Substrate quality / pre-treatment
The application surface must be dry and free from dust, dirt, loose and loose particles, cement mortar residues, oil and grease. If there are weak concrete parts on the surface, they should be removed and the surface repaired with Teknogrout or Teknorep repair mortars.
The concrete base must be strong and have sufficient compressive strength (minimum 25 N/mm²) and a peel strength of at least 1.5 N/mm².
Mixing components
Component B should be added to component A and mixed with a low speed electric mixer (350 - 400 rpm) for 2-3 minutes until a homogeneous working mixture is obtained.
Application
For gluing Teknomer thermoplastic tape:
The finished mixture is applied with a spatula to the surface on each side of the tape to a width of at least 5 cm.
Do not apply glue to the middle of the tape.
After gluing the tape to the base, the mixture is applied to the edges of the outer side of the tape to a width of 5 cm with overlapping edges.
To avoid loss of elasticity of the tape, it is recommended to lay it not tightly, but with a margin of sagging along the seam.
For anchoring reinforcing bars:
The diameter of the anchoring holes must be 4 mm larger than the diameter of the reinforcing bars. The mixture is laid in the hole at 2/3 of the depth. The reinforcing rod is also lubricated with the material before installation and is inserted into the hole with rotation until it stops.
To fill the expansion joint between foundations, special sealants or tape materials are usually used, which provide flexibility and the ability to compensate for deformations and movements between adjacent foundations

Expansion joints in concrete can be sealed with a variety of materials depending on project requirements and the type of joint.

Expansion joints are planned gaps in a structure that allow control of deformations caused by thermal or mechanical stresses, and also reduce the likelihood of cracks and damage in concrete or stone.
