“Following the completion of the soil treatment works to the car park area at our Airdrie site, I would like to pass on our thanks to everyone involved with the project.  The proactivity of the GDL team coupled with the organisation of the works made the project a great success.”

“The soakaway job was completed in one day and the quality of the work was excellent. If we need to use a company to drill bore holes in the future, it will be GDL.”

“The contracted works went very smoothly.  The guys at GDL are extremely knowledgeable in their field and very easy to deal with.”

Andrew Taylor, Commercial Manager, Barratt North Scotland


“Further to the completion of the Kerse Road Bridge CFA Piling works Stirling Scotland, I would just like to say that the team was the most hardworking, calm and proactive group I’ve had the pleasure of working with. Even at times when most others would have packed their bags these guys kept going. The job itself was challenging with a rig either side of the railway providing two separate projects within one! Which didn’t phase the senior GDL staff present and overcome with great success.”

Stuart Grant, Operations – Rail & Electrification, Morgan Sindall


“Following a professional tender, GDL were appointed to deliver our CFA contiguous piled wall and foundation solution for our new residential development at Great Junction Street, Edinburgh.  The site was extremely challenging and despite working in a very confined area, the experienced team from GDL delivered their works in a very concise and organised manner. Communication between GDL and our groundworks contractor was excellent which was critical given the nature of the site and we look forward to working with them again soon.”
