Pam Ties

Cavity wall ties are metal strips or rods that are attached into the cavity space between the interior/external walls to link them together. These ties are often made of steel and are given a protective coating to prevent them from corroding. Over time the coating can wear off and the ties will start to corrode which may cause serious damage to external walls.

The most obvious signs are as follows:

  • Cracks in the mortar or a slight separation of cross walls (This is caused by expansion of the wall ties)
  • Outward bulging of the walls (This is caused by corroded wall ties that have snapped – This is a more serious problem as it can leave your property unstable.)

We will carry out a thorough inspection prior to any repair work being started, in order to evaluate the level of damage and provide the most effective solution.  If the cavity wall ties do need replacing, the work carried out will include accessing the existing wall ties by drilling holes into the brickwork and installing the new cavity wall ties.  The existing ties will be isolated to prevent further damage.

If you have noticed any of the symptoms of wall tie corrosion mentioned above, please contact Birch Contracting Services LTD who will be more than happy to take a look and provide treatment if necessary.
