NWT Consultants, located in Yellowknife, Northwest Territories, is a small but growing business that analyzes a variety of construction materials before they are used by contractors. The testing procedures are specific to the individual materials used because reagents used for testing react differently based on their composition and the quantity used. How they are introduced into the materials for testing is also important. During the month of December 2021, NWT completed 36 different jobs.
