Features of our rock trenchers

Trench-less technology means combing the use of a cable or pipe plough over open ground, under roads,
rails or rivers where open cutting or ploughing would not be possible.

A typical application would be the laying of  33kv trefoil cable plus a copper earth, up to 4 No 40mm ducts for fibre optic control or
telecoms cables plus two 50mm standard yellow marker tapes. These are laid in one pass down to a depth of 2 metres and experience
has shown that there is no requirement for sanding the cables because the fines in the soil are the first layer around the cables.
This results in considerable cost saving and at an average laying rate of 800 – 1000 metres per day the site times and need for long
possessions and fencing off areas  are eliminated. Because no sub soil is brought to the surface re-instatement of the plough run is
completed quickly and the natural seed bed in grasslands or SSSI sites recover quicker.
All our operatives are full time employees of Josef Schnell and are fully conversant with the Health & Safety requirements of
operating within the UK. Together with an environmental policy strictly adhered to we feel that Josef Schnell has the answer to your
utility installation problems, be they electric, gas or water.



UVDB standard

By providing the information requested in the UVDB online questionnaire suppliers will have met the pre-qualification needs of over 50 Utilities. These Utilities use the UVDB to source suppliers and do not need to issue as many of their own questionnaires. There are over 2500 individuals who regularly use the UVDB to create both long and short lists of suppliers and contractors.

Cost Savings 
You know how conventional trenching cuts costs are so hard to improve. Labour costs rise each year and capital equipment rarely
gets less expensive. The added complication of tricky terrain increases the financial headaches.
Our technology and expertise means we can work faster and more efficiently in almost any circumstance. Challenge us to save
you at least 20% on your existing open trenching costs.
How it Works
 The Josef Schnell plough systems use a separate winch unit and plough. The plough is pulled through the ground making a thin
cut whilst laying the cables or pipes in a perfectly-formed tunnel underground.
The ground closes in naturally with reinstatement. In effect, we 'unzip' the ground, lay the cables or pipes and 'zip' it up again.
The result of thousands of hours of practical development, it really is that simple.
It's then possible to lay water pipes of up to 280mm diameter. Where useful, you can lay three water pipes of up to 160mm
diameter simultaneously.
Also possible to lay to depths of up to 2,0 metres. You can lay multiple 11kV cables simultaneously.
Our techniques avoid potential soil contamination during open trenching and significantly reduce times on site.
Make use of environmentally preferable routes which are difficult or impossible with conventional techniques.
We quote Rachel Remnant of The Hampshire and Isle of Wight Wildlife Trust.
"The plough work of the cabling at Bartley Heath was a great methodology in terms of the speedy deployment. It only took a day,
which drastically reduced the amount of time I would have needed to spend supervising the work had it been trenched.
"As a heath land site, which is low in nutrients, the plant life will take some time to recover and carpet back over turned earth.
The plough incision caused minimal disturbance and the plant cover is recovering well. The route followed a main thoroughfare for
walkers (to limit disturbance over the rest of the wildlife area). As a main path for walkers, we wanted to limit the amount of disturbance
caused by the cabling. The mole-ploughing sections are obvious by the reduced soil disturbance, compared to the junction boxes which
involved trenching. The trenching has left areas of boggy mud where the land was previously wet, but vegetated.
limiting damage to the underlying geology and overlying vegetation."

No technique is completely disturbance-free or hazard-free but we're as close as you'll get. Talk to us and find out more.



When installing utilities be they gas `water or electricity we work to a Written Health and Safety policy also a comprehensive Environmental Policy Statement. We offer a fast, versatile, economical and environmentally friendly way to achieve this in any terrain or soil condition from running sand to friable rock . Up to 20 telecom or telemetry cables or ducts, 2 lightning protectors and 2 warning tapes can be laid simultaneously.
The winch truck can be positioned up to 125 metres ahead of the plough and even offset to the side of the route.
