Abstract
New Zealand is a pioneer in the field of earthen constructions and has developed a number of regulations to serve architects, structural engineers and beneficiaries. The regulations adress material resistance, thermotechnical characteristics, on-site testing methods, building techniques, etc. Through the information contained, a framework is created to meet the needs of construction materials with low environmental impact. This article proposes a review of some soil testing methods found in the international literature for its use as a construction material.
