From site prep to lush landscaping – weve got you covered

Wellingtons landscape can be as challenging as it is beautiful. With steep hills, rocky terrain, and unpredictable weather, earthworks are often essential to get your project off the ground. At BK Patterson Earthworks, weve got the machinery, experience, and expertise to tackle all your earthworks needs – in-house, and without the delays that can come from relying on subcontractors. From clearing and levelling to full foundation prep, we take care of everything.

Our earthworks services:

Site clearing & excavation

Before any new builds or extensions take place, the site has to be prepped. We handle site clearing, rock & concrete breaking, general demolition, and removal of unwanted materials; as well as excavation and drilling to prepare the land for construction. Whether it’s a tricky hillside or a compact urban section, we’ve got the machinery and skills to manage it efficiently.

Drainage solutions


Good drainage is key in Wellington, where the rain can be relentless. Poor drainage can lead to water pooling, erosion, and damage to your foundation. We take a smart, long-term approach to drainage, ensuring your site is well-equipped to handle the elements for years to come.

Retaining Walls & Foundation Work


Wellington’s famous slopes can make building challenging, but with solid foundation work and retaining walls, you can make the most of any section. We’ll assess your site, provide the right retaining solution, and ensure that your foundations are rock solid – literally.

Driveways & Accessways

Wellington is renowned for it’s difficult home access. From driveways to pathways, we make sure access to your home is level, safe and secure. We offer earthworks solutions that balance practicality and aesthetics, ensuring that your property access not only looks great but is also functional.
