Plaza Deck Waterproofing

Restoration of existing plaza decks has unique design, performance, and risk consideration.

Plaza deck restoration can cause huge disruptions and creates potentially hazardous conditions to the occupants of a building. In addition, the longer the structure remains exposed during restoration the more likely water damage can occur to the interior of the building. COREFLEX® has unique performance and installation characteristics that help reduce these problems. By utilizing proven waterproofing technology, COREFLEX can decrease exposure, demolition, waste and related hazards—saving time, cost and disruption.

PlazaDeck

Backed by the industry-leading quality assurance program.

Nothing threatens the structural integrity and interior environment of a building like water ingress. And the The HydroShield™ Quality Assurance Program is a proven systematic approach resulting in the most comprehensive water protection in the industry. Period.
