TRAFFIC SURFACE REPAIR & WATERPROOFING

Joint Seal is a Toronto-based company trusted by over 300 property managers.

Our division specializes in traffic surface repair and waterproofing.
Polyurea-based applications offer significant cost savings in membrane and traffic topping repair, including mastic and asphalt surfaces.

No demolition or prolonged area closures are necessary.

OUR SERVICES

 

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, which allows us to provide a complete solution in a single application. It can be applied over the existing pavement, without having to remove the old traffic topping and the membrane underneath. This application is the most cost-efficient and long-lasting repair currently available on the market.

Traffic Surfaces Repaired

Asphalt Repair

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.

Mastic Repair

Existing mastic or other types of traffic toppings can be repaired without demolition – our waterproofing, decorative, non-slip traffic topping membrane can be applied over the top.

 

Concrete Repair

We are specialised in concrete surface repair – we are able to do extensive crack repair and patching, restoring the surface as needed, ahead of the waterproofing application, providing lasting results and preventing issues in the future.

A Two-in-One Solution

Polyurea-based membranes repair and waterproof any type of traffic coating - they can be applied directly on top.

 

APPLICATION BENEFITS

Why Traffic Surfaces Break

Traffic surfaces undergo normal deterioration due to exposure to heavy traffic, especially in maneuvering areas, and where exposed to the weather elements.

Repairing them in a timely manner is essential in 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.

Our Solutions

Polyurea-Based Systems

Polyurea waterproofing membranes offer a much more durable solution for a variety of surfaces. Different types of non-slip,
easy-to-clean finishes are available, depending on the client needs, budget and site requirements.

 

Urethane-Based Systems

Using urethane-based waterproofing membranes offers a less expensive but also a less durable solution. A non-UV urethane is used as a basecoat, followed by either a non-UV or a UV-protection topcoat, depending on whether there is exposure to sunlight.

Application Benefits

Cost-Efficient

The ability to repair existing traffic surface and the use of
high-end commercial-grade materials allow us to offer cost effective solutions designed to last over a decade.

 

Low Downtime

The repaired areas can be reopened to traffic within 24-48 hours
(72 hours if polyurethane topcoat is chosen by client), which minimises closure times. Large areas, such as extensive parking lots, can be repaired in sections, which allows for continuous traffic flow.

Customisable Decorative Non-Slip Surface Finishes

Our versatile urethane, polyurethane, and polyaspartic topcoats offer a wide range of colours designed to create a bright, decorative surface finish.
The use of specialised aggregates generates a non-slip, easy-to-clean surface which is safe to drive and walk on.

Adaptable Waterproofing Systems

Both polyurea- and urethane-based systems provide a great value serving our customers' needs.

 

REPAIR METHODS

 

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 a 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, broadcast with aggregates for increased bonding. An industrial-strength polyurea membrane is then installed, followed by a topcoat chosen based on client needs – either polyurethane or polyaspartic.
 

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 parking garages where the floors are 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 concrete 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 a urethane-based membrane can be chosen. If a polyurea-based waterproofing basecoat is installed,
a polyurethane or a polyaspartic topcoat follows. If an aromatic 
(non-UV) urethane basecoat is chosen, then an aromatic or aliphatic (UV-protection) topcoat is applied, depending on customer needs.

Cost & Time Savings

The most cost-efficicent system available - no extensive demolition or closure times needed.

FAQs

Extensive Demolition not Needed

Q: Is it necessary to remove all the traffic topping and completely redo it?
A: No, our applications are designed to repair and waterproof the existing traffic surface, depending on its condition.

Low Downtime

Q: Will our parking garage and parking lot have to be shut down for a long time during repairs?
A: No, the repaired area can be reopened to traffic within 24-48 hours, and we do the repairs in sections, allowing for continuous flow of traffic.

A Single Application

Q: Do we have to replace the waterproofing membrane and the entire traffic topping?
A: No, our polyurea applications can be applied on top of the existing traffic surface, fully repairing and waterproofing it.
