Single elementUsed in building, pedestrian and vehicular structures to seal the gap between two structures so that they can move independently without adversely affecting each other. The joints are of either aluminium or steel with a flexible seal spanning between them and can accommodate movement ranges between 15mm to 40mm.
Multi element Used in highway and bridge structures with large movements due to the effects of concrete shrinkage, thermal and seismic effects or differential settlement and ground movements. Typical movement ranges from 65mm per single seal upto 1m when connected together. VSL services include design, supply, 1st installation and long term maintenance.
Elastomeric expansion joints Elastomeric expansion joints have been designed to work as a single element, to be absolutely tight and long-lasting. These joints allow horizontal, vertical and oblique movements, remaining tight.
The elastomeric material properties are such that the bearings are not affected by low temperatures. Capability of impact absorption is kept during winter. The characteristics of this material also allows resistance to wearing and abrasion and resistance against bad weather conditions, chemical products and fire. Typical movement ranges from 40mm up to 330mm.
