Foundation piers can fail for a number of reasons; insufficient footings under the piers, excess water or dampness under the house.
Homes that are built in the period of 1950 to 1990 are normally on one to 2 courses in the ground and with weather patterns after a period of time these foundations tend to move around and fail.
Homes from earlier periods are often lime mortar and these mortar joints deteriorate and turn into powder after time.
Removing and replacing salt affected brickwork can be very time-consuming and tedious. Sometimes replacing work on older homes from the footings to the floor level is unprotected as it has no damp course until floor level.
Other homes built on slabs that are affected I have found over the years are normally on old farmlands and this soil is normally extremely rich in minerals and salts.
Salt damage to these homes is usually caused by poor ventilation in the wall cavities or exposure to chemicals from pool chlorinators, rather than the salt in the pool water itself.
Removing and replacing fractured brickwork is not a very difficult job to do but is time-consuming.
The hardest thing about replacing fractured brickwork is brick matching and mortar matching.
Normally we would replace the fractured brickwork with an expansion joint and do our best to source and match your existing brickwork.
If we find the fracture is new we normally would highly recommend a reputable resin injection company. We also have two companies that we highly recommend.
