The petra Platform

The Petra Ai1 Platform handles the unexpected.

Our Petra Ai1 Platform is a single tool that can address all geologies, at a range of diameters. Because of our flexible design, we're able to provide a vastly simpler, more mobilizable and cheaper service to general contractors and project owners.

Because we can bore through all geologies, our goal is to eliminate change orders. This can only be achieved because of our  our innovation: one machine to rule them all.

Hard rock module

Cutting edge innovation

SPECIAL CALL OUT FOR THE HARD ROCK MODULE

HyBRID POWER SYSTEM

Flexible enough to be powered electrically, with clean diesel or conventional diesel

We started Petra to protect communities from the effects of a changing climate. While it's not always possible to deliver clean energy to the most remote parts of the world, we wanted to design a trenchless system that had the flexibility to be powered by either clean energy or conventional diesel.

- 6/7 modules can be powered electrically
- Petra's hard rock module uses Propel clean diesel, yielding 66% reduction in GHG emissions
- Petra's hard rock module is [insert %] fuel efficient and remotely operated from a control panel hundreds of feet away.

THE MANY Benefits driven by our innovation

Our innovation drives jobsite productivity

Normalized pricing in all geologies

Delivering overall lower projects costs.
No change orders because we can get through all geologies.

Emission-less in the pit

Unlike other conventional systems, there are no emissions in the pit...ever. Period. In fact, the system can be fully emission-less when powered electrically.

15 minutes to swap modules

Interchangeable cutterheads

2mm installation accuracy

Lacus non ultrices diam, placerat eu, tincidunt pulvinar lacus. Felis dui aliquet.

Multiple safety features

Anti-rollover, muck-removal improvements.

Small footprint

The entire system ships in a 40-ft container and its footprint is small enough to be deployed on small streets.

Smaller shaft sizes

Smaller than standard

Flood-proof

Smaller than standard

1 machine, many diameters

Smaller than standard

Workstation for jobsite productivity

Smaller than standard

Up to 10x faster in difficult geologies

Smaller than standard

Up to 90% cheaper than conventional

What is the difference between “trenchless tunneling” and “tunneling”, anyway?

Trenchless technology and tunneling technology are often used interchangeably, but they have very different applications and require different construction technologies. We describe these differences between trenchless and tunneling in this post.
