Carriageway strengthening



Expansion joints


  • Applied along sides of any joint type

  • Prevents deformation of carriageway

  • Avoids wheel impacts on the joint

  • Protects joint and main structure

  • Reduces noise, increases comfort


The ROBO-STATIFLEX reinforcing beam is made of a special polymer concrete known under trade name ROBO-FLEX.
With a combination of high resistance to deformation and simultaneous elasticity, this reinforcing beam reliably prevents the formation of track grooves directly in front of and after expansion joint structures and their emerging from the road surface.


The installation of ROBO-STATIFLEX reinforcing beam is suitable for new and already existing joints. The prevention of the formation of track grooves increases the service life of expansion joints. Further advantages are an increased passing comfort of road users, the reduction of passing noise and a short total installation time.
