From Realtà Mapei International n° 65 - 11/2/2017
The Wilshire Grand Center is a luxury, mixed-use skyscraper in the heart of Los Angeles. It has been constructed on the same site as the old hotel, which was demolished in 2012. Work on the skyscraper started on the 15th of February, 2014 with a 20-hour pour of 16,500 m3 of concrete to form the foundation for the structure.
With its ornamental spire, 73 floors (plus 5 more below ground level) and a maximum height of 335.3 metres, it is the tallest building in the city and in the whole of California. The skyscraper was completed this summer and now houses the 900-room InterContinental Los Angeles Downtown Hotel, more than 37,000 m2 of office space, various restaurants, shopping and commercial areas and a garage with 1,089 parking spaces on the lower floors.
Mapei played an important role in the installation of carpet flooring in the hotel. To ensure the work was carried out to perfection in compliance with eco-sustainable criteria, and that the flooring remains durable over the years, different products were used to prepare the surfaces and bond the floorings.
PREPARATION AND WATERPROOFING OF THE SURFACES
All the floors in the hotel were treated with ECO PRIM GRIP, a low odour, ready-to-use bonding promoter with very low emission of volatile organic compounds (VOC).
Once the surfaces had been treated, they were smoothed over and levelled with NOVOPLAN 2 PLUS, a self-levelling, rapid-hardening smoothing and levelling compound for new and existing substrates, to make them suitable for resilient and textile flooring in areas requiring good resis-
tance to loads and the levels of traffic typically found in offices and public areas.
MAPECEM QUICKPATCH ready-mixed, ready-to-use mortar, which is used to make controlled-shrinkage, rapid-setting and drying screeds, was used to repair the concrete surfaces, while PLANIPREP SC controlled-shrinkage, rapid-setting, fibre-reinforced cementitious mortar, was used as a final smoothing and levelling layer to guarantee the substrates were perfectly smooth and flat.
