We used DELTAShield HP 400 and applied it using high-pressure, heated, plural-component spray equipment. DELTAShield HP 400 serves as an exceptional primary and secondary containment membrane, delivering seamless, instant-curing, and flexible containment solutions that surpass the performance of standard waterproofing membranes. It is the ideal lining for abrasive liquid containment, as well as industrial, chemical, and high-impact applications.
