Why it matters here

Waterproofing inspections on Riverstone builds

Wet area rectification is the most expensive defect category in a new home, because correcting it after tiling means taking the room apart. Our Riverstone jobs picked up sealing and caulking still required to floors and walls at handover, along with a shower screen needing sealing, both of which are downstream of decisions made when the membrane went down. Every photograph on this page was taken at practical completion, not at this stage. They are here because each one is an item that belongs earlier in the build and survived to handover, which is the clearest argument we can make for inspecting when the work is still open.

What we find at this stage in Riverstone

  • Coverage short at walls and terminations
  • Junctions and penetrations not sealed
  • Falls not carrying water to the waste
  • Membrane damaged before tiling
  • Sealing and caulking left incomplete to floors and walls

FAQ

Waterproofing inspections in Riverstone: common questions

Which standard applies?

AS 3740 for domestic wet areas, alongside the National Construction Code and the ABCB Housing Provisions.

Do you flood test?

No. That test cuts into finished work and belongs to the waterproofer's own process.

How long is the window?

Often two or three days between the membrane curing and the tiler arriving.

What does failure look like later?

A damp skirting or a stain on the wall of the adjoining room, a year or two after moving in.

What if tiling has begun?

We assess what remains exposed and record the areas already covered.

Who fixes it?

The builder, coordinating waterproofer and tiler, and the report gives them the location and the clause.
