We were called to Clydach, Abergavenny, in South Wales by Wizard Eco after their plumbers ran into some trouble while trying to drill core holes through sandstone walls. The team had given it their best shot, but the dense and uneven nature of the sandstone made it a tough task - so they called in our team of CHAS-accredited diamond drilling contractors.
Our job was to complete two 77mm holes and one 125mm hole through solid sandstone to allow for new service installations. This was the perfect example of where experience, the right tools, and specialist knowledge make all the difference.
Sandstone can be extremely challenging to drill through, especially when precision and control are required for service penetrations. Our experienced team arrived on site equipped with our specialist diamond core drilling rigs, ensuring we could achieve clean, accurate results without damaging the surrounding structure.
We set up the equipment to handle the variable density of the stone, using steady pressure and controlled speed to prevent fracturing. With our diamond drilling services, we were able to core the 77mm and 125mm openings cleanly, maintaining a perfect circular finish on both the internal and external faces of the wall.
Our operatives worked efficiently to complete all three holes with minimal disruption to the property, demonstrating why core drilling specialists are the right choice for complex materials like sandstone.

By using precision diamond drilling in South Wales, we delivered a clean and professional outcome for Wizard Eco. The new openings were exactly where they needed to be, ready for the plumbing and ventilation connections to be installed without any rework required.
The client was pleased with the quality of our work and the speed at which we were able to resolve the issue. It was a great example of how our experience and equipment can quickly turn a difficult situation into a straightforward job done right.
