Salts causing damage to brick walls from rising damp

Significant damage to bricks to external walls of this house above the damp-course barriers.


Inadequate damp-course barrier that should have extended flush with the brick face, during construction of the house.


  • Support the brick walls, removing bricks, fitting of physical damp-course barriers then relaying the bricks. Highly effective but labour intensive and costly.
  • Drilling and injecting chemical damp-course barriers into the brick walls.
