Stonbury Refurbishes Wollaston Water Tower

Posted: Tuesday 2nd March 2010

Stonbury are carrying out a major refurbishment to Wollaston Water Tower in Northamptonshire. Following an extensive structural survey, it was found that substantial repairs were required to the support columns.

Exposure to the elements had left the tower showing signs of distress, with spalling concrete and the degradation of previous coatings and repairs evident on the columns. This led the tower’s owners, Anglian Water to commission term contractors Stonbury to carry out a full condition survey on the entire water tower. This involved carbonation depth testing, chloride sampling, cover meter survey and hammer testing of the columns and bowl soffit and vertical faces.

Following the survey, it was deemed that although the tower was structurally sound, with the 3,183 cubic metre capacity bowl requiring little attention, the support columns needed substantial repair. Stonbury were then commissioned to carry out the refurbishment work to the columns along with a few minor repairs to the bowl soffit.

Fully boarded and sheeted scaffolding was erected and the columns blast prepared. Defective concrete was then removed by breaking out, followed by repair using a specialist concrete repair system. An elastomeric anti-carbonation coating is now being applied to give continuing protection to ensure the future integrity of the structure.
