Bitac is a high strength tape used in concrete and asphalt road pavements. It is commonly used for controlling crack reflection as well as providing stress relief and waterproofing of joints. It can also be used to seal concrete joints found in bridge decks and precast concrete box culverts.

Bitac tape (also commonly called Bitac DS) consists of a self-adhesive geotextile that is impregnated with bitumen. This combination gives the product a rugged durability and high conformity to road surfaces. It combines high strength and high elongation properties to ensure the waterproofing function and stress relief performance is maintained under the expected traffic loads.

Bitac is supplied in roll widths of 166mm, 250mm and 500mm. All rolls are 20m long.

APPLICATIONS:

• Culverts

• Asphalt Reinforcement for Ageing Pavements

• Bridge decks

INSTALLATION:

All surfaces should be clean and dry before applying Bitac. A Bitac primer is applied to the surface and allowed to become touch dry before Bitac is unrolled, removing the release paper and then compressed to form the shape of the surface by rolling firmly into place to ensure a positive bond. The easy install process of Bitac makes it well suited for use for joints over service trenches, construction joints for concrete pavements, bridge deck joints and longitudinal cracks on existing surfaces.
