Wall Tie Replacement

follow A common cause of structural cracking and bowing walls is cavity wall tie failure. This can occur due to moisture in the wall corroding the wall ties so weakening them or there are simply not enough wall ties present to support the wall. Wall tie replacement may be required.

What are the signs of cavity wall tie failure?

Wall Tie Surveys

الثنائية ويستعرض الموقع خيار Our structural remedial surveyors use a combination of visual impression and investigatory procedures when carrying out a wall tie survey. A visual inspection will be carried out in the first instance and if further investigation is needed to assess the condition of the wall ties within the cavity wall, then we will carry out an intrusive wall tie survey. This will involve the use of a metal detector to locate the wall ties and via a small hole drilled into the wall, inspection of the condition of the wall ties inside the cavity using a borescope camera.

A thermal imaging camera can also be used to indicate signs of moisture which may be impacting the corrosion to the wall tie.

Installation of Wall Ties

http://irvat.org/index.php?option=com_content A combination of works is usually required in order to install a full wall tie system correctly. Remediation works can involve isolating the failed ties and installing high grade ties made from a non-corrosive material meaning the wall will be left stable and secure for many years to come.

binäre optionen strategie 5 minuten The wall tie installation itself is completed by drilling through the outer wall and into the inner wall usually from the outside of the building. Once the wall ties are installed, random ‘pull out’ testing is carried out to ensure the correct fixing strength has been achieved.

http://www.hamburg-zeigt-kunst.de/?biudet=bin%C3%A4re-optionen-leicht-erkl%C3%A4rt&e4f=28 Wall tie replacement is a technical process and accordingly we use only our own trained and experienced in-house structural repair surveyors and operatives to survey and carry out this work. It is important to note that a structural survey carried out by a qualified Structural Engineer may be necessary in the first instance. We will advise if this is the case.

Other Types of Structural Repairs

watch Re-pointing of brickwork or masonry protection applications such as Stormdry may also be necessary to stop and reduce the amount of moisture that can penetrate through the wall. This is particularly common where soft porous bricks are present.

What are cavity walls?

diclofenac 400mg 80mg Cavity walls consist of two half brick leaves, the inner leaf and the external leaf, usually with a 50mm cavity in-between. The two halves of the wall are tied together using mild steel or wrought iron wall ties spaced at regular intervals to provide the support required to keep the property stable.

lowest price benicar Houses built before 1935 were most commonly constructed with solid brick and no cavity walls but the trend changed to building homes with cavity walls as this gave a cheaper build method and a way to provide more protection from the natural elements and to help improve thermal insulation.

What is cavity wall tie failure?

Since the 1930’s cavity walls were used in the construction of a property to provide more protection from the natural elements and to help improve thermal insulation.

In recent years, the wall ties used to tie the internal and external walls of properties built prior to the early 1980’s can suffer from corrosion as the mild steel or galvanised wire ties embedded in the mortar start to corrode causing wall tie failure meaning the support the wall tie provides between the inner and outer leaf is reduced.

New build properties are being found to require supplementary wall tie systems where insufficient ties have been implemented or omitted altogether in the build process.
