5 Ways Waterproofing Can Delay Your Project (And How to Avoid It)

On tight construction schedules, waterproofing often feels like a small trade, until it causes big delays. Here are five reasons waterproofing can hold up Sydney building projects, and how to prevent it.

1. Poor Surface Preparation

Unclean or uneven substrates cause bonding issues, leading to rework. Always allow proper curing and priming time.

2. Incorrect Membrane Selection

Each area, basement, podium, or wet room, requires a specific system. The wrong product may not meet compliance or environmental conditions.

3. Weather Delays

Sydney’s humidity and rain affect drying times. Use fast-cure membranes and plan sequencing accordingly.

4. Lack of Testing

Skipping membrane thickness or flood testing leads to costly re-tiling later. We perform PosiTector 200 testing on every layer to ensure compliance before handover.

5. Coordination Breakdowns

Late scheduling with tilers, concreters, or painters can stall progress. Involving waterproofers early keeps the project moving.

With clear communication, testing, and experienced contractors, waterproofing becomes a smooth step, not a setback.
