Project description

The REDI shopping center is currently being built with direct access to the underground. It will open in 2018 and is considered the largest shopping center in Helsinki’s city center.

Solution

The planar slab constructions rest on Calenberg Civalit® slide bearings. The deformations that occur are absorbed during setting of the concrete with low friction and the loads applied centrically to the adjacent components. Calenberg Ciparall® slide bearings are used in the area of point bearings. The low friction values allow an intricate, cost-effective construction.

Parking garage with an area of 50,000 m² (538,195.52 sq ft) and 2000 parking spaces. High loads and large rotations are the challenge in this project.

Solution

The loads and large rotations are absorbed by the Calenberg Compact Bearing CR 2000. The displacements occurring on the floating bearing are transferred according to plan by Calenberg Perforated™ slide bearings. The low friction value of a maximum of 2.3% allows an intricate execution of the prefabricated construction.

Project description

To protect against vibrations and structure-borne noise from suburban rail and tram traffic, it was necessary to provide various residential buildings near the Nordbahnhof with elastic building bearings.

Solution

The elastic bearings were made by designing point- and strip-shaped Cipremont® and Cibatur® structural supports. These elements were placed between the base and foundation slabs of the buildings. The vertical decoupling of the building areas near the traffic was carried out by Civerso. Ciflamon and Cidista were used as filling and covering materials for the elastic bearing joints.

Project description

On the approximately 150 m (492,14 ft) long property in Ezmattenweg in Bad Krozingen, in the immediate vicinity of the Hamburg-Basel railway line, 17 detached houses are being built. Measurements on site showed that a two-layer, strip-shaped laying of the Cibatur mats is required to achieve the high protection goals.

Solution

Because of the low load, full-surface installation could be dispensed with. Underneath the foundations, Cibatur® was laid in 2-ply 50 cm (19.69") -wide strips to ensure a high level of isolation. Vertical decoupling was done with Civerso.

On May 23, 2017, the Welfengarten foundation stone ceremony took place in Munich. Privately financed and subsidized rental housing units covering 18,900 m² (203,437.90 sq ft) are being built on the former brewery site. The Munich-Rosenheim railway line runs right next to the building. On-site measurements led to the conclusion that the buildings facing the railway line had to be protected against vibrations.

Solution

Installing elastic support under the floor slab with the Calenberg Cibatur mat effectively removed this problem.
