The South Cobb Tunnel Lift Station in Austell, Georgia, was the largest expansion project and deepest tunnel construction undertaken by the Cobb County Water Authority (CCWS), and it was completed a year ahead of schedule. Part of a comprehensive sewage and wastewater treatment system, the 5.5-mile-long tunnel was built through hard rock at a maximum depth of 400 feet. The project also included a 130 million gallon/day lift station to transport wastewater flows; the height of the station is about 212 feet. PENETRON ADMIX was used to ensure the concrete structures, tanks, foundation slaps and containment structures could resist the high levels of water pressure remain watertight. The admixture was also added to the concrete lining used to support areas of fractured rock and groundwater inflow.

To keep a live tiger mascot happy at Louisiana State University (LSU), you need a substantial water area (including a large pond and waterfall for hot weather), an enormous synthetic rock (with a heated or cooled surface, as a lookout for the tiger), and new landscaping. Construction of the upgraded habitat specified PENETRON ADMIX SB (in soluble bags) to provide an integrated crystalline waterproofing solution. Applied as a wet process shotcrete application, the PENETRON ADMIX SB was added to the PENETRON ADMIX-Enhanced Shotcrete (PAES) to create a durable and naturalistic surface for the lookout rock and provide a new, waterproof surface for the pond and waterfall area. Mike the Tiger attracts more than 100,000 visitors each year and can be viewed via the live webcam at www.MiketheTiger.com.

The expansion of the Canpotex Marine Terminal 5 in Portland, Oregon, enlarged the facility’s capacity to process and ship white potash to overseas markets. Initially, a membrane solution was specified to protect the concrete piers, tunnel and building foundations. However, the project owners opted for an integral solution, thanks, in part, to many contractors who said they saved time and reduced construction costs when switching from a traditional surface applied waterproofing to a Penetron crystalline solution for projects located in a marine environment. Penetron worked with Cal Portland to design an optimal concrete mix that met the demands of the marine environment. PENETRON ADMIX was used to waterproof all new concrete. PENETRON slurry and PENECRETE MORTAR were applied to the tie holes and to patch previous honeycombing and defects.

San Diego’s Metropolitan Transportation Service (MTS) new, high-efficiency wheel truing pit keeps MTS rail cars rolling smoothly. When the general contractor began construction, water quickly filled the construction site (almost three feet under the water table). To finish the excavation, seven dewatering pumps were installed to keep water out. The project was a small but complex mix of new and existing construction with numerous unique conditions, all requiring  a waterproofing solution Ultimately, Penetron crystalline products were chosen over traditional waterproofing solutions, including PENETRON ADMIX for the footings, slab and walls of the truing pit, PENEBAR SW waterstop strips to seal all cold joints, and PENECRETE MORTAR to patch any remaining cracks and imperfections in the new concrete structure. The choice saved construction time and money.

The expansion of the Oyster Creek propylene production facility in Freeport, Texas, was a key part of Dow Chemical’s multi-billion-dollar investment (Gulfstream) program to take advantage of low market prices for locally-produced shale gas. The massive scope of construction made easy application and reliability of the concrete treatment solution a priority. PENETRON ADMIX SB was specified as a robust waterproofing solution for all concrete used for the water containment tanks – each with a capacity of 1.5 million gallons (5.7 million liters). As an integral waterproofing protection, it prevents penetration of water and aggressive agents into the concrete and also features a self-healing capability. Delivered in pre-measured soluble bags, the admixture simplified accurate dosage during batching and saved time in the construction schedule.

Modera Coral Gables is a 237-unit luxury apartment mid-rise building in Miami, Florida, located on an urban infill area and only one block south of Coral Gables’ Miracle Mile, a pedestrian-friendly entertainment and retail hub. The building is LEED Silver-certified and has six residential floors above three levels of parking. A large pool is situated on an expansive elevated deck on the fourth floor. Originally, a bentonite mat was specified for the foundation. Because excavations were five feet below the water table, it became impossible to eliminate enough water to install the mat. Cemex, the ready-mix supplier, worked with Penetron on a solution. PENETRON ADMIX was mixed into the concrete for all below-grade structures (and also the three-level parking garage and the fourth floor pool structure), allowing placement of the concrete into the waterlogged site.
