Other Specialist Services For the Utility Sector
- Joint sealing is a vital process for ensuring the longevity of concrete and asphalt surfaces. It involves the application of sealant material to expansion or contraction joints, which allows the concrete or asphalt to move through natural expansion and contraction heat cycles while maintaining a seal, preventing water and contaminate ingress into the joint
- Diamond Wire Sawing is a powerful and flexible technique that uses linear wire embedded with diamond beads to cut through reinforced concrete, masonry, and other hard materials. It is a fast, quiet, and effective way to cut large structures and plinths with precision, and it is especially useful on projects where deconstruction work requires careful consideration.
- Hydraulic Bursting is also known as hydraulic splitting, or hydraulic/silent demolition. Bursting is a method used to burst large volumes of concrete in a controlled methodical manner.
- Floor & Wall Chasing utilises diamond sawing equipment to create accurate and precise chases in your floors and walls for ducting, cabling or pipes keeping them safe, tidy & hidden below the surface.

Vac-Ex Excavation
How we utilise Vac-Ex machines in Construction
Vac-Ex is a non-intrusive method of excavation that uses compressed air to loosen up the ground, followed by suction to remove the loose material. A Vac-Ex machine can generate a powerful stream of air with an operator controlling the intake nozzle, providing full control of the excavation while they remain at a safe distance. This method significantly reduces spoil and dust because all of the extracted material is sucked directly into sealed collection chambers on the machine, making it particularly suitable for use in confined spaces.
Diamond Drilling
Whether you need to form openings for redesign or refurbishment, or to isolate areas prior to demolition, we’ll work with you to achieve your goals accurately, safely, and at a competitive price.
Diamond drilling is a specialised drilling technique used to cut through the hardest reinforced concrete with utmost precision. The process involves using diamond-tipped drill bits, connected to either an electric or hydraulic drill motor and rig, allowing careful control over the location and speed of hole formation. Diamond drilling allows our team to make holes of varying diameters and shapes when linked together in a stitch-drilled pattern, and is a quiet and non-percussive technique.
Castle & Pryor uses only experienced and fully qualified engineers who have undergone extensive training to NVQ Level 2 in the use of diamond drilling tools. We’ll utilise a range of equipment, with electric and diesel-powered drills available in multiple sizes to suit the needs of every client.
