No Dig Mole and Grundomat For Sale
Under Road Boring Tool for Trenchless Installation of NBN and Underground Services
Install underground services safely and efficiently without open trench excavation using professional-grade soil displacement pneumatic hammers from No Dig Equipment. Our trenchless under road boring tools are designed for fast installation of NBN conduit, telecommunications, electrical cable, water lines, and gas services beneath roads, driveways, footpaths, and landscaped areas.
Also known as pneumatic piercing tools, impact moles, or Grundomat boring tools, these systems use compressed air to create accurate underground bores while minimising surface disruption, reinstatement costs, and excavation time. No Dig Equipment supplies contractor-grade trenchless boring equipment across Australia with expert support, spare parts, and nationwide delivery.
What Is a Grundomat Soil Displacement Pneumatic Hammer?
A soil displacement hammer is a pneumatic trenchless boring tool that drives through soil using compressed air. Instead of digging trenches, the tool creates a horizontal underground pathway for installing conduit, pipe, or cable beneath existing infrastructure.
These tools are widely used for:
- NBN conduit installation
- Underground electrical services
- Water pipe installation
- Gas line installation
- Telecommunications infrastructure
- Under road boring
- Under driveway boring
- Utility crossing installations
Because the tool displaces soil rather than excavating it, the surrounding surface remains largely untouched, making trenchless installation faster, cleaner, and more cost-effective.
How Pneumatic Piercing Tools Work
Pneumatic piercing tools operate using compressed air supplied from an air compressor. The internal hammer mechanism repeatedly strikes the tool head, driving it forward through the ground while compacting surrounding soil.
This trenchless method allows contractors to:
- Bore beneath roads and driveways
- Avoid major excavation works
- Reduce labour and reinstatement costs
- Minimise disruption to traffic and landscaping
- Install underground utilities quickly and accurately
The process is ideal for contractors working in residential, civil, telecommunications, infrastructure, and utility installation industries.
Benefits of Trenchless Under Road Boring
Faster Installation: Complete underground crossings quickly without large excavation crews or machinery.
Reduced Surface Damage: Protect roads, footpaths, landscaping, and finished surfaces from unnecessary disruption.
Lower Reinstatement Costs: Avoid expensive concrete cutting, asphalt replacement, and site restoration.
Safer Utility Installation: Install conduit and pipe beneath existing infrastructure with minimal environmental impact.
Compact & Portable: Easy-to-use pneumatic boring equipment suitable for confined access and smaller job sites
