In South Australia, many homes grapple with a phenomenon known as salt damp. This condition can significantly affect the structural integrity, value and aesthetic appeal of your home. One of the visible and concerning symptoms of this issue is “fretting bricks and mortar.”

What is Salt Damp?:

Salt damp, also known as rising damp, occurs when ground moisture rises through the walls of a building due to the lack of a working damp-proof barrier. This moisture carries salts, which are then absorbed into the bricks and mortar. As the moisture evaporates, these salts are left behind, causing damage over time.

What Causes Fretting Bricks and Mortar?:

Fretting happens when these salts, known as efflorescence, accumulate and crystallise beneath the surface of bricks and mortar. This crystallisation process causes the surface to break away, leading to the mortar disappearing and bricks chipping off. Not only does this look unsightly, but it can also evolve into a severe structural concern if left untreated.  Apart from the obvious structural risks, fretting mortar can also lead to:

  • Increased vulnerability to weather damage.
  • Higher susceptibility to further salt damp damage.
  • Loss of thermal efficiency in homes.
  • Potential for water ingress, leading to internal damage.
  • Aesthetic degradation, affecting property value.
