Brown Rot had taken hold in the horizontal load bearing timber beam in the front bay window of this home in Hither Green, South East London. The rot had also spread to the adjacent cantilevered floor joists.
The beam and joists were no longer strong enough to support the weight of the building. The bay window area of the property was becoming unstable. The brickwork was cracking and bulging.
Action Wall Ties acted quickly to firstly stabilise the structure to prevent further movement.
Before installing temporary supports and starting to uncover the Bressummer beam AWT installed Bed Joint Reinforcement Beaming both externally and internally. Box beams were also installed.
Bed Joint Reinforcement Beaming requires precision drilling and injection of stainless steel bars and Cementitious grout into the brickwork. No fixings are visible once the work is complete. Re-pointing with colour matched sand and cement mortar gives a neat finish.
This vital work redistributed the upper storey loads to those parts of the supporting structure which were best able to carry them. It also assisted in restraining any further diagonal cracking and bulging of the brickwork.
When the temporary supports were in place the bay window beam and rotten floor joist were replaced. With the structural integrity restored, this property can now continue to be a home for many years to come.
