®T O T A L C O N C R E T E P R O T E C T I O NMSZ EN 12390-8:2009 (DIN 1048)Samples treated with PENETRON ADMIX ® (marked with a P) and two control samples are shown. All sampleswere exposed to a head pressure of 72.5 psi for 72 hours. This photo was taken immediately after splitting thesamples in half to measure the depth of water penetration. The PENETRON ADMIX ® samples exhibited a 94.4%reduction in water penetration compared to the control samples.Recent PENETRON PRAH ProjectsPENETRON’s permeability reducing technology has been proven in demanding high hydrostatic conditions in thefield with the highest success. Several recent projects highlight the effectiveness of PENETRON permeabilityreducingadmixtures in high hydrostatic service conditions: South Cobb Tunnel Lift Station near Atlanta, GA Tower Street Reservoir – an eight-million gallon water holding tank in Harrisonburg, VA National Road Bikeway Tunnel near St. Clairsville, OH Singapore Airport / Terminal 3, Singapore Gardens by the Bay, Marina Bay, Singapore Corredor Duarte, Santo Domingo, Dominican Republic Chennai International Airport, India4
®T O T A L C O N C R E T E P R O T E C T I O NSouth Cobb Tunnel Lift StationThis structure is a 212-feet deep shaft thatlifts sewage from over 32,000 LF oftunnels in Cobb County, GA. At theseextraordinary depths, the design – a wetwell within a dry well – required that thepermeability of the concrete be extremelylow to eliminate all concerns with leakingsewage from the wet well to the dry well(which is used by maintenance personnel).The ground water pressure at 212-feetelevations and the broken and shatteredpieces of inconsistent bedrock were majorwaterproofing concerns. PENETRONADMIX ® was specified as the PRAH forthis project; over 20,000 cubic yards weretreated and successfully waterproofed.Tower Street ReservoirLocated in Harrisonburg, VA, thisnew eight-million gallon concretewater holding tank replaced aleaking in-ground concrete-linedreservoir. Built by the CromCorporation, the new tankfeatures the permeabilityreducingbenefits ofPENETRON’s integral crystallinewaterproofing technology. Constructionof the new tank incorporateda PENETRON ADMI X ®Enhanced Shotcrete (PAES)application to protect thereinforcing steel embedded inthe concrete shell and to eliminateall leakage from the over70-feet high structure. PE-NETRON ADMI X ®’s ability toreduce concrete permeabilityunder high hydrostatic conditionsimproved Harrisonburg’s waterdistribution system by eliminatingwater leakage.5
