About Us
Established in 2020, Subterra has been involved in geotechnical engineering consulting across New Zealand ever since. We provide geotechnical engineering services in Christchurch and the greater Canterbury area, as well as frequently servicing the West Coast and Nelson areas.
The key elements of Subterra’s success have been:
Quick Delivery
Competitive Pricing
Good Communication
Subterra is a fully work-from-home business, which means minimal overheads. This approach keeps costs low without compromising on quality.
Following Cyclone Gabrielle in 2023, Subterra assessed many properties on behalf of the Earthquake Commission as part of their EQC land damage claims.
Deep Machine Testing
In some cases, such as where a site is susceptible to liquefaction damage in a seismic event, deep machine testing and analysis will be required, in addition to shallow hand investigation.
Common methods of deep machine testing include Cone Penetration Tests (CPT’s), Dynamic Probe Super Heavy (DPSH), and machine boreholes with core sampling and Standard Penetration Tests (SPT’s).
Geotechnical Reports
Geotech reports can be used for many purposes, such as to support a Resource Consent or Building Consent application, or during the due diligence phase of property sale to inform potential purchasers of the geotechnical constraints of a site.
A geotechnical report will include a combination of site observations, desktop study, and quantitative analysis, depending on the scope of the project.
Design
Following the initial investigation and desktop study phases of a project, Subterra will provide design parameters for foundations and any hazard mitigation measures which might be required.
