We were brought in by Wynnes Construction to carry out specialist concrete cutting and removal works at Wrexham University. The task was to remove an existing concrete wall section where a window opening was being converted into a new doorway.
This new doorway would bridge together two separate buildings, so accuracy and structural control were essential. The wall measured approximately 2 metres wide, 850mm high, and 200mm thick, and the work needed to be completed cleanly to allow the next phase of construction to progress without delay.
To manage the removal safely and precisely, we used a combination of stitch drilling and controlled concrete sawing. The lower section of the wall was stitch drilled, allowing us to weaken the concrete in a controlled manner and prepare it for clean removal.
Once the stitch drilling was complete, we moved on to vertical cutting using our Husqvarna Pre-Cut system and Husqvarna ring saw. This approach allowed us to section the wall into manageable pieces, ensuring each cut remained accurate and reducing stress on the surrounding structure.
By combining these techniques, we were able to maintain full control throughout the removal process while working efficiently within the existing building layout.
Working within an active university setting meant that cleanliness, noise management, and safety were all key considerations. Our team worked methodically, keeping dust and debris under control and ensuring the area remained safe for other contractors on site.
The decision to cut the wall into smaller sections helped minimise disruption and allowed the concrete to be removed smoothly without unnecessary force or vibration.
Once the wall section was removed, the new doorway opening was left clean, square, and ready for follow-on works. Wynnes Construction were able to move straight on with forming the connection between the two buildings, confident that the opening had been prepared to the correct dimensions.
This project is a strong example of how stitch drilling and controlled sawing techniques can be used together to safely adapt existing structures without compromising surrounding elements.
