Earthworks in Northland
Northland’s clay and sloping land make drainage, retaining and accurate levels important on almost every site. Getting earthworks right at the start saves problems once building begins.
Tips for earthworks
- Find services first – locate cables and pipes before digging.
- Check consent – larger earthworks may need council consent.
- Plan stormwater – decide where water will go before shaping the site.
