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.
Newman’s surveyors have carried out 2 interesting structural repair surveys today in London.
The first survey today was to two houses built along the edge a canal in west London. The movement is established as historic settlement causing cracking to the brickwork and altering the load paths resulting I diagonal cracking above the lintels indicating brick arch lintel failure. In order to restore the failed lintel masonry beams well be installed along with 450mm pinning ties installed vertically through the lintel.
Brick arch lintel failure
The second survey in London was to identify the cause of cracking to this grade I listed tower in central London. The tower is built from 13 inch solid brick work and had substantial areas of cracking. The cause of cracking is a combination of ground settlement, lintel failure and brick damaged caused by freeze thaw cycle. In order to repair the masonry over 1500 metres of helical bar will need to be installed.
Newman’s are currently undertaking brick repairs to a grade II* listed building as part of a complete refurbishment of the external fabric of the building.
The building in Blandford town centre was constructed in the early 1800’s and originally used as a pub having changed ownership and use of the building had changed from pubs, restaurants to shops and now a cafe is being adapted into a national chain of opticians.
Brick Repairs
We were contracted by a brewery of whom we regularly carry out repairs, to act as a main contractor to design a scheme of aesthetical and structural repairs.
The lime mortar was suffering from failure with many areas of missing and loose pointing requiring reinstatement. Using specialist lime mortars sourced locally all areas are being repointed, cracked bricks are to be repaired and structural cracks reinforced with bed joint reinforcement.
We are a specialist in undertaking works involving listed buildings and are able to provide consultancy, design and installation.
