Areas of application
BORNIT® Crack Tape is used as sealing tape in asphalt road construction for sealing open seams and cracks with up to 3 mm in width. The tape flexibly bridges the seam or crack area, resp., and thus effectively prevents penetration of surface water. It can serve as substrate for asphalt mix application without any problem later on.
BORNIT® Crack Tape can be used wherever a fast and simple crack and seam repair method is required.
On motorways, the use of BORNIT® Crack Tape is not recommended.

Type and properties
BORNIT® Crack Tape is a flexible bitumen sealing tape for secure repairs of cracks and seams in the surface area of asphalted surfaces.
The product consists of polymer-modified bitumen and special fillers.

Advantages
  • very flexible
  • less equipment and labor required for processing

Surface
The seam/crack area must be dry and free from loose particles.

Processing
BORNIT® Hot Compound Primer Spray or BORNIT® Bitumen Primer Spray must be applied as primer on both sides of the area. The quantity of the primer depends on the absorbency of the substrate. Overdosing should be avoided. Following drying of the primer, BORNIT® Crack Tape is applied to the crack area with little pressure, the separating paper peeled off and the tape firmly pressed on to the substrate using a roller or hand stamper. In order to prevent sticking of the tape to the work equipment, crusher dust must be spread onto the surface.

Note: At temperatures below +10 °C, the adhesive strength of the tape can be increased by slightly warming the asphalt using a propane flame.

Important note
The causes for cracks in asphalt are normally stresses and forces caused by most different influencing factors (e.g. insufficient load-bearing capacity of the foundation, defects during asphalting, etc.). Following an object-dependent service life of the repaired areas, cracks may therefore occur again and thus make repeated treatment with BORNIT® Crack Tape necessary. Permanent repair of these damaged areas is only possible by eliminating the causes. A more durable repair of cracks is possible by proper milling out and subsequent filling with suitable hot sealing compounds (e.g. BORNIT® Hot Sealing TL).
