Joint and crack repair
Cut and Joint Technology

Maintain and rehabilitate traffic areas

POSSEHL SPEZIALBAU offers customized concepts for construction maintenance and new construction, from cutting joints to filling joints and cracks in asphalt and concrete surfaces according to ZTV Fug-StB, ZTV Beton-StB, ZTV Asphalt-StB and ZTV BEA-StB.

A wide range of cutting work is possible with our equipment. State-of-the-art hydraulic aggregates are used, some with integrated slurry suction devices. The execution of special cuts also presents no problems for our specialists. For the rehabilitation of cracks, we use the proven milling/casting method. By milling the cracks, the tension is removed and thus a longer durability of the rehabilitation is guaranteed.

  • Cutting of transverse joints, longitudinal dummy joints and press joints
  • notch cuts, diagonal cuts, extension cuts
  • Deep and separation cuts up to 50 cm cutting depth, diamond saw blades up to 1200 mm diameter
  • HGT cut-offs
  • horizontal cutting of curbs and bridge caps
  • cutting of concrete and asphalt for induction loops at traffic lights, docking systems on airfields as well as guided industrial trucks

  • Joint grouting in new concrete slabs
  • Repair grouting method
  • Crack covering method
  • Milling grouting process
  • HPS method ( hot compressed air system )
  • Execution of sealing strips

  • Filling of joints and cracks using cold grouting machines
  • Installation of one- and two-component joint sealants in concrete and asphalt surfaces
  • Sealing of filling stations, catchment areas or sumps in accordance with WHG (e.g. using permanently elastic polysulfide sealants)

  • Machine installation of prefabricated permanently elastic joint profiles in freeway and aircraft operating surfaces.
  • Used joint profiles are resistant to liquid substances such as fuels, hydraulic oils and de-icing agents
  • Installation also possible under weather conditions where conventional joint grouting is not possible

  • Installation of special joint profiles in various designs for traffic areas and industrial surfaces subject to heavy loads
  • Paving of asphalt pavement transitions (according to ZTV-ING)

  • Crack repair
  • Filling cracks in asphalt and concrete surfaces
  • Formation of seams, connections, joints
