Expert Answers

Frequently Asked Service Questions Answered

Clear, honest advice regarding project scheduling, approvals, and material warranties.

What waterproofing standard do you use in bathrooms?

We strictly apply AS 3740 (Waterproofing of domestic wet areas) using Class III high-extensibility polyurethane elastomeric membranes across all shower enclosures, subfloors, and perimeter wall upstands, followed by flood testing.

Can we install a freestanding tub in a compact bathroom?

Yes. Our spatial planners reconfigure layouts, utilizing in-wall cisterns, wall-hung vanities, and recessed niches to optimize clearances and accommodate luxury freestanding baths without compromising ergonomics.

How is ventilation addressed to prevent mold?

We install ducted extraction fans venting directly to the building exterior, exceeding NCC Volume Two ventilation volume mandates to prevent condensation buildup and protect timber framing.

Do you provide independent waterproofing compliance certificates?

Yes. Upon completion of membrane curing and testing, an independent licensed waterproofing certificate (Form 15/16) is issued for your property records and council certifiers.
