Developed in-house at Airey Taylor Consulting, the ClayLock® foundation system was patented in October 2005. It prevents damage to low-rise housing; community, institutional and commercial buildings; rail, road and other civil works built on reactive clay soils.
Conventional foundation design for reactive clay soils resists movement, 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 national problem. A 2005 study of 75,000 houses surveyed by Archicentre in Queensland found an astonishing 38% were cracked, with structures on vulnerable sites nationwide requiring expensive remediation and even replacement.
