Bricks are generally highly absorbent by nature, both clay and concrete. The degree of which is established by how hard the brick was fired in the kiln and on the quality of the clay/concrete. The softer the brick, the higher the rate of absorption. If the brick retains dampness for a prolonged time and the drainage is poor, deterioration in the mortar and bricks can be quite significant. There is also the added factor of a relatively high salt content in the air, affecting structures especially close to the ocean. BrickFix Remedies have a range of waterproofing solutions to protect your brickwork from the harsh Australian elements.
