GD Harries is a construction company that has grown from a small haulage and plant hire operator in 1977 to become West Wales' cornerstone for quality aggregates and civil engineering solutions. We own seven quarries, four asphalt plants, and eight concrete plants. Our commitment to supporting our local workforce and suppliers drives growth, while our quarry materials and construction services expertise pave the way for a stronger West Wales. We have been working with Carmarthenshire County Council and Nappicycle on a project to surface roads with recycled nappies, tackling two challenges at once: diverting waste away from landfill and the need for sustainable road maintenance. From our quarries to our asphalt and concrete plants, GD Harries is paving the way for excellence across West Wales, proudly supporting local suppliers and our workforce to build a strong local infrastructure.

“The recent Family Fun Day we held at Llys Y Fran Lake was a great success. The weather was typically Welsh for July, but the rain held off, and the sun even came out later in the day to take the chill off the stiff breeze!”
