Some examples are:

- Structural Inspection

- Crack Injection
- Shotcrete removal
- Steelwork repairs and replacement
- Full sandblasting & painting
- High Pressure water blasting (where sandblasting is not applicable)
- Maintenance on services that run under bridges, communication lines, pipelines, etc.
- ActSafe Ascenders - the ability to put our clients, or there representative, up under the bridge to see firsthand the problems or to carry out inspection work.
NZIA has also designed and built many unique purpose built jigs and fittings to make this type of work fast and efficient.
The benefits of using NZIA are that our proven systems & techniques help to minimise:
