Sealing of expansion joints
Expansion joints are special joints that are created in building structures to compensate for possible deformations that occur due to temperature changes, shrinkage, soil movement and other factors
Read articleThermoplastic tape for sealing expansion joints, cracks, joints
Teknomer thermoplastic tape for sealing expansion joints, cracks, in waterproofing basements, tunnels and other underground structures, pools and various hydraulic structures.
Teknomer thermoplastic tape has perforated edges, 250 mm wide and 1mm thick. It is a component of the sealing system with Teknobond 400 D epoxy adhesive.

The quality of the base / preliminary preparation
The application surface must be dry and free from any kind of dust, dirt, weak and loose particles, remains of cement mortar, oil and grease. If there are weak concrete parts, they should be removed, after which the surface should be repaired with a high-strength repair solution.
The concrete base must be clean, strong and have sufficient compressive strength (minimum 25 N/mm2) and tensile strength at least 1.5 N/mm2.
Stacking
Before laying the Teknomer tape, it must be cut with scissors or a utility knife according to the length of the compensation seam and wiped with a small amount of solvent.
If necessary, put the tape on top of each other, the length of the overlap should be 10 cm. The tapes are connected to each other with the help of hot air. If desired, a polyethylene wick larger than the expansion width is inserted into the joint.
The expansion tape is glued using special Teknobond 400 D epoxy glue, which is applied with a spatula 5 cm on each side of the tape. Do not apply epoxy to the middle of the tape.
In order for the tape not to lose its elastic properties quickly, it is recommended to lay it by making a straight or inverted omega. The next day, you should re-apply the material to the tape, paying attention to the high-quality finishing of the edges.
