EQC carried out geotechnical investigations in Technical Category 3 (TC3) in order to understand local soil conditions before the foundations of approximately 10,500 homes can be repaired or replaced.
Drilling was completed on 21 December, 2012. (Read the media release.)

Data management and interpretation
EQC manages the drilling data through the web-based Canterbury Geotechnical Database.
- The data is uploaded to the database when drilling has been completed.
- The data is highly technical. It is available to geotechnical and structural engineers, council officers, and other specialists, to assist them with the design of foundations for obtaining building consent for your home.

Repair of your home
Once the land near your home has been tested, geotechnical and structural engineers will analyse the information and design foundations specific to your property. These designs then go to the local council for building consent.
- If damage to your home has been assessed as under cap ($100,000 plus GST in any one event), this work will be carried out by Fletcher EQR on behalf of EQC.
- If your home is over cap, consenting and repair will be carried out by your private insurer.
Drilling for land data
In some suburbs that have already been drilled as part of the TC3 foundation damage drilling programme, EQC is carrying out further geotechnical investigation to find out more about the soil composition.
This information will be used when settling land claims, and will not delay settlement of building claims.
