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 Building Solutions regularly carry out lintel failure surveys in order to establish the extent of lintel failure and the risk it poses.
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.
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 Building Solutions 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.
At Newman Building Solutions we utilise modern methods of masonry repair to restore bowing walls and lintel failure to name but a few structural defects.
Our specialist services were called upon by a building surveyor managing the refurbishment of a Victorian built 1890’s semi detached house in Croydon, South London.
After completing our survey it was discovered that there was extensive outward movement to the front and gable elevations and with the loft conversion in progress the additional stress to the masonry was sure to cause severe movement.
Over 30 Lateral restraint ties were used on the gable elevation alone into the first floor and the new loft floor to restrain the outward movement combined with bed joint reinforcement ensuring there would be no further outward movement.
With the bed joint reinforcement being installed front the front elevation wrapped around the gable and into the rear elevation the lintel failure was repaired and the bowing restrained.
The pick of today’s Structural Surveys was to this large Manor house in Shepperton. The property is undergoing major repairs to the external fabric and the client had concerns over some suspicious cracks above and below some of the windows, after a close inspection it was found that the property had suffered from Lintel failure to a number of the windows. Our repair scheme will include the installation of deep bed helical masonry beams using the Twistfix system 450mm CD dryfix pinning ties will also be installed along with grout and resin injections to various areas, once all Structural Repairs are complete the brickwork will be repointed using a hydrologic lime mortar.
