To serve the clients who visit Manufaktura commercial center in Łódź, the investor decided to construct an additional 12,000 m² large parking deck in the area. The main requirements of this project were high crack bridging ability even at low temperatures and a fast curing solution due to the unstable weather conditions in the area. The new structure of the bridge is designed to meet current seismic codes. More than 120 tons of Sikadur®-31 SBA were “smeared” to each side of each precast segment prior to final placement and tensioning. Over 200’000 bags of SikaGrout®-300 PT where supplied to fill the ducts containing the post-tensioned cables. Since several years Märker trusts the quality of SikaGrind®-870, a cement additive which is based on the Sika® ViscoCrete® technology. The integrated cement plant in Harburg and the grinding station in Lauffen produce all cement types which are relevant in the market. The product portfolio covers the complete application spectrum and Märker is able to provide cement in the market of South Germany. The Crayola Experience, which opened this past summer in Orlando, Florida, is a place where children can discover “the magic of color.” There are 25 interactive attractions and children are encouraged to play, explore, and learn. Sika supplied Sika ComfortFloor® PS-23 system in 2015 to this 30,577 square feet project.
