Products Used

Looking for a concrete waterproofing solution for the Gelado, Pera Jusante, Jacaré, Kalunga, Estéril Sul, and further tailing dams, Penetron recommended the Penetron System of concrete waterproofing products to ensure the integrity of these dams. PENESEAL PRO, a spray-on liquid sealer, was applied to reduce the permeability of the concrete and seal hairline cracks. PATCHLINE PAVE, a repair mortar, was directly applied for specific repairs, and PENETRON CR-90, a fast-setting, crystalline waterproofing material, was used to restore the hydraulic surfaces of the concrete spillways.
