Sika wrap solution for Scottish Academy
columns
SikaWrap Hex-230C carbon fibre fabric system used to confine and strengthen concrete columns that support the first floor cantilevered section of Annan Academy in Dumfries and Galloway in Scotland.
Deterioration of the concrete over this 40 year period had weakened the structure and additional, substantial propping had been put in place to ensure the integrity and safety of the building SikaWrap Hex-230C was chosen by Design Services, Dumfries and Galloway Council's in-house consultant in conjunction with their sub-consultant Mouchel Parkman, as the ideal solution to return strength to the concrete columns with as little visual impact as possible
