Client Background
A property manager in Coorparoo reached out after tenants reported a persistent leak appearing through the ceiling below the main bathroom. The apartment was part of a 1980s brick complex with several similar waterproofing issues throughout the building. The owner needed a cost-effective repair that would prevent further water ingress — without the downtime and expense of full bathroom renovation.
The Problem
Upon inspection, our team identified multiple points of failure inside the shower:
- Cracked wall grout and open joints along the floor perimeter
- Peeling silicone at the base of the shower screen
- Mould build-up under existing sealant
- Water tracking beneath tiles, escaping into the slab and ceiling below
These issues were typical of older Coorparoo apartments where the original waterproofing membrane had broken down over time, allowing slow moisture leaks to spread unnoticed.
Our Solution
Platinum Seal recommended a full epoxy shower re-seal system — designed to fully waterproof the shower surface without removing tiles.
Process:
- Grout Removal: All old and damaged grout was mechanically removed from wall and floor joints.
- Sanitisation: The shower was deep-cleaned and treated with anti-mould solutions.
- Epoxy Application: Premium Mapei epoxy grout was applied to all joints to create a fully sealed, long-lasting finish.
- Final Sealing: Fresh colour-matched silicone was installed around all perimeters and fixtures for flexibility and protection.
The entire Coorparoo leaking shower repair was completed in one visit, allowing the property manager to resolve the maintenance report within 24 hours.
The Results
✅ Leak fully sealed — no more water penetration into the ceiling below
✅ No tiles removed or replaced — saving the owner thousands in renovation costs
✅ Fresh, mould-free finish that restored the shower’s appearance
✅ Tenants able to use the shower the next day with zero disruption
