Solutions for Traffic Topping Repair

While traditional methods would require the existing traffic toping to be removed so that a new layer could be installed, we are able to repair the existing pavement by using polyurea-based membranes. This week we provided this type of solution for the Court House in Toronto, working during the night, not to impact the normal hours of operation. An area of approximately 700 SQF and a cold joint around one of the columns were repaired.

Repair Method

Traffic Topping

The existing deteriorated membrane was removed, and the concrete substrate was ground and cleaned to ensure proper adhesion for the new membrane. Next, all the cracks were repaired with a specialised crack filling material. The membrane application followed: a polyaspartic basecoat was installed, and a large amount of non-slip aggregates was broadcast to provide a safe surface for vehicles and pedestrians. A polyaspartic topcoat was applied next, to fully seal the newly repaired area.

Cold Joint Repair

To repair the bottom of the column, the cold joint (the juncture between the column and the floor) was chipped out first, cleaned, and then coated with a waterproofing material. An industrial-strength adhesive was applied next, followed by a concrete patch. Fiberglass was installed in the end, for durable waterproofing results.
