Special designs & accessories

MAURER can offer special designs, e.g. for maintenance, the solution with MAURER Betoflex® or special accessories for a longer service life.

MAURER Betoflex®

MAURER Betoflex® is a high-quality, cold-processable polymer concrete for anchoring expansion joints. Particularly when repairing and replacing expansion joints, anchoring with Betoflex® can significantly reduce the construction time and cost. It is generally sufficient to create a recess depth corresponding to the pavement structure.

Designs: D1-B, XC1-B, XL1-B, K30-B, K50-B, transition area and supporting ribs

  • Reliable anchoring
  • Low overall height
  • No additional reinforcement or composite anchors required
  • No cracking in anchoring area
  • Watertightness
XC1-B
Supporting ribs
Transition area modular joint

Extremely improved corrosion protection – hybrid profiles

  • Standard-tested hybrid profiles including a stainless steel holding claw
  • Special corrosion protection in salty atmospheres
  • Lower maintenance costs
  • Improved sustainability

Improved sealing - Curved low point

  • No water in sealing profile area
  • Integrated flushing opening possible at the lowest point
  • Lower maintenance costs
  • Improved sustainability

Prevention of standing water – flushing opening in expansion joint

To prevent standing water on the carriageway, a flushing opening can be installed at the lowest point of the expansion joint.

  • Increased road safety in wet weather
  • Water is efficiently removed
  • Water can be routed directly to general bridge drainage system
  • Lower maintenance costs
  • Improved sustainability

Noise protection system below expansion joint - GU

Encapsulating the underside of the expansion joint reduces the sound waves radiated downwards in the abutment area, which could otherwise propagate over a very long distance.

  • Reduction of noise intensity by more than 50% (> 15 dB)
  • Sound absorption and sound reflection
  • Simple inspection and cleaning

MAURER Modular Bridging System (MMBS)

Due to the necessary lane closures, maintenance work  on existing expansion joint systems can often only be carried out at night. Therefore, a temporary safe covering of the expansion joint with the MMBS (MAURER Modular Bridging System) during the day is necessary. This can then be opened quickly and easily at night.

  • Use when replacing or retrofitting expansion joints
  • Controllable traffic management through temporary and section-specific use
  • Modular safe design
  • Preventing traffic congestion during rush hour phases.
