Bitac is a high strength tape used in concrete and asphalt road pavements. It is used to control crack reflection as well as provide 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 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 has high strength and high elongation properties to ensure the waterproofing function and stress relief performance is maintained under the expected traffic loads.
Bitac acts as a waterproofing, stress-relieving membrane between the old road surface and the new seal, providing a long-term solution for road, bridge and culvert joints and repairs.
Asphalt Reinforcement for Ageing Pavements
Bitac geotextile strips are used to patch localised pavement cracks before the new surface seal is applied. Bitac acts as a waterproofing, stress-relieving membrane between the old road surface and the new seal, providing a long-term solution for ageing road surfaces. The strips are available in compact rolls allowing for fast, easy application by hand.
The loss of fill material between the joints of the culvert units leads to settlement of surface materials above the joint. Bitac provides a flexible barrier to prevent the movement of fine material through the joints, thus stabilising the entire structure.
Bitac multi-laminate tape provides an effective long-term waterproofing function for construction joints on new and existing concrete bridge decks.
- Bitac is self-adhesive and can be applied quickly and easily by hand.
- Bitac is quality guaranteed and will not shrink at high temperatures.
- It is simple to install, has proven performance over many years and is a cost-effective solution.
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.
