Thanks to the newly created construction method, Aigner Albrecht were able to manufacture a maintenance-free system with mechanically highly precise contact surfaces machined conforming to standards for anti-slip pre-stressed joints.
Fittings that can be replaced as well as a central support profile being particular features.
Expansion paths 100 to 500 mm
XTEND road surface expansion joints with a collar finger construction expansion path of 100 to 500 mm. The system can be used in new constructions as well as in renovations.
Fittings conforming to standards ensure for an enormous load bearing capacity as well as an easy replacement without mechanical processing when required. The drain channel can be replaced from the top and bottom and can be pulled out from the side.
In order to be able to compensate irregularities under the steel sub-structure when filling with concrete, our expansion joints can be equipped with injection hoses. These guarantee tightness and correct support on the concrete.
