Joint and crack sealing

Asphalt crack sealing

At the right time and the right location, the sealing of cracks on asphalt roadways is a proven preventive maintenance method.

This method allows to slow down degradation and delay the need for asphalt replacement. We offer both types of crack repairs, i.e. with or without cutting.

Since 1984, Groupe Lefebvre execute such works on the following:

  • MTQ’s highways and side roads
  • Municipal roads
  • Airport runways and tarmacs
  • Commercial parking garages

  • Hot (bituminous) sealant
  • Polyurethane or silicone base sealant
  • Polyurea base sealant
