simple horizontal - Sagging Window Masonry at Risk of Collapse

The masonry at the font of this mid terraced home near Croydon, London, was sagging in the middle due to a failing bressumer support beam above the bay window. The distortion was clearly visible outside the property, with the distortion of the windows giving it a cartoon-like sad expression. Inside the property the floors were sloping and walls and ceilings cracking.

The structural problem had progressed so far that it was bowing the main roof of the property. Without suitable structural repairs the property was at risk of collapse.

Traditional building works to repair such a serious structural fault would have required a major building project. Standard building methods would require de-construction of the front elevation, replacing the beam, rebuilding the front first floor brickwork, refitting the windows and re-plastering inside.

This Victorian/Edwardian home in South East London had clearly visible structural distortion:

  • Significant visible distortion of the front elevational masonry
  • Dropping of the centre column of 1st floor brickwork
  • Significant deflection to the window openings, cills & lintels down to the centre of the building
  • Bowing of the main roof
  • Cracking to the internal plaster
  • Bulging of the ceiling

The AWT survey team rapidly diagnosed a failing bressumer beam. Bressumer beams are also known as bressummer beams, breastsummer beams, summer beams or jetty sills. These large timber beams span openings, such as bay windows, and support the masonry above. Failure of a bressumer beam, due to deterioration of the wood or movement within the structure, can have serious knock on effects for the building’s structural integrity.

This was a serious structural defect significant and if it was not addressed it would result in the ultimate failure and collapse of the structure.

The Structural Repair Solution

AWT were called in to find an alternative to slow, expensive and disruptive rebuilding works. AWT have spent many years developing equipment and methods that allow structural repairs to be carried out that treat the root causes of the problem without demolition and rebuilding. This allows a less disruptive, more cost effective repair solution.

AWT’s structural repair plan included:

  • Installating temporary supports
  • Using AWT designed equipment to realign the bressumer beam, floor joists, brickwork, window cills and lintels
  • Removal of the existing timber bressumer beam
  • Formation of concrete pad stone supports
  • Installing a new steel beam
  • Masonry beaming – reinforcement of the brickwork using Bed Joint Reinforcement
  • Restraining bulging masonry by installation of resin bonded ties within the brickwork
  • Concrete and brickwork repairs
  • Matching replacement bricks, pointing style and mortar mixture for texture and colour

The property owners plan to replace the old, distorted windows in the future to complete the transformation.

AWT left the property with hardly a sign of the extensive works visible on the outside of the property. Inside, there are no visible fixings. The disturbed areas of internal wall and ceiling were left ready for replastering and redecoration. As can be seen in the photos, the internal finishes have been disturbed far less than would have been the case after repairs by traditional techniques.
