This was due to being sited on Class \u201cH\u201d soils (under AS2870) and subsequently large degrees of seasonal swelling\/writhing of the clays on which its foundations were placed.<\/p>\n<p style=\"text-align: justify;\">Using the <a href=\"https:\/\/atconsulting.com.au\/retroclay\/\">Retroclay\u00ae<\/a> system developed by Airey Taylor Consulting, the design and build team were quickly and inexpensively able to treat and permanently prevent further damage caused by clay movement. The\u00a0 system artificially expands the structural footprint of the building, then raises the moisture content of the clays beneath this footprint to their maximum swell, locking in this swell and preventing any further movement around the perimeter causing cracking to the structure above. Repairs\/remediation could then take place to the permanently stabilised buildings.<\/p>\n<p style=\"text-align: justify;\">In this case, the 35 individual buildings were inexpensively treated and permanently remediated from\u00a0cracking using this technique.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Inexpensive remediation of 35 individual buildings in $232 million complex affected by clay movement on Class H Soils using Retroclay system<\/p>\n","protected":false},"featured_media":5555,"parent":0,"template":"","meta":{"_acf_changed":false},"dt_portfolio_category":[124,89,96,117],"featured":[87],"class_list":["post-5554","project","type-project","status-publish","has-post-thumbnail","hentry","dt_portfolio_category-claylock-retroclay","dt_portfolio_category-educational","dt_portfolio_category-innovation","dt_portfolio_category-remediation","featured-featured"],"acf":[],"_links":{"self":[{"href":"https:\/\/atconsulting.com.au\/_staging\/wp-json\/wp\/v2\/project\/5554","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/atconsulting.com.au\/_staging\/wp-json\/wp\/v2\/project"}],"about":[{"href":"https:\/\/atconsulting.com.au\/_staging\/wp-json\/wp\/v2\/types\/project"}],"version-history":[{"count":0,"href":"https:\/\/atconsulting.com.au\/_staging\/wp-json\/wp\/v2\/project\/5554\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/atconsulting.com.au\/_staging\/wp-json\/wp\/v2\/media\/5555"}],"wp:attachment":[{"href":"https:\/\/atconsulting.com.au\/_staging\/wp-json\/wp\/v2\/media?parent=5554"}],"wp:term":[{"taxonomy":"dt_portfolio_category","embeddable":true,"href":"https:\/\/atconsulting.com.au\/_staging\/wp-json\/wp\/v2\/dt_portfolio_category?post=5554"},{"taxonomy":"featured","embeddable":true,"href":"https:\/\/atconsulting.com.au\/_staging\/wp-json\/wp\/v2\/featured?post=5554"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
