1. In road construction to seal edge joints and construction joints: Lasting sealing between poured concrete and/or roller-compacted asphalts and concrete pavements on roads and bridges. Lasting sealing of asphalt tracks with one another, e.g. hard shoulders to traffic lanes, for flawless repair seals and ruptured areas.
2. In civil engineering and channel construction: Sealing concrete pipes with round and oval profiles as well as sealing shaft rings and pre-cast concrete parts.

ESTOL-Joint Tape has plasto-elastic properties and good adhesive properties that mostly correspond to hot casting compounds for road and channel construction. ESTOL-Joint Tape is stable and packed true-to-form in order to enable convenient and easy handling at any occurring installation temperature, and it is resistant to traffic and weather influences. The bituminous basic mixture used corresponds to our joint and sleeve casting compounds in its stretching and adhesive properties, especially due to the addition of elastomers, as we have developed them based on decades of experience.

Primer K must be applied on a clean and dust free surface. The tape profiles are stuck on using Primer K. It is structured on the principle of a contact adhesive so that flawless adhesion is possible after the necessary full evaporation of the contained solvents. Before pressing on the tape it should be heated using a propane gas flame.

Adhesion to the already existing joint flank and the new asphalt layer and/or concrete part is done by fusing with the joint tape. Experience has shown that the temperature of the asphalt layer being installed is sufficient to heat a 10 mm tape continuously to +120 °C and thereby melt it flawlessly. Our tape is configured for this. The main difference between the installation of plasto-elastic joint tapes and joint sealing compounds is that the joint tape is laid before the bituminous layer is installed while conventional joint sealing compounds are applied afterwards.
Joint tape must therefore accommodate not only the seasonal temperature fluctuations against surface and edge adhesion, but also shrinkage when the asphalt layer cools. This should be taken into consideration when selecting objects for joint tape. We recommend only using joint tape where the asphalt layer being sealed has a force-locked connection with the substructure, in other words, where considerable horizontal movements cannot occur when the layer cools from the installation temperature to the normal outside temperature.
