The principal contractor on the essential maintenance works was Mulalley & Co. Ltd., who are based in Woodford Green, Essex. Mulalley is a highly-respected, family-owned construction business that was established in 1972 and carries out a broad spectrum of work to both new and existing housing, education and social developments. Catering to the needs of major companies and organisations, Mulalley continue to cement their reputation as a construction company of distinction.
After completing a survey of the two 7-storey blocks, which were constructed using dense aggregate block housed within a concrete frame and featuring brick façades, surveyors from the Council discovered a major lack of wall ties and put forward a remedial solution. This involved installing 6,100 stainless steel replacement wall ties, a solution that would take a team of 3 installers - one man drilling and two driving in the ties - around 10 days to complete.
The 9mm x 205mm helical CD ties from Twistfix were simply and quickly driven into pilot holes in the masonry walls utilising the impacting action of a hammer drill. Each tie further strengthened and stabilised the structure as the work went on, delivering a fast, efficient and cost-effective cavity wall tie system that, in line with the strict requirements of Haringey Council, carries a Twistfix 20 Year Product Guarantee Certificate.
The ties have been granted full CE Marking approval for use in brickwork, blockwork and concrete. They can be successfully used in a wide range of masonry wall types including in difficult to fix substates such as aircrete and perforated bricks; the unique SDS setting tool ensures safe drill operation throughout. As they are so efficient, Thor Helical Twistfix CD Ties have grown to become the best-selling remedial wall ties on the market today.
