Technical data sheet AQUAFIN®-CJ3 Suitable substrate Concrete Concrete system components after pre-testing
Preparing the substrate Requirement for substrate 1. Dry 2. Even 3. Clean 4. Free of adhesion inhibiting substances
Preparing the surface 1. The substrate may be matt damp. 2. Water puddling is not permissible.
Application Application 1. A concrete covering of > 8 cm should be carried out to the water-conducting side. 2. Glue AQUAFIN®-CJ3 with mounting adhesive for swellable waterstops. The concreting process can take place no sooner than 8 hours after adhesion. 3. Alternatively, AQUAFIN®-CJ3 can also be fastened with steel nails (min. 5 nails/m). When doing so, it must be ensured that it is pressed onto the substrate over the entire area. 4. Avoid looping and cavities. 5. Swelling tape connections can be applied with an overlap of at least 5 cm or butt-jointed. 6. Butt-jointed swelling tape connections must be secured with a separate swelling tape with an overlap of at least 3 cm.
Storage conditions Storage Cool, dry, protected from sunlight. Min. 5 years in the original canister.
Notes The swellable waterstop must be subjected to a visual check before concreting. Heavily pre-swollen joint sealing tapes are unsuitable and must be removed. A concrete covering of min. 8 cm must be complied with. Swellable waterstops must be protected against floating and slipping in all areas.
