SETAUKET, N.Y., July 16,
2024 /PRNewswire-PRWeb/ -- The 2nd stage of
construction of the NINE by Mirvac residential development in
Willoughby (NSW), Australia,
comprising 214 units, was completed in June
2024. PENETRON ADMIX, a crystalline waterproofing admixture,
was specified to protect key below-grade concrete structures from
the high hydrostatic pressure of the region's groundwater
levels.
The insoluble crystals generated by
PENETRON ADMIX significantly increase the durability and extends
the service life of concrete and also helps minimize the need for
future concrete repairs of the below-grade structures at NINE by
Mirvac.
Willoughby is an upscale suburb situated in the Lower North
Shore (NSW), only 5 miles (8 km) north of downtown Sydney, Australia. Predominantly a residential
area and home to around 78,000 inhabitants, the city also features
substantial industries, commercial areas, and parks.
The new AUD$785 million (US$ 510
million) NINE by Mirvac residential development occupies the
8-acre (3.2-hectare) site of the former Channel Nine television
studios, a historic institution that broadcast stories of
Sydney, Australia, and the world
for more than 60 years.
The newly completed 2nd stage of construction comprises 214
apartments housed in five buildings, each 4-9 floors tall, as well
as a community pavilion open to the public. Once all construction
phases are completed by the end of 2025, NINE by Mirvac will offer
a total of 442 residential units of one-, two- and three-bedroom
apartments and penthouses (layouts of 58-126 m2 / 538-1,390 ft2)
housed in 10 buildings. The project also includes a 1,000 m2
(11,000 ft2) retail and commercial building, and a 6,500 m2 (71,500
ft2) landscaped public park with sheltered BBQ courts and a
children's playground, which incorporates recycled materials from
the landmark 233 m (770 ft) high
transmission tower (dismantled as part of the development).
"Due to the region's high groundwater levels and the almost two
dozen concrete elevator pits and stair well structures, ADG, the
project's engineering company, required a concrete waterproofing
solution that would optimize the durability of these structures,"
clarifies Steve Hodkinson, General
Manager of Penetron Australia.
PENETRON ADMIX, a crystalline waterproofing admixture, was
ultimately specified as the most reliable concrete waterproofing
solution. Holcim, the ready-mix concrete supplier, delivered
several hundred cubic meters of concrete to the various parts of
the construction site, which was placed by Azzurri Concrete.
Once mixed into the concrete, the proprietary chemicals in
PENETRON ADMIX react with moisture and concrete minerals to form
insoluble crystals throughout the concrete matrix. These crystals
reduce concrete permeability, provide corrosion mitigation, and
enable the concrete to self-heal (and seal) hairline cracks.
"The insoluble crystals generated by PENETRON ADMIX
significantly increase the durability and extends the service life
of concrete and also helps minimize the need for future concrete
repairs of the below-grade structures at NINE by Mirvac," concludes
Steve Hodkinson.
