Rigid pedestal bearings
Pedestal bearings consist of a circular plastic disc on which a joint cross is attached. There are rigid and adjustable pedestal bearings, which can be used with different techniques and the height compensation. In the rigid variants usually a foot ring is available, can be plugged into the balancing rings. On the overhead ring is then usually fixed with plug-in technique, the joint cross on which the corners of the concrete slabs are placed.
Adjustable pedestal bearings St The pedestal bearings, which can be infinitely adjusted in height by means of a central thread, consist of a round foot section into which a round stud with external thread is screwed into the internal thread of the foot section. A screw-on ring with internal thread and cross-joint webs is screwed into the required height and can be adjusted to millimeter precision by any number of revolutions. A second variant are pedestals with four independently adjustable threaded connections. This allows each corner of the concrete slab to be adjusted individually.
Water drains through open joints
Plain solid surfaces, such as a screed or heavily compacted soil, may be used as support surfaces for pedestal storage. By placing the concrete slabs under the laying surface creates a cavity through which the water can drain, which penetrates through the open joints. The cavity height can be adjusted and increased depending on the construction project or expected rainfall. Theoretically, cavities of up to fifty centimeters are possible.

Depending on the intended height compensation, support and intermediate rings must be added to the basic prices of the individual pedestal bearing. Special finishing elements for the edges of the laying surface of the concrete slabs are to be taken into account as extra items, but single-threaded pedestals can not be used as finishing elements.|

- Tips & TricksThe drainage of water from regular drying of surfaces covered with concrete slabs is of particular concern to manufacturers. Especially for locations subject to heavy wear and tear due to moisture or strong weather, pedestal bearings with special drainage and drainage properties are developed. These products are referred to as draining pedestal bearings.
