Problem:<br />
Cement based products used in the past to seal around chemical storage tanks continued to crack <strong>and</strong> fail.<br />
A seal needed to to be maintained to eliminate chemicals from seeping <strong>and</strong> contaminating the<br />
underground. The seal needed to resist chemicals such as Cyanide <strong>and</strong> remain flexible to withst<strong>and</strong><br />
thermal cycling (cold winters <strong>and</strong> warm summers).<br />
Solution:<br />
<strong>Repair</strong> areas were hydroblasted to remove loose concrete <strong>and</strong> clean contaminates. Cracks <strong>and</strong> joints were<br />
filled using a polypropylene backer. This prevented the Flexane 80 Liquid from migrating deep into the<br />
concrete. Crack <strong>and</strong> joint surfaces were then primed with FL20 Primer. FL20 Primer was allowed to cure<br />
or dry for 15 minutes. Flexane 80 Liquid was mixed <strong>and</strong> transferred into dish soap bottles for ease in<br />
dispensing. Following 4 months of service, no failures were visible.
