Concrete Restoration, Waterproofing & Painting

This project involved comprehensive exterior concrete restoration, waterproofing, surface preparation, and painting to restore deteriorated façade areas and improve the building envelope’s long-term durability.

The restoration process included accessing elevated façade areas using suspended scaffolding and rope-access platforms, carefully removing loose, cracked, and delaminated concrete and stucco to expose sound substrate. Deteriorated concrete sections revealed exposed and corroded reinforcement, which were properly prepared before the damaged areas were rebuilt using Sika 123 repair mortar and Spec Mix masonry materials.

Cracked and deteriorated façade sections were repaired through selective demolition, substrate preparation, concrete patching, and reconstruction. Particular attention was given to horizontal bands, structural/concrete elements, corners, parapets, and other areas exhibiting deterioration and water-related damage.

Following the concrete restoration, repaired areas were waterproofed and protected against moisture intrusion. Sika Thorocoat-400 was applied as part of the exterior protective coating system to provide a durable weather-resistant finish and help protect the restored façade from moisture and environmental exposure.

Surface preparation included removal of failing coatings, cleaning, patching, and preparation of the façade to provide a suitable substrate for the new coating system. The façade was then professionally painted, restoring a uniform appearance while providing additional protection against weather exposure and future surface deterioration.
