Concrete Cancer Repairs and Restoration for Windsor Building

Our client approached us to address significant concrete cancer and defective rendering with water ingress on a 2½-storey structure in Windsor.

This project required careful planning and coordination, from managing traffic and installing electrical “tiger tails” to securing council occupancy permits, and even arranging for a knuckle boom to be safely positioned on the street, ensuring every step was carried out smoothly, efficiently and safely.

Before work began, our team conducted a detailed assessment of the building’s condition, identifying all areas affected by concrete cancer and planning the most effective repair methods to preserve both structural integrity and the building’s visual appeal.

Once access and permits were secured, we began by carefully removing all flaking and delaminated paint, along with any loose or drummy render. Areas showing signs of concrete cancer were opened up to reveal the full extent of the damage, and rusted reinforcement was mechanically cleaned before being treated with Nitoprime Zinc to halt further corrosion.

Next, we installed additional dowels where needed and applied an acrylic primer before rebuilding the surfaces with a high-build, 50 MPa cementitious repair mortar. This process included repairing window lintels where the steel reinforcement had been exposed and damaged, restoring both the structural integrity and appearance of the building.

Throughout the project, our team worked meticulously to ensure every repair was executed with precision, taking extra care around delicate areas to preserve the building’s original character and architectural details.
