Movement / Expansion Joints

Maystone Structural use modern methods of repair to build vertical movement joints into masonry structures.

Movement in masonry cavity walls can be caused by a combination of actions including expansion and contraction of the substrate resulting from the effects of moisture within the masonry units, temperature variations, expansion that occurs as clay bricks age or by shrinkage that occurs as concrete blocks/bricks age, the distribution of openings and restraints will also influence the build up of stresses and subsequent movement.
Movement joints should be provided to control expansion and contraction and avoid unsightly cracking. The joints should be properly constructed to cater for the calculated degree of movement without reducing the stability and weather-tightness of the wall.

Our teams will cut slots at predetermined locations within the structure and stabilise using structural bars and de-bonding sleeves. This will allow the fabric of the structure to freely move under natural expansion and contraction without causing damage to the buildings facade.
