Negative-side resin injection stops water at the crack or construction joint — without lifting the slab, stripping the membrane or touching finished works above.

The other quote said “excavate”. That is not one line on a variation. It is the slab, the landscaping, the reinstatement and a program you do not get back — on a job you had already mentally closed out.
Water finds the path of least resistance through a crack or construction joint. We fill that path with a resin that expands and cures inside it, then follow with a structural epoxy where the substrate needs it.
You are not buying a bloke with a pump. You are buying an item you can close out and evidence.
What is leaking, why, and what we are treating — in writing, before anyone quotes a number.
Step-by-step methodology, materials and hold points. Attach it to your ITP.
Priced against a defined scope with exclusions stated. Forward it without a caveat email.
Before and after photography, same angle and dated, plus the monitoring result.
If it is wet, structural and awkward to get at, it is the job we want.
Victoria adopted NCC 2025 with no optional transition window. NSW, Queensland and the ACT deferred mandatory adoption to 1 May 2027, so Victorian builders are working to a code the rest of the eastern seaboard has not started.
Part F1 and Part F3 were merged into a single Part F1, Water management, consolidating five performance requirements into two. Part F1 was extended to cover the management of sub-surface water, not only surface water. And the Class 7 and 8 exemption that let basement carparks and storage areas sit outside the waterproofing provisions is gone.
What has not changed is the gap. There is still no Deemed-to-Satisfy pathway for below-ground work — AS 4654.2 covers external above-ground, AS 3740 covers internal wet areas. Neither covers a basement. In practice that means a Performance Solution, usually assessed against BS 8102.
If you want a straight answer on where your below-ground scope sits, ask us. We will tell you even if there is no job in it.
General information only, not a compliance certification. Verify clause references against the NCC online reader and current requirements against the ABCB and the Building and Plumbing Commission.
I spent years on the builder’s side of the defect register — running warranty and customer care for a Tier 1 residential builder. I know what a closed-out item has to look like, and what a leak in a basement is really costing you while it stays open.
Usually yes — active flow is often easier to treat than a damp patch, because it shows us exactly where the path is. Polyurethane resin is designed to react in the presence of water and expand in the crack. Very high flow rates need staging, which we will tell you at assessment.
Not for negative-side injection. It is all done from inside the basement. Some defects — a failed membrane over a large trafficable area, for instance — genuinely do need external work, and we will say so rather than sell you an injection that will not hold.
Most single-joint or single-crack jobs are a day on site, then a cure and monitoring period before we sign it off. We will give you a program with the quote so you can slot it against your dates.
It depends on the run length, the flow and the access. We price a defined scope with exclusions stated so there are no surprises. Assessment and the written diagnosis come before any number.
Yes — inductions, SWMS, permits, out-of-hours and occupied-site access. Send through your requirements with the enquiry and we will have the paperwork ready before we mobilise.
