Movement Joints-Thermal Cracking

Movement Joints – Thermal Cracking

Movement Joints

London Structural Repairs were asked by a structural engineer consultant to create a movement joint to a property in South East London, which was suffering from thermal cracking. Our skilled operatives cut a slot in the brickwork and made good the surrounding bricks then used backing foam and appropriate mastic to create the movement joint.

Movement joints are often required to provide a break in extensive spans of masonry or in instances where Thermal Movement has caused extensive structural damage which requires remedial Movement Joint installation.

Thermal Movement is a growing cause of concern with our ever changing weather having adverse effects to our masonry by causing the expansion and contraction of masonry.

Bricks and mortar have extremely high compressive strength and can with stand extremely high downward forces but unfortunately bricks and mortar are relatively low in tensile strength so under expansion and contraction unfortunately the structural integrity will be lost.

Thin vertical cracking will appear and if Movement Joints are not installed unfortunately further cracking will occur which could result in catastrophic loss of structural integrity.

The introduction of Movement Joints is carried out by cutting a slot through the external skin of masonry to a predetermined width with horizontal slots chased into the mortar for the installation of slip ties in cavity walls.

Movement Joints consist of a foam backing cord installed in between the masonry previously cut and slip ties installed to resist against wind forces ensuring that structural integrity remains whilst the Movement Joint installation remains.

Bay Window Repair - Reinforcement

Bay Window Repair – Reinforcement

Bay Window Repair

London Structural Repairs have completed bay window repairs to a property in Marlow just outside of London.

We installed Helical bars to the right hand side junction of this period property to stop any further cracking and to stop water and moisture entering the property ruining internal decoration. Bay windows are a common feature in period properties and they can pose severe structural defects leading to cracking, which can cause major stability concerns, ingress of moisture and lower the value of your property.

Bay windows commonly fall into a state of disrepair and in order to bring an aesthetically pleasing redecoration programme you may also require structural reinforcement, to repair any cracks and stone damage.

Common structural defects are often lateral stability issues, lintel failure and a combination of stone erosion and failed pointing mortar. Combined with very shallow foundations it is often very common that bay windows will suffer from severe cracking at the junctions between the main house walls and the bay window.

It is essential that reinforcement is installed and a combination of masonry reinforcement along with lateral restraint ties in order to restrain and prevent further cracking whilst providing a concealed method of repair.


Structural Repairs South London

Structural Repairs South London

One of our recent projects on a victorian house to carry out structural repairs South London

London Structural repairs carried out a variety of structural repairs South London for a private property developer.

The property was a period property that was suffering from bowing walls on the side elevations of the house and there was also cracks in the property that needed remedial crack stitching works carried out.

We were asked to strip the house bare internally for the client before carrying out the remedial Structural Repairs, removing all plaster from the walls and ceilings.

LSR provided a full Structural survey and designed the remedial solutions for the properties defects.

Lateral Restraint ties were installed to the bowing side elevation walls, connecting to the floor joists to stop any further outward movement of the wall.

Bowing walls outward movement in most cases is due to insufficient lateral restraint, tying the wall to the ceiling and floor joists. Without these lateral restraint ties the building is vulnerable and with the continued outward movement the building is at risk of collapsing.

Carrying out essential structural repairs will protect your investment

Helifix bars were installed to all external and internal walls where cracks were present this is known as crack stitching.

Cracks In buildings can develop for a number of different reasons. It is important to diagnose the root cause of the cracking in order to be able to recommend the correct crack repair method.

Masonry repairs in London

London Structural Repairs LTD are Masonry Repairs experts providing a wealth of knowledge and services to our clients in and around London. Masonry Repairs can cover a wide range of services and LSR cover them all.

This is one of our Masonry Repair projects in London.

Our client had recently purchased this property and contacted us having already had a structural survey completed, with recommendations to some Masonry Repair works to be carried out. When you have a Structural Survey the survey can be quite vague as to what remedial works are required, thats why it is important to get in touch with a structural repair company if any remedial works are recommended who have the knowledge and experience to provide a repair solution.

This particular building needed Masonry Repairs carried out as it was suffering from cracks to a side flank wall, a bowing flank wall on the opposite side and also cracks in and around the front Masonry Bay Window. The client was intending on doing a full rip out and refurbishment to the inside of the building but needed to have the Masonry Repairs carried out first.

LSR started out by dealing with the side flank wall with the cracks in it. We cut out and replaced the cracked bricks and installed crack stitch bars to strengthen the wall.

LSR are one of Londons leading Masonry repairs specialists.

We then carried our the Masonry Repair works to the Bay Window. Masonry Reinforcement was installed to to the ground floor and 1st floor bay window and the external masonry was reattached to the internal joists with the use of drive pins and then all the chases and making good to the bay window was carried out with the use colour matched lime mortar.

Our last job on the property was to install Lateral Restraint ties to the bowing flank wall. lack of lateral restraint is a common fault on period properties and the works are to reconnect the the internal floor joists to the outer walls to stop any further movement. The works are usually carried out from the outside of the property but on this occasion we had to install straps instead of ties as the flank wall was to close to the next door neighbours property. LSR lifted floor boards and cut out pockets in the masonry and used a non shrinking grout to hold the straps into the pockets as well as noggins in-between the floor joists.

Cracks above windows and doors

Cracks Above Windows and Doors

Has your property got Cracks Above Windows and Doors ?

This is one of our recent projects in south London. The property was a period property suffering from cracks above windows and doors. LSR had to work on the masonry above a set of patio doors and two windows. London Structural Repairs installed masonry reinforcement beams and pinning ties to stabilise the brick arch lintels and then made good the pointing and cracks to a near invisible repair but with a bit of weathering will become a perfect repair as seen from the photos below. This type of repair method is quick, cost effective and non disruptive to the residents of the property.

Cracks above windows and doors are usually caused by failed lintels. This a common fault on Victorian and Edwardian properties as the brick lintels known as boot lintels do not span across the opening into the main wall of the house as modern lintels do taking the load of the brick work above it.

Lintels are usually made up of bricks, concrete or steel and also it is not uncommon for us to come across timber lintels. When the lintels fail you get cracks above openings and this is usually because of window replacement, eroded mortar joints or if in London we come across it to be bomb damage from world war two frequently.

Have your Cracks Above Windows and Doors looked at by our experts

Bowed Wall Repairs

Bowed Wall Repairs

Is Your Victorian or Edwardian Property in need of Bowed Wall Repairs in or around London?

Bowed or bowing walls are a common defect on period properties due to inadequate degree of horizontal restraint between the external walls and the floor structure, causing the need for Bowed Wall Repairs.

A wall being out of alignment is a common defect with high walls of older properties. In modern houses there is a physical connection between floor joists and roof joists using proprietary galvanised metal straps built into the wall and fixed to the joists at floor and roof level. However in period properties there was no such a requirement. Where the joist span perpendicular to the wall and bear into the wall there is a limited degree of restraint due to the friction between the built in joists and the wall surface but this can deteriorate over time. Where the joists span parallel to the wall there is no lateral restraint offered to the wall, usually the side gable wall and this is where bowing usually occurs.

Why Not Have A look At Our Services Page

London Structural Repairs Are Experts at Bowed Wall Repairs

This is one of our recent projects where we carried out Bowed Wall Repairs to an Edwardian property in the heart of North London. The property which was going to be refurbished inside and out was bowing outwards on the front, back and one of the side elevations, so the order of the works was to carry out the Bowed Wall Repairs first to restore the structural integrity. London Structural Repairs had our surveyor carry out a detailed structural survey to the property and then designed the repair strategy to fix this common defect.
