cracks in brickwork – a sign of subsidence

Underpinning a building to prevent further damage caused by subsidence is usually a lengthy and expensive problem for home owners.

The general (and more expensive) method of underpinning houses is to dig 1 metre wide holes (and 1 metre deep) every 2 metres around the property. This method is genereally inefficient as the problem is often within the ground at depths greater than 2 metres.

A system with screw piers as piles overcomes this problem as each pile is installed to a certain depth calibrated by installation pressures. The results of each pile is noted and recorded for the structural engineer. This method guarantees every screw pier has a safe working load to support the building. Installation is much quicker than the traditional riskier methods.
