Cavity wall tie corrosion can leave the walls of your home with severe cracking, bowed and in an unrestrained, dangerous condition. For this reason, assessing the condition of your wall ties is a duty which must only be undertaken by an experienced and qualified surveyor.
Our cavity wall tie condition surveys are undertaken by our own experienced and qualified surveyors who have been independently trained and examined by our leading industry bodies ensuring their knowledge and expertise. Our surveys are conducted in accordance with British Standard Codes of Practice and industry guidelines.
In most circumstances our surveyors will carry out non-invasive cavity wall tie inspections using specialist optical equipment. We aim to undertake our inspections within the cavity of the wall using borroscopes, which provides us with a mid-section view of the tie and the tie bearing into contact with the walls. Where cavity wall insulation is present however, this may obscure our view. In such circumstances, it may therefore be necessary for us to chase out the tie ends in the wall or remove a brick to expose the ties.
Our survey procedure is undertaken in accordance with the guidance recommended in Building Research Establishment Paper 401 "Replacing Wall Ties"
After locating and inspecting a series of ties, our surveyors will assess and determine their condition and remaining life span, following the BRE guide "visual grading the condition of steel ties".
Our findings are recorded and assisted by photographic evidence of our onsite inspection which is included within our report.
Our reports are bespoke and contain a comprehensive assessment of the problems identified during our survey including our diagnosis, damage appraisal, recommendations, repair specifications and costs for repairs, if necessary.
Edited pictures along with category damage ratings are also included to assist your understanding about the urgency of any repairs needed.
Our reports are available in both printed media and/or secure electronic portable documents (PDF) for email.
If you suspect a problem and require a survey, or simply need advice please contact us.
