Our sealing crews are perfectly placed to assist on projects of any size. We carry out high quality work for residential and commercial clients across the South Island.

No job is too big or small; and our skilled teams of engineers, project managers, foremen and crew all take pride in working right throughout our region. Even outside Canterbury, there aren’t many parts of the South Island we haven’t sealed.

We employ the latest technologies in both bitumen and emulsion binders, and can recommend the benefits and risks of each product, tailored to your specific project. Using chip sourced from our own quarry means we can test it onsite at our laboratory and fast turn around in supply is never an issue. Isaac use a fleet of modern sprayers with built in data analytics ensuring a high quality of service with accurate reporting on litres used and area sprayed.

Our sealing teams work across the full spectrum of project size from small patch repairs on residential driveways, to multilane highways across the South Island.
