast with aluminum oxide.
Mastic Repair
If the existing mastic or any other type of old coating still has good adhesion to the underlying surface, it can be repaired (we use specialised equipment and techniques to test the adhesion).
A specialised primer, chosen based on the type of coating, is applied and broadcast with aggregates for increased bonding. An industrial-strength polyurea membrane is then installed, followed by a polyurethane or polyaspartic topcoat chosen based on client needs.
If polyurethane is chosen, either the aliphatic (UV-protection) or the aromatic (non-UV) type can be applied — the non-UV being less expensive and a good choice for underground garages not exposed to sunlight.
Concrete Repair
If waterproofing is done on a new concrete floor or an extensively recast area, it must be fully set – usually at least 28 days after installation, and with less than 4% moisture. The floor might require profiling (sandblasting, shotblasting, or grinding) to ensure proper adhesion.
Any required surface repairs are done first – crack repair and patching – before the traffic surface is done.
In either case, a polyurea- or urethane-based membrane can be chosen, with a polyurethane or polyaspartic topcoat applied depending on customer needs.
Common questions
Frequently asked questions
Do you have to remove all the traffic topping and redo it?
No. Our applications repair and waterproof the existing surface, depending on condition.
Will our garage or lot shut down for long?
No. Repaired areas reopen within 24–48 hours, and we work in sections to keep traffic flowing.
Must we replace the membrane and the entire topping?
No. Our polyurea applications go on top of the existing surface, repairing and waterproofing it.
Worn ramps, lots or garage floors?
We repair and waterproof asphalt, mastic and concrete traffic surfaces in place with a polyurea system — reopened to traffic in 24–48 hours, with a decorative non-slip finish.
