Cracks in walls are not uncommon in Australian houses – occurring in both outside brickwork walls and inside plaster-board and rendered walls. When sinking of building footings supporting the wall is a cause, raising and stabilising may be needed.
Footings can sink when they loose support from the foundation ground. Years of drought and subsequent heavy rainfall in Australia can affect soils containing reactive clay. The clay shrinks and the house can loose support. This can cause parts of the footing to sink and wall cracks to appear.
Re levelling sunken floors and foundations assists wall cracks to close up, windows and doors also begin to work properly again as sunken footings and floors return back to their correct levels. The process of raising, re-levelling and re-supporting a house is called ‘underpinning’. When Underpinning is required Mr Crack employ the most efficient and no fuss method on the market:
