Brick and Mortar Repairs Perth

What is mortar? 

Mortar is a thick mixture of sand, water and cement that serves as a long-lasting and durable bonding agent for brick, concrete block and other masonry products.

What is fretting mortar?

Fretting mortar is the process by which a structures mortar joints (the mortar between the bricks) begin to break down; it crumbles and falls away.  The fretting is caused by damp issues such as rising damp, weathering and even reticulation/sprinkler systems or the result of excessive salt in the mortar or other unsuitable mortar mixes.

What is mortar joint repair?

Brick is a valued exterior for many structures because of its attractiveness and low maintenance.  However, over time, water and seasonal expansion and contraction attack the solid mass of a brick wall at its weakest point – the mortar joints.  The mortar joints deteriorate wherever water reaches them including under windows and walls, around chimneys, behind downpipes, at ground level and exposed wall tops creating an unattractive exterior, diminishing brick quality and an unsafe structure.  Mortar joint repair is the repair of eroding and cracked mortar joints, often called pointing, repointing or tuck pointing.

    What are the main causes of mortar defects and/or cracks?

    Some of the main causes of mortar defects include:

    Poor Workmanship

    Incorrect mixing ratio of products and poor workmanship on the initial mortar application on structures which are subject to frequent moisture will promote deterioration.


    When a structure settles it transfers stress to the structure above it.  Parts of a structure settle differently causing stress on that particular portion, mortar being one of the weaker joints on the structure’s interior will crack and peel allowing moisture to penetrate.

    Exposure to harsh environment

    Sulphate attacks, over exposure to moisture and thermal expansion all cause mortar to fail.  Coastal areas, that are exposed to salts/sulphates can be particularly vulnerable as the salt crystals stick to the brick surface and eat away at it; this damage accelerates deterioration.

    How do you repair a brick mortar joint?

    In order to complete the repair, the mortar must be replaced, this process is often referred to as repointing.  Repointing is completed by cutting or raking out the fretted joints and replacing them with a correctly mixed mortar.  While the repair is straightforward, we recommend a professional complete the works.  A professional is well aware of the mixing ratios of the mortar products, is experienced in the gradual removal and replacement of the defective mortar without destabilising the structure entirely and can be relied upon to colour match accurately.  A professional provides the attention to detail that is necessary for a seamless repair which easily distinguishes between a professionally completed job as opposed to that completed by an amateur.
