Winston Hills Mall: Winston Hill NSW Australia
|
Xypex C-Series admixture & Kuniseal C-31DS waterstop were specified and used in the Winston Hills Mall upgrade carried out by SX Projects. Winston Hills Mall is a friendly and community minded centre with Big W, Woolworths, Coles and over 75 specialty shops and more than 1,100 undercover car parking spaces. The upgrade includes 140 additional car spaces, supermarket giant ALDI and upgrade of the external façade of the existing building to incorporate a new fresh look. Xypex C-Series admixture was specified by the architect (JKA Architects) as the waterproofing admixture for the exposed concrete roof deck, as it provides excellent cost benefits over traditional waterproofing methods, while also providing outstanding time savings for the builder over their very tight construction timeline. |

Due to the nature of the structure, the new concrete elements on the project are to be tied into existing concrete slabs on site. The structural engineer had called for each joining face of the existing concrete slab to be heavily scabbled to provide sufficient surface area for the adjoining new deck. As the surface is a scabbled surface, a number of waterstop products had to be considered for these cold joints. Kuniseal C-31DS waterstop was selected as the most suitable product for this application, as it is covered by a water soluble film, which will be dissolved in contact with water and which acts as an adhesive, and provides the flexibility required to align with the freshly scabbled surface. The Kuniseal waterstop is a swellable bentonite composition capable of swelling within the construction joint, providing a full waterproofing system. National Concrete Solutions (NCS) have been engaged as the main waterproofing contractor, as they have a full understanding of the Xypex product range, and have been trained in the application of all of the individually specified products. To date, approx. 400 Lineal meters of Kuniseal C-31DS has been installed. The main contractor is SX Projects, and is due for completion at the end of August 2011. |
