The gravel material used in our ground improvement technique is a very specific and unique grading made specific from local material for Christchurch conditions, i.e. specific grading and broken face content.

Why TC3 Soil Improvement Matters: Costs & Benefits

For each client we begin by assessing the technical feasibilities of what can be achieved in terms of ground improvement on your land. We balance a scientific assessment of possibilities with economic considerations to develop the best custom solution that will deliver you the highest grade of land possible for a cost that makes sense.

By upgrading the soil quality of your TC3 land, you open up new building options that improve safety and reduce costs. These options are often less expensive than TC3 foundations (or comparable in price). By building on stone columns you end up with a comparable or lower cost for a much safer, more stable foundation and negated risk of liquefaction on your property.

How Our Ground Improvement Services Work

NZ Ground Improvement handles the entire ground improvement process for you from start to finish. Our independent expert designers create a tailored solution for your property, with soil improvement goals and key metrics laid out in detail. We use dedicated precision rig technology, unmatched by any other company in New Zealand, to inject a unique grade of locally-sourced stone which is compacted to form columns, densifying and strengthening the surrounding soil.

The process typically takes between three days and several weeks depending on the size of the site and initial condition of the soil. We track progress via our sophisticated GPS technology and test rigorously to ensure the work matches specifications down to the millimeter. The end result is an upgraded, stable, safe piece of land ready for your builders to move in and commence work on.

More effective than other ground improvement alternatives, stone piling provides superior protection against the risks of future earthquake-induced liquefaction in Christchurch.
