Structural anchoring

Peter Cox are specialists at using structural anchoring and reinforcement systems, providing solutions for structures, including historical buildings, masonry bridges, monuments, railway structures and walls. Masonry anchors can also be used to create secure fixings on facades, walls and structures providing a solution to fit your project.

The mechanically grouted masonry anchors use a sock system to stabilise damaged masonry, with the sock expanding to form a strong bond. These are purpose designed for each project or application, and are highly versatile. They are highly effective in poor quality materials, and for bridging cavities in walls or structures. The versatile nature of this product means it can be used for a vast array of projects, as it can be customised to any specification.

The anchoring system can be used on an array of materials, from stone, concrete, clay, terra cotta, adobe and even timber. It can also be used underwater and in weak substrates.

The structural anchoring and reinforcement installation process

  • Drilling: - Installation holes are created in the masonry using a wet diamond drilling process with extra drill bits added as required to achieve hole depth.

  • Inserting anchor: - for stabilisation work anchor lengths are typically 1-11metres in length. Its essential that care is taken so the polyester sock surrounding the stainless steel bar isn't punchered.

  • Injecting the grout: - The cementitious grout is site mixed and then sieved before pouring into a pressure pot, operating between 2 and 4 bar. The grout is forced into the sock around the anchor, filling out the cavity that's been drilled. The grout will begin to harden are approx. one minute.

  • Anchor sections: - The grout is injected through the rod using hollow section anchors. When solid single or multi bar sections are used, a separate injecting tube is inserted into the fabric sock. Threaded rods can be used to facilitate fixing attachments to the anchor head - for tie bar extensions or support brackets.

  • Surface repair: - Drilling holes are covered, meaning that the repair will be almost invisible - perfect for work done on historic buildings or structures.

The Cintec reinforcement and anchoring system is comprised of a stainless steel bar surrounded by a woven polyester fabric mesh sleeve into which a specially formulated cementitious grout is injected under pressure. The flexible sleeve expands and moulds itself into the spaces within the wall, providing a strong mechanical and chemical bond when cured. Various attachments can be welded to the anchor head. Cintec masonry anchors are purpose designed for each project or application, and are highly versatile.
