Project Profiles
Philadelphia International Airport Parking Garages
The Philadelphia International Airport parking garages contain approximately
a total of 3.5 million square feet of IPANEX modified concrete. In 1976 IPANEX was
used to treat the decks in garages C and D. After 25 years of service, the concrete
topping is still in good condition.
In 1990 IPANEX was used once again in all topping concrete of two additional
Garages totaling 756,000 square feet. The success of IPANEX in the airport garages built in 1976 and 1990 prompted the use of IPANEX admixture once again in three
new garages: E, F, and 1 ( 1,500,000 sq. ft ), built in 2001 – 2002.

Pennsylvania Turnpike Bridges - 1973-1974
Eight turnpike bridges were replaced between Bedford and Somerset,
Pennsylvania. IPANEX admixture was used in the concrete deck of one of
the bridges. All the bridges are located within a 5 mile section with similar
exposure and traffic conditions, and received heavy applications of
deicing salts.
The concrete bridge deck incorporating IPANEX was evaluated by independent researchers
and found to be in good condition after 25 years of service life as of
1998. The facts presented in the report reveal that the IPANEX modified bridge
had superior performance and excellent resistance to corrosion of reinforcing
steel. The concrete in the control bridge decks have shown serious signs of
distress, including spalling, delamination and cracks.

Humana Inc. Headquarters Building - Louisville, Kentucky - 1983
This high-rise (580,000sq. ft.) office building contains a below grade two story
concrete garage that must resist up to 16 ft. (4.9 m) of hydrostatic pressure from
the nearby Ohio River. Buildings subjected to hydrostatic pressure must be
waterproofed to prevent the pressure from forcing water through the walls and
slabs. IPANEX admixture reduces both the volume of water entering the concrete
and the depth of water penetration into the concrete.
IPANEX admixture was successfully used in the concrete placed in the Humana
building structural mat, foundation walls, and a three story foundation and
waterfall.

University of Michigan Stadium - Ann Arbor, MI - 1972
In the spring of 1972 a program was started to rehabilitate the entire interior
concrete surface of the University of Michigan stadium. The risers and tread
surface were severely deteriorated or spalled in much of the 460,000 square feet
area circa 1972.
The method of repair was specified using an IPANEX Modified Repair System.
Between 1972 and 1979 contracts were let each summer. By 1979 the entire
interior rehabilitation project was completed.
Additional information can be found in the "Stadium Steps Repaired With Zero
Slump Mortar" article in Concrete International magazine, September 1980,
and in the stadium review summary completed in 2001. Click

Winchester Wastewater Treatment Plant - Winchester, Virginia
In order to contain wastewater, prevent groundwater from penetrating containment
tanks, and eliminate premature deterioration of concrete due to continual exposure
to a wet environment, waterproofing water and wastewater treatment plants is a top
priority. IPANEX admixture has been successfully used in water treatment facilities
for over 30 years.
IPANEX provides permanent waterproofing throughout these structures. The characteristics
of IPANEX concrete will not deteriorate over time, or require additional maintenance.
IPANEX admixture is an economical alternative to waterproof coatings. The installed
cost for a crystalline waterproof coating is typically higher than the added cost of
using IPANEX because there is no surface prep or labor costs associated with the use of
an admixture. IPANEX is NSF Standard 61 approved.

Harrah’s Casino Parking Garage - Atlantic City, NJ - 1980
Harrah’s Casino parking garage is precast with field topped double-tees.
IPANEX admixture was used in approximately 700,000 square feet of 2 ½ inch cast in
place concrete topping.
Harrah’s Casino in Atlantic City is located in a Zone III according to the
American Concrete Institute. This is the most severe environmental
zone where freezing and de-icing salts are common. Despite exposure to
the extremely severe salt water environment Harrah’s Casino parking garage
continues to perform well.
IPANEX admixture was used in several projects in the Atlantic City area
including the parking garages or structures of the Tropicana, Showboat, and
Claridge Casinos.

Camden Aquarium Penguin Exhibit - Camden, NJ - 1998
Wet-mix shotcrete is another method of concrete application in which
IPANEX has been proven successful. The shotcrete process eliminates
the use of membranes, creates compatible integral coloring and helps
prevent effloressence. A primary reason IPANEX is used in shotcrete
construction is to improve the concrete’s ability to resist hydrostatic
pressure.
