Four Disciplines
One Trusted Delivery Partner
High Group brings together demolition, excavation, earthworks and haulage under one experienced team. By self-performing every stage of the groundworks process, we provide builders and developers with greater control, better coordination and reliable project delivery from start to finish.

- Selective demolition & strip-outs
- Heritage & sensitive demolition
- Licensed asbestos removal
- Concrete cutting & removal
- Site clearance & waste management
