Development consisting of shopping and hotel

São Paulo / Brasil


Project Fixation of wooden louvers on the tower facade

Date: June 2019


With 145,000 m² of construction, the development comprises a shopping mall and a 6-star hotel with 122 suites, in addition to the restoration of an existing chapel on the site. The building is impressive for its size and stands out for including the preservation of a historical heritage, in addition to overcoming several challenges in the engineering area.

One of the highlights of this civil construction icon is the external cladding, which has wooden louvers and natural vegetation. The louvers system will be supported by the structure of the building, with the aid of threaded bars fixed to the concrete with the WQI 44 Chemical Anchor from Walsywa.

The fast-curing, high-strength vinyl ester-based resin was chosen because chemical anchors do not create stresses in the concrete, due to the way these products act. This feature is very valuable for fixing the louvers that make up the building’s facade, since they will be very close to the edges of the concrete.

In order to attest to the efficiency and safety of the product, tensile tests were carried out on the applied studs, and all were approved.
