Curran Contracting Company
Description of Application
This project included rehabilitation and lining badly deteriorated interior concrete walls. The lining system was selected to address the 2” + deep corroded concrete & miscellaneous cracks present in the partially above-ground walls. The surface was abrasive blasted to fully remove the corroded concrete to result in a CSP 5+ profile. A minimum of 1” of Raven 755 Mortar was spray applied & back troweled to build back a portion of the deteriorated concrete surface. A full prime coat of Raven 175 Primer was applied @ 8-10 mils DFT to lessen outgassing during the topcoat application. A topcoat of AquataFlex 505 @ 125-150 mils DFT was applied in (3) successive applications to insure proper film build & a pinhole-free lining system.
As seen in the jobsite pictures, a “visqueen” tent structure was constructed to maintain climate control during the lining application which occurred in late November/early December.
