Another of today’s Structural Survey to investigate a bowing wall on this 1902 block of flats in Knowle, Bristol.
The bulge in the flank wall measures approximately 3.5 metres by 4.5 metres and is due to separation between the inner and outer leafs of masonry, after carrying out our comprehensive survey a solution was achieved using a combination of Twistfix helical bars, Twistfix delamination ties and lateral restraint ties together with deep bed grout injection and ‘re pointing eliminating the need to rebuild the flank elevation at a considerable cost.

Tower block construction began in the 1950’s with the first tower block in Britain being built, The Lawn in Harlow, Essex. The need for housing influenced the decision for tower block construction and it boomed.
The Lawn, Essex
Tower blocks are constructed usually using three methods; in-situ, Steel frame with infill panel and pre-fabricated panels. In theory all three methods of construction should have provided structures free from structural defect and with stand the test of time. In reality many high rise structures are in urgent need of refurbishment to ensure they do not enter a state of disrepair with the only solution being demolition.
With all three methods of construction there are common structural defects found that are often similar across the country. Cracking is usually evident within the external and internal fabric of the structure and the defects are often linked to one or more of these causes of movement, thermal movement, lack of movement joints and failed wall ties or inadequate wall ties. Poor construction methods during the build phase. Concrete failure as well is a common structural defect found which can be caused by many factors such as oxidisation of the reinforcing steel, the reinforcing steel being too close to the surface of the concrete which again causes oxidisation freeze thaw action and chemical reaction to name but a few.
