Tampa Residences Expand Urban Lifestyle – Built on Penetron Technology

USA

The first apartment occupants were welcomed to the Altís Grand Central in August 2019. The mixed-use development, with original walls dating from 1891, specified PENETRON ADMIX to ensure a waterproof – and durable – below-grade structure.

The Altman Companies, a national rental apartment developer, and Mattoni Group, a Florida real estate investment firm, have completed the first apartments of the Altís Grand Central, a pedestrian-friendly residential development in the center of Tampa’s Riverfront district. Nestled along the Hillsborough River, the Riverfront neighborhood encompasses the University of Tampa campus, the Tampa General Hospital, a popular neighborhood of sophisticated dining and entertainment, and the bike-friendly Riverwalk shopping district.

“As part of the Riverfront district’s walkable environment, the Altis Grand Central complex offers shopping and dining alternatives on the ground floor,” adds Christopher Chen, Director of The Penetron Group. “In addition, the development is right across the street from the popular Oxford Exchange, with a restaurant, bookstore, coffeehouse and gift shop. And just up the street is the University of Tampa campus. It’s a very vibrant neighborhood.”
 

Rental Apartments in a Vibrant Community

The eight-story residential complex of Altis Grand Central offers 314 rental units, available as studio, 1, 2 or 3-bedroom apartments with floor plans ranging from 625-1,380 square feet (60-125 m2). The ground floor houses food and specialty shops, with the Commerce Club, a shared-work environment, and more office space above. Amenities include a Starbucks lounge and Internet Café, conference room and business center, bike garage, fitness spa, media screening room, spa with sauna and steam room, dog park, gaming room, bowling lounge, and rooftop pool and lounge.

“Apartment residents enjoy panoramic views of downtown Tampa and Tampa Bay from the upper floors and the rooftop sky lounge and pool,” adds Christopher Chen. “There’s even a charging station for electric vehicles.”

Located adjacent to the Hillsborough River that runs through the center of downtown Tampa, the Altís Grand Central development was faced with the challenges typical for a construction site on the Florida coast: high groundwater and the threat of chloride penetration into the foundation from seawater. Titan Concrete, the ready-mix supplier for the project, worked with the local Penetron specialist for an effective concrete mix to counter the environmental obstacles. PENETRON ADMIX, a crystalline admixture added to the concrete mix during batching, was specified for the numerous elevator pits.
 

Making Concrete Less Permeable

PENETRON ADMIX reacts in a catalytic reaction with moisture in fresh concrete to generate a non-soluble crystalline formation throughout the pores and capillary tracts normally found in concrete. This formation permanently self-heals and seals microcracks, pores and capillaries against the penetration of water, substantially reducing the permeability of usually porous concrete. As an integral waterproofing solution, PENETRON ADMIX provides low permeability, low shrinkage and self-healing properties, a highly effective combination for concrete structures in the high groundwater environments encountered in Florida.

“PENETRON ADMIX provided additional benefits such as increased compressive strength of the concrete and greatly increased resistance to chloride ion penetration from nearby seawater,” adds Christopher Chen.
