Parkade Restoration with Drainage and Concrete Repairs

This parkade had suffered from poor maintenance and inadequate drainage, leading to water accumulation on the top deck. The standing water caused concrete failures on both the top and underside of the suspended slab, posing structural and safety risks.

Key Solutions Implemented

1. New Drainage Installation:

• New drainage components were installed to eliminate standing water and prevent further damage to the top deck.

2. Concrete Repair on Soffit Side:

• Loose concrete on the underside of the slab was removed.

• Rebar cleaned and treated with a corrosion inhibitor to prevent future deterioration.

• Mapei polymer-modified concrete pumped into forms to complete soffit patch repairs.

3. Topside Concrete Restoration:

• Fast-set Sika grout applied to repair spalls.

• Rapid-cure epoxy used to fill cracks and worn sections.

• Kelmar epoxy membrane coated the top deck to provide waterproofing and long-term surface protection.

4. Finishing Touches:

• Reinstallation of railings and wheel stops.

• Line painting to mark parking spaces and improve functionality.

This comprehensive restoration approach ensures that the parkade is structurally sound and protected from future water damage, extending its lifespan.
