Bridge Inspection and Bridge Repair, North London

We are currently carrying out a structural inspection and repair to a brick built railway bridge in North London.

Our client expressed concerns over the visible cracking and bowing present to the structure of which carries high speed trains into central London so it was vital that we acted quickly in order to carryout the inspection, design and implement a suitable structural repair scheme.


To save time and cost in scaffold we opted to use our van mounted cherry picker that will enable our installation to be carried out rapidly, in less time that it would take to erect scaffolding.

The spandrel is suffering from de-lamination causing in some brickwork to fall from the masonry arch severely weakening the structure. the sofit which carries and distributes the loads of the masonry arch was showing signs of racking caused by vibration allowing water to penetrate into the structure causing defective pointing. the brick pier was also suffering from major cracking and separation.

We will be installing Twistfix helical beams at 300mm centres horizontally accross the masonry arch creating a grid pattern with the bars drilled 1.5m into the supporting pillars providing a reinforced structure distributing the loads. and over 4000 1.5m grout ties will be installed through the sofit into the arch pinning the sofit and preventing further delamination.

the works will be carried out so that the bridge remains fully functional and the road remains open and accessible.

Lateral Restraint Ties & Bed Joint Reinforcement, Solve Another Bow & More Lintel Failure!

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.

Bowing Building 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.

Bed Joint Reinforcement

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.

Lateral Restraint Ties Installed

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.

Rope Access Surveys & Repair

Rope Access

Newman Building Solutions are IRATA accredited rope access trained allowing us to offer a very bespoke package to our clients.

We utilise this method of access where conventional access is either impracticable, due to site conditions or the extensive cost or time implications that traditional methods such as scaffolding or cradle erection impose.

Rope Access compliments our vast array of specialist services and are extremely useful when carrying out surveys to high rise structures.

Tower Block

We are currently carrying out concrete inspection surveys and repair to the largest building in Watford, which is a 14 storey tower block, on behalf of the YMCA. Our recent rope access projects include feasibility surveys in central London, Structural Survey and Repair to 3 tower blocks in Hackney, East London and a Bridge Inspection in West London.

Rope Access Survey

With the councils budgets slashed cost effective solutions to structural inspections and repair solutions are required in order to upkeep the integrity of these streets in the sky. Newman Building Solutions carry out surveys and repairs such as concrete repair, wall tie replacement, movement joint installation, bed joint reinforcement, brick slip repair to name but a few.

If you have a high rise structure that is in need of a survey to assess the condition of the building or the building has been surveyed and is in need of repairs be sure to contact Newman Building Solutions.
