FAQ
Remedial waterproofing questions
Straight answers for strata managers, committees and builders in Gold Coast.
Can you fix a leak without replacing everything?
Sometimes. We investigate first to find exactly where water is getting in. If a targeted repair will last, we'll tell you. If the system has failed, we'll show you why and scope a proper replacement.
Do you do below-ground waterproofing?
Yes. We waterproof basements, car parks, retaining walls and podiums, using positive or negative side systems depending on access.
How long will the work take?
It depends on the building, access and how far the damage has spread. Your written scope sets out exactly what's involved before any work starts.
Are you licensed and insured?
Yes. Hydro-Tec is licensed and insured for remedial work.
