Repairing cracks in asphalt and concrete

Cracks in asphalt and concrete surfaces can occur due to various factors such as ageing, traffic loads, temperature fluctuations and ground movements. This can lead to water getting in, which can cause major structural problems if action is not taken in time. The type of crack repairs has to be adapted to the damage and the type of road surface.

SO CRACKS DON’T
BECOME A PROBLEM.

ADVANTAGES

The treatment of cracks prevents the penetration of surface water and solids

Subsequent damage caused by penetrating water, such as erosion of the support layer, reduced layer composite or frost fractures, is prevented

Processing of cracks in concrete surfaces, in combination with other repair work (e.g. stabilising concrete slabs, anchoring retrofit) in accordance with ZTV BEB-StB, considerably prolongs the concrete surface’s remaining useful life

Two repair options:

  • Crack covering method: surface sealing, very high daily output, low cost (asphalt)
  • Routing and sealing method: permanent sealing, movement absorption possible (asphalt and concrete)
