Ansan, South Korea
Homeplus, a Korean discount store retail chain (owned by Tesco) has 113 branches throughout South Korea and is the second largest retailer in the country. This project included a large retail store and parking area on the roof of the building. Initially, a membrane solution was specified for waterproofing of the structure, but turned out to be unsuitable due to the projected volumes of traffic and future repair issues.
PENETRON ADMIX was used to treat 1,905m3 (2,492yd³) of concrete for the rooftop parking structure. All construction joints were sealed with PENECRETE MORTAR and PENETRON. The comprehensive success of this solution led to the use of the PENETRON technology on two additional rooftop parking structures; the Homeplus stores in Kyeongsan and Busan City.
