Expansion joints Principle The TENSA®COMPRESS A dilatation profile is a compression profile designed to compensate for expansion movements of up to 65mm and to seal joints and gaps. The TENSA®COMPRESS A dilatation profile is secured by adhesive and prestressed to absorb longitudinal, lateral and vertical movements in the building's structure. The specially shaped internal ribs ensure longterm stability in all profile positions. The TENSA®COMPRESS A dilatation profile is also resistant to road salt, fuels, lubricants, UV radiation and ozone. Application areas To absorb movements and seal joints...

Expansion joints Variations Joints without special edge structure If no mechanical loads at the joint edges are anticipated, the TENSA®COMPRESS A dilatation profiles can be installed directly after the joint has been suitably prepared. The joint flanks must be parallel and milled out to the correct depth; they must not have any cracks, broken-away areas or uneven surfaces. If the work is carried out carefully, the joints can also be formed with planed timber or smooth plastic strips. The conicity or slope of the joint flanks towards the outside must not exceed 3°, and the butt-jointed areas must be...

Expansion joints Instructions for installation & tender texts Preparing the joint gap Pre-formed or milled-out joints without special edge profiles must be inspected for cracks, uneven surfaces or broken-away areas. These must be rectified before installing the seal. The concrete must have dried sufficiently before the joint gaps are milled out to the prescribed width and depth. It is especially important for the joint flanks to be cleaned (e.g. by sanding or sand-blasting), after which the joint should be blown clean with a compressed air jet to make sure that all dirt is removed. When installing...
