SynkoElast® profile rated-crack B= 100 mm

SynkoElast®

SynkoElast® can be laid both in fresh concrete (in-situ concrete) and on set concrete. For the latter, a primer is then required. During concrete curing, the concrete and SynkoElast® tape bond together so that water penetration is stopped. The joint created between the concreting steps is sealed securely and permanently by the SynkoElast®. The sealing tape is used for sealing structural components made of waterproof in-situ concrete and element walls, for example in basements and underground garages. The construction joint tape does not swell when it comes into contact with water, so it can be laid even in the rain. It is therefore also possible to join narrow components together without having to fear concrete spalling. SynkoElast® is so versatile that it can also be used in changing water levels and provides a permanent seal. SynkoElast® is generally approved by the building authorities up to a water pressure of 2 bar.

Advantages of the SynkoElast® joint tape

• Quick and easy installation
• Flexible use in fresh and hardened concrete
• Processing from 0°C to 35°C
• Up to 20 m water permanently tight (2 bar)
• General test certificate issued by the building authorities
• No swelling on contact with water
• Weather, acid, alkali and salt resistant

Technical information

SynkoElast® also seals concrete sections and can also be used as a subsequent sealant for construction joints. A SynkoElast® primer for use with hardened concrete is available as an accessory.

• Black color
• Consistency elastoplastic
• Processing form on rolls with protective foil
• Spec. density Approx. 1,3 g/cm3
• Adhesive tensile strength > 18 kPa (on concrete)
• Max. Joint displacement < 3 mm (for the size 30 x 20 mm)
• Temperature resistance -40°C bis +70°C
• Processing temperature 0°C to +35°C (component and material temperature, storage at room temperature facilitates processing at low temperatures)
• Chemical resistance H2SO4(pH 4)-acid, concrete attacking liquid Ca(OH)2(pH 12)-alkali NaCI salt

Applications and possible uses

SynkoElast® is used, among other things, for sealing joints in structures of water-impermeable cast-in-place.

• Working and nominal crack joints in cast-in-place concrete
• When concreting the floor slab in several sections
• Element wall joints in combination with predetermined crack profiles and stopend elements
• Connection to set concrete with cast-in-place
• Connection from floor slab to wall and for wall and ceiling connections

When used for general structural waterproofing and in accordance with the corresponding "WU Guideline", the General Test Certificate issued by the MPA Braunschweig (P-6101/9650 MPA BS) must also be observed.
