We have once again been asked to carry out Structural Surveys in Canterbury, the two properties assessed today are suffering from very similar structural defects.
Structural Repairs
This property has been affected by recent lateral movement due to the masonry having no connection with the floor joists and internal walls, an attempt had been made at some point to rectify the defect by installing traditional tie bars however up on further investigation the tie bars were found to be of little help with a very poor connection to the property.
The property was also showing signs of very early lintel failure which is caused when the external brickwork above the brick arch lintel cracks and the lintel drops.
We use modern and traditional methods
Newman’s structural repair surveyors work with both modern and traditional techniques to overcome building and structural defects. lateral restraint issues are repaired using Twistfix lateral restraint ties combined with Twistfix helical masonry beams.
Brick arch lintel failure can often be repaired without the need for costly rebuilding, once again Twistfix helical masonry beams combined with pinning ties and grout injection ensure all repairs are lasting. Making good using traditional materials and techniques ensuring a close to invisible repair.

Cracking where the party wall or partition wall meets external walls is a common problem caused by a lack of connection between the two walls.
Cross Wall Tying
Often the connection between the two walls is just a cement fillet which provides no connection or protection against outward movement.
In order to tie the two walls together we utilise the twistfix bed joint reinforcement by chasing out the external bed joints, drilling into the partition wall and chasing into the internal partition wall providing an L shaped tie resisting any further movement. The cement fillet is raked out to a depth of 80mm and injected with twistfix cementitous grout providing a permanent solution guaranteed against failure for 10 years.
One of our first survey’s of the week to this listed property in the high street of Maidenhead, Windsor.
The brick tower is suffering from lintel failure and the flank elevation has bowed and cracked due to lateral movement following the demolition of the neighboring building.
Lintel Failure
The brick lintels will be reinforced using Twistfix helical bars and Twistfix 450mm CD dryfix pinning ties, the lateral movement will be stabilised using Twistfix lateral restraint ties install in to the existing parallel floor joists along the flank elevation.
Lateral Movement
Following the structural repairs the new development works will continue as planned, to find out how we can help with your building and structural repair needs contact our head office on 0333 444 0154 or email us enquiries@newmans.com
