Rock Drilling

Helping to ensure the reliability and strength of fixings or anchors within masonry and concrete, Pull Testing is an essential safety requirement. With over 30 years of experience and a team of CFA Approved professionals, Castle & Pryor deliver competent work for clients across the UK.

Where We Can Help
At Design Stage − Preliminary / Ultimate Load testing
At the design stage of a project we can provide load testing to a specific rating or to failure to help establish specification of fixing required and allow changes to be made before build/installation stage.

At Installation Stage − Proof Load testing
After installation and to meet build regulations and specifications, fixings and/or anchors will often require inspection and testing by an approved independent contractor. We can fulfil this and attend site at short notice and test a given percentage to ensure design specifications are met. If they pass, we can provide test certificates to allow project sign offs.

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.

Diamond Floor Grinding is an efficient and dust free method of preparing concrete surfaces. The machines use either 415v 3-phase or 110v power and comes in various sizes depending on the application and volume of work. The diamond floor grinding machines have diamond tooling configured beneath the grinding head that rotate in a single or planetary motion.

The operation is clean and fully self-contained allowing sensitive projects to be completed with little or no impact on surrounding areas of work. The diamond floor grinding method is effective on concrete leaving an open smooth profile for products and materials to adhere to.
