Every project we undertake is evaluated on an individual basis. Our expert team will make recommendations based on the area, required use and traffic, budget, and other project parameters in order to achieve the best possible result. With that being said, there is a benchmark standard that is accepted in New Zealand and is considered good practice within our industry. For paths and areas that do not experience excessive traffic, a depth of approximately 75 mm is acceptable (allowing an additional 75 mm for any required sub-base). If, however, you are working with a high-traffic area, a driveway, or even a standard slab, then 100 mm is the more accepted depth and will create the structural capacity and integrity you hope to achieve. Speak to your contractor for a more detailed overview of your project.
