For investors

Cutting rock and concrete where access is difficult.

Rockslice is developing a compact system that cuts rock and concrete from one side. Several prototypes have cut stone and concrete. We are now integrating the complete system for field tests.

The problem

Small removals. Large operations.

Tunnels, power stations and other structures that must stay in use need openings, repairs and space for new equipment. The section to remove is small. The work around it rarely is.

  1. Access

    The material sits behind a wall, under equipment or deep in a structure. Reaching it is often the hardest part.

  2. What stays

    Cables, machines and the structure around the cut must stay in use and undamaged.

  3. The whole job

    Mounting, water and slurry, lifting the material out and cleanup decide the real cost and schedule.

The invention

The cut happens at the end of the arm.

The blade cuts the material. The water drives the blade.

Evidence and next milestone

Tested in the workshop. Field tests are next.

  1. Tested

    Prototypes have cut stone and concrete

    Several prototypes built and tested on rock blocks and concrete.

  2. In progress

    System integration

    Pump, rail, carriage, arm and head are being put together as one system.

  3. Ahead

    First field test

    A first accessible job, chosen to learn about operation and equipment.

  4. See testing and development

Where it starts

Tunnels and hydropower.

Owners there need openings, equipment space and repairs in structures that stay in service. A first concrete task at a hydropower site is planned. Utility work and concrete rehabilitation are related applications to assess later.

The business

Equipment and replacement blades.

Ambition

The intended model: useful jobs lead to repeat use, active equipment and demand for new blades. Training and support come with the equipment.

  1. Step 1

    A useful job

    A tunnel or hydropower job where the whole operation becomes simpler.

    Depends onCustomer value over the whole job

  2. Step 2

    Repeat use

    The same owner or contractor chooses it again for similar work.

  3. Step 3

    A method teams can repeat

    Setup, cutting, water handling, lifting and cleanup described, with training and support.

  4. Step 4

    More crews, more rigs

    More teams, then related applications once each has been tested.

    Depends onHow often a rig is actually used

  5. Step 5

    Replacement blades

    Every rig in use wears out blades. Blade demand follows active equipment.

    Depends onBlade wear and blade life

Each step depends on the one before. Field tests must first show customer value, blade life and how often the equipment is used.

The larger ambition

Our ambition is to set a new standard for how the world cuts rock and concrete.

Keep what stands
Remove only the section that has to go.
Reuse concrete
Cut pieces that could be used again. A reuse task is planned.
Rock for concrete
Cut rock replacing some new concrete. So far only a modelled idea.

Ambition Preservation and reuse are ambitions. Any environmental benefit still has to be measured.
