Specialists in Structural Anchoring

Rentokil Property Care are specialists in structural anchoring and using grout sock anchor systems to help reinforce and strengthen various structures, historic buildings and properties.

We are approved installers of both Helifix and Cintec structural anchoring systems and have vast experience working with structural engineers in order to provide long term repairs.

From our network of local branches we have numerous surveyors and technicians with the experience and expertise to provide structural repairs, no matter the project.

Structural anchoring is a technique of using anchors to provide support and stability to existing structures, help repair damage and can even be used as an anchor for new components. A mechanical anchor can be inserted into a range of different masonry, before cementitious grout is injected into the sleeve, causing the sleeve to expand and bond with the surrounding masonry.

These systems are highly versatile and can be used for different purposes on a vast number of projects. The system is designed specifically for each project, and can be highly effective in historic properties or buildings or structures built using poor quality materials, random stone or rubble filled walls. The mechanical anchors come in various sizes and can be used for bridging cavities in walls and structures.

They are particularly useful for stabilising rubble filled walls, heavy duty and high load applications, masonry stabilisation, arch consolidation and lateral restraints. Depending on the end use, various attachments can be welded onto the anchor head to restrain items such as tram towers or cables.

A mechanical sock anchor is a stainless steel bar surrounded by a woven fabric mesh sleeve which has grout injected into it, once inserted into place. The cementitious grout is injected under pressure into the sleeve, causing the mesh to expand and bond with the surrounding substrate.

This secures the anchor in place, creating a structurally secure system that can be used to stabilise the wall or structure. These anchors are available in multiple lengths, so can stabilise the structure across a wall or from one wall to another across a building.

Structural anchoring is a versatile system, and is purpose designed for each project. They can be installed in weak substrates, poor quality materials and for bridging cavities. Once installed they can be hidden from sight, making them useful for historic or listed properties. These systems are approved by many heritage authorities.

The anchoring system can be used on numerous materials, including stone, concrete, clay, terracotta and timber.

• Stabilising masonry, including solid walls, cavity construction, hollow pot and rubble filled
• Used as lateral restraints
  Replacement and supplementary wall ties
• Crack stitching
• Stitching anchors for arch consolidation
• Stud anchors
• Parapet wall strengthening
• Retaining wall anchoring
• Anchoring of cables back to structures

The first step will be for a trained professional to carry out a survey of the premises in question in order to fully understand the extent of the issue, and the structural repairs required.

If structural anchoring is required, recommendations will be provided in a survey report.

The typical installation process involves:

• Installation holes are drilled into masonry using a wet diamond core drilling process, with extra coring bits added as required to achieve hole depth.
• Anchors come in various diameters and lengths, typically between 1 and 11 metres, but can be longer depending on the size and type of job.
• Once the holes are cut, the sock anchor is inserted into the cavity as cementitious grout is mixed, sieved and placed into a pressure pot, before being injected into the sock under pressure.
• This will fill the sock and expand into the surrounding cavity, before the grout hardens and bonds.

Where required threaded rods can be used to facilitate fixing attachments to the anchor head - for tie bar extensions or support brackets.

For historical or listed buildings, the drilling holes can be recovered with the displaced core, covering up the repair. This will make the repair almost invisible.

Rentokil Property Care has vast experience in structural repairs and are approved installers of both Cintec and Helifix structural anchoring systems.

We work closely with manufacturers to provide expert quality repairs, while our surveyors carry out on-site inspections, attend specialist training and follow best practices.
