Completed in May 2022, the underground utility tunnel on the University of Wisconsin campus in Madison, Wisconsin included the repair and expansion of the water and sewer lines between Lathrop Hall and North Hall. PENETRON ADMIX SB, a crystalline waterproofing admixture, was specified for the concrete steam tunnel and utility tunnel linings.
The University of Wisconsin is a public university and recognized research institute in Madison, Wisconsin. The 933-acre (378 ha) campus, located on the shores of Lake Mendota, is the flagship campus of the University of Wisconsin System. Lathrop Hall was originally built for the Department of Physical Training for Women in 1910 and was added to the National Register of Historic Places in 1985. Today, it is part of the School of Education and home to the University's Dance Program. North Hall was the first structure built on the University campus in 1851; it currently houses the Political Science faculty.
Extensive Repairs and New Construction
A $32.7 million project, the repair and expansion of the underground utility tunnel connecting Lathrop Hall with North Hall on the Madison campus was completed in three stages by Terra Engineering & Construction.
Site work included upgrading the underground utility tunnel between Lathrop Hall and North Hall with a bored, walkable concrete steam tunnel (approximately 630 feet long), a second, cast-in-place walkable steam tunnel (approximately 125 feet), steam box conduits (approximately 400 feet), chilled water supply and return lines (approximately 700 feet each), signal and primary duct banks (approximately 825 feet), water lines (approximately 1,000 feet), and sewer lines (approximately 700 feet).
“Wingra Redi-Mix, the ready-mix concrete supplier, was tasked by the project engineers to provide a durable waterproofing treatment for the underground concrete structures,” says Christopher Chen, Director of The Penetron Group. “They contacted Penetron for an optimal solution.”
Choosing the Optimal Solution
PENETRON ADMIX SB, delivered in soluble bags to eliminate measuring and simplify mixing, was specified for the underground concrete steam tunnels and utility tunnel. When added to the concrete mix, the active ingredients in PENETRON ADMIX SB react in a catalytic reaction with moisture in fresh concrete to generate a non-soluble crystalline formation throughout the pores and capillary tracts of the concrete. This formation permanently seals microcracks, pores and capillaries against the penetration of water or liquids from any direction, making the concrete impermeable.
