Lintel Failure is a common defect to period properties and cracking and sagging of the masonry is a serious structural defect that should not be ignored.
To restore the structural integrity of the masonry Newman Building Solutions designed a specification that would allow the installation to be carried out in a day but also restore the integrity.
Deep masonry beams were installed above the lintel distributing structural loads and the brick lintel was propped back into position and resin injected creating a load bearing high strength lintel whilst restoring the original aesthetics of the building.
As well as lintel failure a 3mm crack was stitched using 1.2m single crack stitching rods where cracking had occurred caused by a change in loadings where lintel failure had occurred.
With the introduction of the Twistfix heliforce system we were able to restore the structural integrity of the masonry. Twin 6mm helical rods were inserted into the bed joint crating masonry beams tying the bay window back to the main structure and distributing structural loads. Twistfix pinning ties were inserted vertically through the lintel tying them to the masonry above. We used 8mm lateral restraint ties installed through the external masonry tying into the floor joists.
Cracking to bay windows is a common defect to period properties that should not be ignored. Traditional costly, disruptive and time consuming methods should be avoided when you can utilise modern methods of masonry repair.
Newman Building Solutions were contacted by the owners of this 16th century farm house as they needed advice and costing for the refurbishment of the external fabric of the building as well as improving the security and kerb appeal.
The external rubble filled walls were found to be suffering from delamination so Twistfix delamination grout ties were installed at 450mm x 450mm centres in addition to delamination ties the corners of the property were reinforced and stabilised using 2m long cementitious sock anchors installed at 600mm staggered centres cross pinning the walls.
Deep bed repointing to various areas was also required using a specialist lime mortar.
The main entrance of the property was made secure by constructing two 6ft high solid stone walls with 10ft x 6ft hardwood electric gates and new close board fencing.
