FAQs

Question 1

How long should a torch-on roof last in Otago’s climate?

Accepted Answer

With correct substrate preparation and two-layer application, a quality torch-on roof typically lasts 20–25 years in Otago before major maintenance is required.

Question 2

Do I need council consent for internal bathroom waterproofing?

Accepted Answer

Internal wet-area waterproofing usually falls under exempt building work, but the installer must still meet NZBC E3/AS1. Always keep producer statements for future resale.

Question 3

Can I install tiles directly over a liquid membrane on a deck?

Accepted Answer

Yes—tile-over systems are common. Your waterproofer will incorporate a drainage mat and specify flexible adhesives and grouts to handle movement.

Question 4

What’s the best season to waterproof a basement in Central Otago?

Accepted Answer

Spring and early summer offer soil temperatures that support membrane curing and reduce the risk of frost disrupting backfill compaction.

Question 5

Will a waterproofing contractor also fix existing leaks?

Accepted Answer

Most ArchiPro-listed waterproofers provide diagnostic leak testing and remedial work alongside new installations. Include photos when requesting a quote to speed up assessment.
