cracks in brick veneer house



Cracks in the brick wall of your house are a telling sign that the foundations are failing and often underpinning is required.

Underpinning is a method of restoring and repairing failing house foundations.  The process of underpinning involves digging underneath existing footings in order to determine how much damage has been caused to the foundation.

The process of underpinning begins by manually excavating the soil from beneath an existing foundation. To avoid the risk of undermining the foundation, which may lead to structural failure, the removal of the soil is performed in controlled stages, called ‘pins’, of limited length. The depth of the excavation is determined by a geotechnical engineer, who assesses the soil composition to identify the strata that is suitable to bear the weight of the building. The excavated soil is replaced with concrete, which forms a new foundation beneath the existing one. 

Reasons for an underpinning

  • Leaking pipes
  • Plumbing leaks
  • Poor drainage 
  • Tree root damage
  • Dry soil or evaporation
  • Clogged gutters 
  • Wet soil


House leveling is the process of lifting a home back to the position that it was in when it was new. All houses are built on a foundation. Over time, this foundation can sink, settle, crack, or heave. There are numerous reasons why this may happen. Some common causes are issues with the soil, too much moisture, or a foundation that was not done properly from the beginning.
