Developed in-house at Airey Taylor Consulting, the ClayLock® foundation system was patented October 2005. It stabilises low-rise housing; community, institutional and commercial buildings; rail, road and other civil works on reactive clay soils.
Previous approaches to foundation design on clay have worked to resist movement of these reactive soils, particularly differential movement across concrete slabs. Despite the best efforts of the engineering community and approximately $315 million per year spent on foundational stiffening, cracking remains is a serious problem. A 2005 study of 75,000 houses surveyed by Archicentre throughout Australia found an astonishing 38% were cracked.
