what we do

Our Commercial Services

Building Icon

Body Corporate & High-Rise Remedial

Managing strata and multi-storey buildings comes with access and compliance challenges. We carry out rope access leak investigations, balcony membrane rectification and structural remedial works for complex sites.

Injection Icon

Drummy Tile Injection

Loose or hollow tiles don’t always require full replacement. Our controlled injection process re-bonds delaminated tiles from beneath, reducing disruption in commercial and high-end environments.

Building Icon

Insurance, Elevators & Complex Repairs

Complex building issues require clear documentation and methodical repair strategies. We address lift pit waterproofing, failed membranes and structural damage linked to insurance claims and high-value assets.

Our Services

Remedial & Waterproofing Specialists

When you’re responsible for a commercial building or strata property, small issues can quickly turn into costly structural concerns. At QBSA Waterproofing & Tile Injection in Cairns, we provide targeted remedial building services designed for complex situations, not quick cosmetic fixes. Our work includes body corporate and high-rise remedial projects, rope access window leak repairs, balcony membrane failures and concrete cancer treatment. We also carry out non-destructive tile injection for drummy and hollow floors, helping avoid full floor removal where appropriate.


For insurance assessors and commercial property owners, we manage lift pit waterproofing, failed membrane rectification and detailed building repairs with clear documentation and compliance reporting. We regularly work across Far North Queensland, including remote communities, where access and logistics require careful planning and practical experience.


If you’re dealing with ongoing leaks, structural deterioration or an unresolved waterproofing issue, call QBSA Waterproofing & Tile Injection on 0416 006 376 to discuss your project.
