edwardian round bay window - cracking & dropping brickwork arches

The subject building is a substantial traditionally built Edwardian building on two floors below a pitched tiled roof.

 

This period property required sympathetic treatment by Action wall ties specialised staff. Cracking and dropping brickwork was stabilised with stainless steel bed joint reinforcement and wall ties. The round structures and brick arches were reinforced and the surrounding structure made good in keeping with the appearance of the property.


Detailed Case Study

 

Defect   


Action Wall Ties investigated and reported varying stages of distortion, cracking and dropping of brick arches, along with some cracking to the brickwork above together with many previous attempts of repairs to the round bay windows

Causation

 

Action Wall Ties reported that the movement noted was believed to be progressive due to a combination of ageing, seasonal moisture, thermal expansion and contraction (i.e. hygro-thermal) resulting in ineffective support from the existing arches allowing the brick arch to spread drop and the brickwork above to crack.

Solution

A long term, cost effective solution was provided by Action wall ties' highly skilled operatives. The existing appearance of this period property was carefully maintained. The works were designed to minimise the disruption to the building's occupants and minimise the impact on the environment  

 

Greater London, Essex, Sussex and Kent are all covered by the professional services of Action wall ties.



Our remedial scheme involved introducing Bed Joint Reinforcement Beaming Fenestration lintel repair and install resin bonded ties to reinstate the uniformity of the wall and providing restraint.


As indicated with red double dotted lines on our proposal 1 & 2, we introduced two rows of twin stainless steel corded joint reinforcement forming a deep masonry composite  beam all round the bay.

 

As indicated with green parallel lines on our proposal 1 & 2, to the underside of the fenestration openings head, we drilled for and install either grouted or driven 9mm helical stainless steel pins through the brick arch and passing into the line of the deep masonry beam, installed within the existing masonry.


 

As indicated with red stars on our proposal 1 we drilled for and resin bond new 9mm stainless steel remedial ties re-point disturbed areas.
