Expansion Joint Tape
Thermoplastic elastomer based EKAFLEX is a permanently elastic dilatation band used in joints of all types of construction and expansion joints. During application, high performance EKAFIX Epoxy Adhesive should be used.
- In underground applications – underneath the plants.
- In waterproofing of horizontal / vertical dilatations.
- In the insulation of wide and irregular cracks.
- In elastic waterproofing of base-parapet connections.
- In the joints of different building materials such as steel construction and reinforced concrete.
- In the swimming pool and wastewater units.
- It is used in tunnel and similar underground structures.
- UV resistant.
- High resistant to plant roots.
- Resistant to bacterial attacks and chemical degradation.
- High resistant to environmental influences and aggressive environments.
- Easily processable.
- High elasticity.
Method of Application
Surfaces must be clean, free from carriers and loose particles.
EKAFIX (Epoxy adhesive) has two components. Component A (3.75 kg) and Component B (1.25 kg) are mixed in a low-speed mixer until homogenous before mixing. With trowel and spatula, EKAFIX (Epoxy Adhesive) is applied to the dilatation sidewalls with a thickness of approximately 1.0 – 1.5 mm. The application width should be at least 40 mm for the 20 cm tape, and at least 50 mm for the tape 30 cm. To ensure strong adherence, the adhesive must be thoroughly applied.
The areas to be applied should be identified and the appropriate tape lengths should be prepared. The tapes to be added are prepared by boiling them with hot air gun before application. EKAFLEX tape is laid on the adhesive layer and with the help of a suitable roll, full contact is established between the tape and the adhesive layer. In the same way, EKAFIX Epoxy Adhesive is applied to the top surface of the band. The application is done with a thickness of 1.0 – 1.5 mm and a band of at least 20 mm, the layer is allowed to harden. EKAFIX Epoxy Adhesive tape should not be moved, lifted and must be protected against water and/or mechanically stressed until it is fully hardened. It is important to consider that, in cold weather the drying time of the adhesive is longer than it is in hot weather.
