Parking Garages

A wide range of concrete repairs and waterproofing solutions could be required at underground parking garages of mid- and high-rise residential or office buildings: concrete crack repair and patching (walls, ceilings, columns, ledge beams), traffic topping and ramp repair, and expansion joint injection.

Our solutions

Negative-Side Joint Injection

Podium roof expansion joint waterproofing does not require above-grade demolition and the existing membrane removal – our industrial-strength materials allow for joint injection to be done from inside the parking garage.

Our solutions

Concrete Restoration

Concrete surfaces can be restored with minimal demolition, since patches as thin as 5 mm can be applied by using our industrial-grade materials – unlike the traditional repair methods that require a two-inch demolition. In most cases, slab replacement can be avoided.

Our solutions

Traffic Topping Repair

Our specialised self-levelling materials allow us to repair traffic topping instead of replacing it, as long as there is sufficient adhesion between the existing surface and the underlying waterproofing membrane. When applied over the top, they seal any cracks and work as a traffic topping.

Application Benefits

Efficient Repair Methods
Since most concrete repairs can be done with minimum demolition, and expansion joints are waterproofed via polyurea injection, the repaired areas can be reopened for public use within 24 hours.
Cost Savings
Thin patch applications, negative-side injection, and no need for forming (thanks to the use of industrial-strength adhesives and polymer cement) contribute to significant savings in terms of time and labour, minimising the overall expense.

Repair methods

To be able to inject a polyurea-based waterproofing material (even from underneath the podium roof), injection ports are drilled on both sides of the joint after it is cleaned out. An industrial-strength adhesive is applied next, and a backer rod (two backer rods for wall joints) is inserted to ensure the injected material will remain in place. A liquid rubber-like material is then injected into the joint, followed by a polyurea foam injection.
