The capability

Precision at every stage

From installation through routine servicing to end-of-life decommissioning, we work across the full life of a bolted steel tank. Four service lines, set out below.

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.

Build & Install in full

Leak diagnosis, panel and seal replacement, structural repair. Any brand of bolted tank, whoever put it up.

Repair & Refurbishment in full

Liner replacement, internal cleaning and scheduled servicing that keeps a tank watertight and compliant.

Maintenance & Servicing in full

End of life tanks taken down safely. Materials cleared, site left tidy and ready for whatever comes next.

Why Impact

Any bolted steel tank, whoever built it

Impact works on bolted steel tanks the length of New Zealand, for the country’s leading tank suppliers and directly for owners. We are tied to no manufacturer, so a tank is judged on its condition rather than on who supplied it. A good share of our work is remedial, on tanks put up by others, and knowing where an install goes wrong is what makes ours hold.

“Quote from a distributor or a tank owner sits here once Charles supplies a real one.”
