Professional Joint Sealing by Domestic, Commercial & Industrial Waterproofing Specialists
Joints and gaps in buildings—such as expansion joints, facade joints, and construction seams—are some of the most common entry points for water, air, and pests. Without expert joint sealing, these vulnerable areas can lead to leaks, structural deterioration, and costly repairs. Sealtite Waterproofing is Melbourne’s trusted team of domestic, commercial, and industrial waterproofing specialists. With over 10 years of experience and as an Ardex Approved Installer, we deliver reliable, long-lasting joint sealing solutions for homes, businesses, and industrial properties across all Melbourne suburbs.

Water leaks and internal damage
Loss of energy efficiency due to air infiltration
Structural movement and cracking
Mould, mildew, and health hazards
Pest intrusion and material degradation
