Welcome to Testdrill NZ Limited          

We at Testdrill have a fast and efficient cost effective method of testing the stability of the earth for foundations and other structural designs. 
If you're considering buying a section then our services could be just what you need for peace of mind before making that offer.
If you've already bought and are looking to build then chances are you will need a Penetrometer Test done before you can firm up any foundation design or make any structural changes.
Some councils have made site testing mandatory before construction and we believe it is only a matter of time before it is a nation wide requirement.
