Our Balcony Waterproofing Process
Inspection & Assessment
Our team begins with a detailed inspection of your balcony to identify any existing leaks, cracks, or structural concerns. We also check drainage and tile conditions to determine the best approach for waterproofing balcony floor or deck.
Surface Preparation
Our balcony waterproofing specialists prepare the surface by cleaning, grinding, and repairing cracks to create a smooth, stable base. Proper preparation is essential for the waterproofing membrane to bond effectively and deliver long-lasting protection.
Waterproof Membrane Application
Our balcony waterproofing professionals apply high-quality liquid or membranes designed for the Gold Coast & Brisbane climate. These flexible, durable membranes create a watertight seal that expands and contracts with your balcony’s movement.
Detailing & Sealing
Special attention is given to joints, edges, and penetrations (such as drains and balustrades), as these are common leak points. We seal and reinforce these areas to provide complete protection.
Final Coating & Finishing
Once the membrane has cured, our licensed balcony waterproofing applicator near you apply protective coatings or re-tile the surface (if required). This final step ensures your balcony looks great while staying resistant to water damage.
Quality Check & Guarantee
Before we finish, we carry out a full inspection to confirm that everything is sealed and watertight. All our balcony sealing services are backed by a workmanship warranty for your peace of mind.
