Crack Stitching Project

Construction – Solid 225mm brick wall

Remedial action

Crack stitches are usually installed in every third or fourth joint (or as specified by engineer) as shown on the photo above. They are generally 1m long (ie to extend 500mm either sided of the crack) and, in the case of the Joint Remedial Anchor system, are installed 50mm into the joint.

Wall stabilisation - wall strengthening project

Construction -  Solid brick built boundary wall 340mm thick x 1.2m high with a concrete capping.

The Problem:

This was an unusual project. The boundary wall to this parking area was being damaged by vans as they drove in and out. The local residents would not allow the wall to be removed or rebuilt, so it needed to be reinforced to withstand the abuse of the vans.   

Wall Strengthening Actions:

The capping was temporarily removed and anchors were installed vertically (at a slight angle) every metre.
