Newman’s have begun a lintel reinforcement scheme for a social housing client in south London to a low level block of flats.
The original timber windows were removed by a glazing contractor who discovered that the brickwork was built without any Intel’s present so upon removal of the frame the masonry above failed causing cracking and sagging.
Helical Rods Are Installed
Twistfix helical rods will be installed between the window openings to repair the masonry and create lintels within the brickwork and pinning ties installed vertically through the last course of bricks pinning it into sound masonry.
Our technicians will be onsite for only one week to allow the glazing contractor to ccarry out their works safely.
The first survey of the day to investigate cracks to the brickwork on this large Victorian property.
Structural defects found include cracked brickwork, outward movement to two bay windows due to a lack of lateral restraints, cracked and sagging brick arch lintels caused by lintel failure.
Our repair scheme will include lateral restraint repairs and lintel repairs using a combination of Twistfix structural repair products as well as masonry grout injection and ‘re pointing.

Lintels come in various designs and are constructed from different materials but all carry out the same task; to support a structure above them within an opening.
Lintel Failure is a common structural defect amongst properties of all ages and constructions and Newman’s regularly carry out lintel failure surveys in order to establish the extent of lintel failure and the risk it poses.
Lintel Failure London
Lintel failure can lead to the collapse of the masonry it is supporting with catastrophic effect. Lintel failure is often recognised by diagonal stepped cracking which is similar to subsidence but should not be confused as subsidence.
Lintel Failure, Diagonal Cracking
Traditional methods of lintel repair are costly and time consuming with many builders believing the only way to restore the structural integrity is to remove the lintel prop the masonry above and rebuild it.
Using modern methods of repair Newman’s can repair lintels by installing Twistfix Helical rods installed in the bed joint above the lintel creating beams above which support the masonry. With fast curing resins lintels can be propped into their original position and fixed saving the aesthetics of the property and time and money.
