Description
“At Eurolamp’s main facility in Thessaloniki, the primary water storage tank, although recently cast, showed substantial deterioration caused by an inadequate concrete mix,” notes Theodor Mentzikofakis, Managing Director and Partner of Penetron Hellas. “The company decided to undertake a comprehensive repair of the underground concrete structure to prevent further issues.”
Products Used
Surface preparation began with high-pressure hydro-blasting to clean the substrate and open up the tie-rod holes, honeycombed areas, and the construction joints between the floor slab, tank walls, and ceiling. PENETRON, a crystalline waterproofing material, was initially applied as a bonding slurry to the freshly prepared surfaces. PENECRETE MORTAR, a crystalline repair grout, was then used to repair and fill cracks and voids, followed by a final application of PENETRON across the interior surface of the underground tank, including the walls, floor, and ceiling. PENEBAR SW 45 RAPID TYPE A swellable waterstop strips were installed around the water pipe penetrations together with PENEBAR PRIMER, a bonding agent. PENETRON ADMIX, a crystalline waterproofing admixture, was also added to the concrete mix for recasting of the affected sections of concrete.
