Wall Tie Replacement in Surrey

The highly-regarded Twistfix-registered contractor Newman Building Solutions have successfully completed another project using our products. Working with their client, a national firm of loss adjusting engineers, Newman Building Solutions were requested to undertake a structural survery of a single-storey bungalow in Guildford, Surrey. The survey revealed that the masonry of the building was unstable and furthermore revealed inadequate wall ties which had failed. In addition, much of the pointing had come loose.

Newman Building Solutions designed a structural repair specification and specialised programme of stabilisation. This began with wall tie replacement; Twistfix supplied their unique 9mm Airtwist CD wall ties, which were installed at 900mm x 450mm centres through a pilot hole of just 6mm, utilising a dry-fix method. This method is a quick and highly effective wall tie replacement scheme which gives good structural integrity and prevents any further movement. Several pull-out tests were carried out at selected intervals and the lowest-pull out was recorded at 1.2kN, some 4 times the load required for the building.

Once structural integrity was restored to the building, focus turned to the areas that required repointing. These were raked out utilising conventional grinders with dust extraction, to a total depth of 35mm. Using thixotropic cementitous grout injection, a 10mm recess was left behind for repointing which provided a well-hidden repair to the structure.

Newman Building Solutions carried out all of this work to their usual high standard and the wall tie replacement scheme was warranted for 25 years. This provides a long-term insurance-backed guarantee that is regarded as the best available within this industry and is reflective of the superior quality of both Newmans' professionalism and Twistfix's products.
