01
Foundation
Nothing about a tank forgives a bad base. The ring beam or slab has to be flat and true before the first panel goes anywhere near it, and a few millimetres out here is a leak later.
Capability 01
Build & Install
New tanks assembled on site. A single farm tank, or a multi-tank project with steelwork and civil works, our crews are doing this every week of the year.
What goes up
The scope of an install
Bolted steel is its own trade. It is not welded tank work with different bolts, and a crew who treat it that way leave you with a tank that weeps.
- 01
Any brand of bolted tank
We put tanks up whoever supplied them. Bolted steel only, no welding on site, which is the whole reason bolted construction exists.
- 02
One tank, or a yard full
A single farm tank is a job. So is a multi-tank project with steelwork and civil works alongside it. The crews are doing both every week of the year.
- 03
Roofs and roof steel
Rafters, roof sheets and aluminium geodesic domes, set with the crane and fixed off.
- 04
Liners
Floor and wall liners fitted and sealed, for tanks that need one from the day they go up.
- 05
Access and fit-out
Ladders, caged access, platforms and handrail, so the tank can be reached and inspected once we are gone.
- 06
Nationwide
Christchurch based with crews working both islands. Distance is a logistics problem, not a reason to say no.
On site
How a build runs
Four stages, in this order, every time. The order is not negotiable and neither is getting the first one right.
02
Shell
Panels bolted up course by course with the seals seated as it goes. This is the stage that decides whether a tank holds, and it is the stage we get called back to fix on other people's work.
03
Roof
Rafters and sheets, or an aluminium dome, lifted in and fixed off. Most of this work happens on the crane, which makes it the part of a build that rewards a crew who have done it before.
04
Liner and fit-out
Liner in and sealed, access steel on, and the site cleared. The tank gets handed over clean, which sounds like a small thing until you have been handed one that wasn't.
Pending from Charles: how far the scope reaches into civil works and pipework, and whether Impact offers design and supply or install only.Pending from Charles: confirm this sequence matches how the crews actually work, and which stages Impact carries out itself.
Where they go
Five sectors, one set of hands
What changes between a fire water tank and an effluent tank is the liner, the fittings and the compliance around it. The steel gets the same treatment either way.

- WastewaterEffluent and treatment
- IndustrialProcess water and product

The other three
One crew for the whole life of the tank
Most owners meet us at one of these four and find out about the rest later. You do not need us to have built a tank to get us to look at it.
02
Repair & Refurbishment
Leak diagnosis, panel and seal replacement, structural repair. Any brand of bolted tank, whoever put it up.
Read more 03Maintenance & Servicing
Liner replacement, internal cleaning and scheduled servicing that keeps a tank watertight and compliant.
Read more 04Deconstruction
End of life tanks taken down safely. Materials cleared, site left tidy and ready for whatever comes next.
