Wall Ties and structural repairs presentation for Leeds University estates department

A Presentation to Professionals

Our MD Bryan Hindle was invited to Leeds University last week, to bring a group of Surveyors, Engineers and Architects up to speed on wall tie installation and structural repairs of masonry.

The subject was Wall tie replacement and structural repairs of masonry. Delegates included the University’s team of professionals, who have the huge job of keeping the buildings in the massive campus in good order.

Cintec and Helifix methods were covered, using Bryan’s extensive selection of real on-site case studies, where these techniques using different types of wall ties were successfully applied.

The talk explored the advantages of Helifix’s helical bar repairs, with in-depth information on where and how Helifix’s engineered system can save money and often save historic fabric from demolition. Examples included a Windmill, a historic Yorkshire school and several domestic situations, such as poor lateral restraint of gable walls and bulging and separating barn walls. Helifix’s range of remedial wall ties was dissected in detail.

The Cintec anchor was introduced too, with a couple of Bryan’s videos from sites, showing the sock inflation and testing of these super strong anchors. Diamond drilling, post tensioning of wall ties and tie bars and special applications were explained. Examples included the roof fixings at Westgate shopping mall, Halifax, The York City Walls, Riber Castle and Armley Jail Leeds.

The usefulness of these systems, taken in tandem was covered, as was lime grouting of rubble fill walls, such as that which we successfully applied to Shipley’s Victoria Mill and Woodlesford Methodist Chapel.

More up to date projects were covered too, including remedial expansion joint installation on buildings under ten years old – how and why. Remedial wall ties installed in new build projects, where poor supervision had caused in-built defects – what to look out for – how to avoid these mishaps…

In addition, by special request Bryan passed on some nuggets about Dry Rot in timber. Several myths were debunked and a selection of slides demonstrated the finer points of identification of Dry Rot, its eradication and treatment. The use of timber micro-drilling for detection of hidden decay and infestation was introduced and a Sibtec unit was available for inspection, along with many Cintec and Helifix ties, including a four meter long Cintec Stitching anchor and Helifix’s remarkable BowTie lateral restraint.

It’s fun passing a hour or so with people so interested in the work we do and we are indebted to Leeds University and Ed Batty for the invite.

Our presentations are available free of charge to relevant professionals and interested stakeholders including: Architects, Structural Engineers, Surveyors, Housing Associations and others… please enquire.
