Please refer to our Technical guides under `SALT ZONES` and salt erosion of clay bricks.
If you have a property situated on the beachfront there is usually some degree of deterioration taking place! All bricks are porous and will absorb salt, and many factors are at play so it is impossible to say how long it will be before deterioration of the façade begins. The softer lime mortar used in external brickwork prior to the 1960's can be substantially affected by salt deterioration. This is more prevalent in the exposed location but buildings located 2-3 kilometres from the sea can also be affected. The mortar becomes soft and powdery.
More recent Calcium Silicate face bricks can still suffer from surface delamination. This occurs as the salt crystals adhere to the brickwork and are absorbed into the bricks. During rain the crystals will expand and then push the outer surface of the brickwork away. Once the hardened surface of the brickwork is lost, then the rate of deterioration of brickwork will accelerate. It is not possible to prevent the surface delamination of bricks.
We have however noticed that the higher temperatured bricks like steel blues are......read more
