The Greco-Roman Museum’s extended renovation and restoration, which began in 2005, included the construction and repair of numerous concrete structures. Before work could begin, the Museum’s 2,800 m2 basement garage (including foundation slab and retaining walls), the museum water tank (capacity: 84 m3/ 22,200 gallons), and the garage roof required a reliable concrete waterproofing solution due to the high groundwater encountered at the construction site and proximity of he Mediterranean Ocean.
To treat the new concrete parking garage decks, PENETRON ADMIX, a crystalline waterproofing admixture, was specified by the structural engineer to treat the concrete used for the foundation slab, retaining walls, and roof – for protection from high groundwater levels and pollution from a nearby wastewater treatment plant. The flagstones that lay on the garage roof, protected from the elements with an application of PENEGUARD, now form the museum’s new courtyard. PENEBAR SW 45 swellable waterstop strips were installed to seal the construction joints.
