SETAUKET, N.Y., July 24,
2024 /PRNewswire-PRWeb/ -- The first phase of
construction for the colossal One Thousand One mixed-use
development in Hawthorne
(Philadelphia), Pennsylvania (USA), was completed in
July 2024. PENETRON ADMIX SB, a
crystalline concrete waterproofing admixture, was chosen to provide
durable concrete swimming pool and deck structures, which are
constantly exposed to chlorinated water.
The Post Brothers team was happy with the
performance of the concrete mixes that were delivered for this
project.
A revitalized neighborhood in the South Philadelphia section of Philadelphia, Hawthorne features an increasingly youthful
demographic and many streets undergoing renovation of the historic
housing stock. The One Thousand One multi-use development in
Hawthorne spans an entire city
block at the intersection of South Broad Street and Washington
Avenue.
Designed by the BKV Group, a national engineering company, and
Nelson Worldwide, a national design and architecture firm, the
mid-rise residential / commercial development covers an area of
1,516,218 ft2 (137,840 m2). A series of "L" shaped 14-floor towers
bisect the site into four quadrants, providing space for 1,111
apartment units, a 15,000 ft2 office building, over 65,000 ft2 of
ground floor retail space, which includes a 40,000 ft2 Giant
Supermarket, and a parking garage.
"The first phase of construction comprised the completion of 600
apartments and 50,000 ft2 of commercial space," explains
Richard Farmer, Regional Sales
Manager for Penetron USA. "The
next phases, set for final completion by 2026, will further add 511
apartments and 15,000 ft2 of commercial space."
Post Brothers Construction, the general contractor, required a
robust waterproofing solution for the 3rd-floor swimming pool and
deck, which were poured using normal weight concrete. Elevated
concrete pool and deck designs, like the One Thousand One project,
have successfully utilized PENETRON ADMIX SB as a waterproofing
solution in many previous projects. Silvi Materials supplied the
concrete mix treated with PENETRON ADMIX SB, a permeability
reducing admixture, to waterproof the pool and deck concrete.
Post Brothers Construction collaborated with Penetron to explore
different waterproofing solutions, resulting in the adoption of a
unique strategy. Castor Materials, the ready-mix concrete supplier
responsible for the lightweight concrete segment, incorporated
PENETRON ADMIX SB into their mix design.
"This novel way of treating the elevated decks accelerated the
dry-in of the lightweight concrete and construction in various
critical areas. In turn, the upper elevated floors then provided
temporary waterproofing protection for the lower floors," adds
Richard Farmer. "By speeding up this
stage of the project, the new occupants were able to move in
earlier at Broad & Washington."
PENETRON ADMIX SB was mixed into 3,500 yds3 of concrete used for
the swimming pool and deck structures. Added to the concrete mix in
pre-measured soluble bags during the batching stage, PENETRON ADMIX
SB is formulated to react with moisture to produce an integral
crystalline formation throughout the concrete matrix. This makes
the concrete impermeable to water, liquids, and waterborne
elements, extending the service life of the concrete
structures.
"Thanks to tests carried out during the One Thousand One
project's early concrete pours, we were able to verify that
PENETRON ADMIX SB does not negatively impact the performance of the
mix or the process of pouring the lightweight and normal weight
concrete mixes," added Richard
Farmer. "The Post Brothers team was happy with the
performance of the concrete mixes that were delivered for this
project."
