Protecting the membrane before the tiler

A membrane is a coating, not armour.

Owner Inspections · Marsden Park 2765 · 2026-07-20

In short: Waterproofing left unprotected before following trades on a Marsden Park job.

What protection means

Covering the cured membrane so the trades who follow do not walk on, scuff or puncture it.

What we recorded

A Marsden Park wet area where the membrane needed protection before the following trades arrived.

Why it matters

Every pinhole we record started as damage of some kind. Protecting the membrane prevents the defect rather than finding it.

Why it gets skipped

It costs time and materials on a programme where the tiler is already booked.

The connection to pest

A wet area that leaks slowly keeps timber damp, which is the single most common conducive condition on any property.

FAQ

Questions Marsden Park owners ask about this

Is this a defect?

It is a departure from good practice and from the manufacturer's requirements, and the report records it before damage occurs.

Who is responsible?

Your builder, as the party coordinating waterproofer and tiler.

Does it happen often?

Often enough that we look for it specifically once the membrane is down.

What is the link to termites?

Persistent moisture next to timber. A slow wet area leak is one of the ways it starts.
