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.
• Vacuum-Excavation 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. It provides a safe and efficient excavation solution where services are known to be present, preventing utility strikes.
• 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.
• Scabbling (Concrete Reduction) – We have used our Brokk 170 with drum planer attachment, to reduce an average of 50mm of concrete from the surface of a circular sloped water tank.
