We provide several specialist services and work in collaboration with the client and designers to develop a tailored solution that best meets their requirements.
Our experienced StoneMaster, Drainage Survey and SafetyCam teams work across the country and can quickly mobilise to help deliver safe, cost-effective and sustainable solutions, to the challenges faced on the trunk road network.
Carnell have a long history of working on the Transport Scotland trunk road network.
Since 2005, Carnell have been carrying out roads maintenance work with a main focus on using the innovative solutions we have developed in drainage surveys & remediation, as well as filter drain recycling to benefit Scottish roads.
Looking ahead, we hope to expand on this and look at how our wide ranging capabilities can be used by Transport Scotland in collaboration with Scottish operating companies and local authorities.
Our Operations Manager, Wayne (left) is based in Glasgow and is the lead on developing our capabilities in Scotland.
On joining Carnell, Wayne commented “After 22 years in the industry, including 8 years working for the Scottish operating companies, I’m excited to join Carnell. I’m looking forward to building a team and delivering the safer, greener and more cost-effective maintenance solutions which Carnell have developed to the Scottish market.”

Carnell worked in collaboration with BEAR Scotland, the trunk road operating company for Transport Scotland’s North East unit, to undertake filter drain refurbishment at two locations on the A96 in July 2022.
Using the StoneMaster process to recycle the filter drain media in-situ, provided several carbon, safety and customer benefits over the traditional dig-out and replace method.
The combined 3,750m length of filter drain was brought back to specification in 11 night shifts, 5 fewer than planned.
In June 2023, we completed the M80 J5-6 Filter Drain Recycling scheme for BEAR Scotland.
This followed a SmartScan survey carried out 12 months prior, to identify the drain in the worst condition.
The StoneMaster team completed 2,826m of filter drain refurbishment in just 9 shifts.
BEAR Scotland Asset Manager Laura Gray commented: “Good working with you on this project. It’s an impressive machine.”
Carnell completed a drainage survey on the A96 in Mosstodloch and Fochabers, Moray to the Type 3 specification (plus jetting). Carnell’s specialist teams surveyed 2.2km of road in both the eastbound and westbound verges.
Our in-house Technical Services team QA checked the data before delivering the report. 136 point items and 155 continuous items were identified with asset reports created on their inventory and condition. CCTV surveys were made of the pipework with footage provided along with the drawings and GIS shapefile.
A Ground Probing Radar (GPR) survey was also conducted to identify services, providing information on their type, off-set and depth.
Carnell have undertaken more than a dozen drainage surveys on the South East trunk roads network for BEAR Scotland. These have included schemes on the A1, A702, A720, M8, M9, M80 and M876. Initially carried out to Survey Type 3 standard, we have also provided jetting (pre-cleansing), to suit the client’s requirements.
One example was the M80 to M9 Chattershall merge scheme. We identified 98 point items (gullies and catchpits), and 99 continuous items (pipework and combined filter drain pipe), over a 2.3km length during two night shifts. Detailed survey reports were subsequently provided to the client’s specification to identify structural and service issues and inform decisions on remediation techniques.
Our journey in Scotland started back in 2005/2006 when we carried out several filter drain recycling schemes in the North East for BEAR Scotland and in the South West for Scotland Transerv.
We made a case study at the time, summarised as follows:
“Prioritised sections along the A82 between Stone Arch and Inverbeg on the edge of Loch Lomond were refurbished over a 3 week period, during July and August of 2005.
An estimated 8,200 tonnes of aggregate was recycled during the Project. To dig out and replace this amount of material would have required in excess of 900 HGV movements. Using Carnell’s patented StoneMaster process gave an overall reduction of more than 750 vehicle movements and the associated emissions.”
We co-locate with our sister company QTS at their Rench Farm office near Strathaven, South Lanarkshire (20 miles south of Glasgow).
