Why Standard Flashing Fails and How to Fix It— Fixed Once, Not Twice 2025

Even when cavity flashing is installed correctly, water ingress can still occur due to construction details, step-down slabs, or wall junctions that fail to discharge moisture effectively. In this project, we identified water entering office areas beneath joinery, highlighting the need for a detailed investigation and alternative remedial solutions beyond standard NCC specifications.

Blue Background

Wall junction failure • Flashing limits • Moisture tracking

  • Water can enter through upper wall joints, windows, and box gutters
  • Musty smells or flooding often appear after heavy rain
  • Even well-designed cavity systems fail if construction execution is compromised

High-level water entry • Gutter defects • Repeated ingress

  • Even small defects in box gutters can push water into cavity walls, leading to mould, odours, and internal damage. Proper investigation prevents costly repeat repairs.

Slab edge breach • Cavity failure • Remedial membrane

  • Water entering through the slab-to-brick interface is a common issue not solved by patching. This project shows the need for roll-type membranes to redirect moisture safely outward.

Avoid Costly Repairs —

1. Don’t Rely on Quick Fixes
Icon
Icon

Our Preventive Approach:
Simple silicone touch-ups to box gutters or flashing may temporarily stop leaks but won’t fix the underlying moisture source.
Cost Saving

2. Avoid Premature Repairs
Icon

Our Preventive Approach:
Don’t patch walls or replace floors before moisture issues are fully investigated and cured. Doing so often results in repeat repairs.

Cost Saving:
Reduces repair frequency and extends the lifespan of your tiled surface.

3. Get a Professional Assessment First
