Yes. The multidiameter clamp Abranyl® ABT allows the pipe to expand and contract freely. Due to our patented closing system the pipes are not secured with a screw and nut, and therefore can allow for movement. The ABT is also made from a modified nylon that is more flexible compared to materials such as PVC and also perform well against temperature changes.

Our ABT has also been KIWA certified for plastic water pipes, where they have been tested at +90°C

In this article we will explain to your what an ETA is, which tests our products have to undergo to obtain this certificate, why ETA approved fasteners are essential for safety-related applications, how long the service of life of ETA approved plugs and abchors is, plus much more!

The shelf lives of the composite mortars are printed in the catalogue and depend on the type of mortar. They are between 12 and 24 months.

Click to download the catalogue.

The best-before date is printed on each cartridge, calculated from the date of manufacture.

ResiFIX VY 300SF, for example, has a minimum shelf life of 18 months from the expiry date printed on the cartridge.

Even an opened and resealed cartridge of this mortar can be used for 18 months until the expiry date on the cartridge.

In most cases, the cartridge can also be used for a few months longer, but this is not 100% guaranteed. The decisive factor then is whether the two components that are in the cartridge can be mixed when they are squirted out and the material hardens well. You can try this out on a squeezed out test strand.

ResiFIX VYSF may be used for anchoring reinforcing bars / rebars and also has an approval for this application, as confirmed by the ETA (European Technical Assessment) Option 1 for cracked concrete.

The composite mortar ResiFIX VY SF also has an approval for subsequent reinforcement connection. But at present, it is not allowed to carry out a subsequent reinforcement connection with our ResiFIX VY SF injection mortar.

This sounds misleading, but the approval alone is not sufficient for the subsequent connection of reinforcement. The approval also requires that the craftsman must be trained to make a reinforcement connection precisely with our composite mortar. This training must - according to the legal situation - be carried out by us at CELO. At the moment, however, we do not offer such trainings.

If the craftsman nevertheless has the confidence to install the subsequent reinforcement connection (e.g. if he has done the training with another chemical mortar), he can of course do so, but he will then be outside the approval because of the lack of training for our product ResiFIX VY SF.

When opening a new cartridge you should always discard the first 10cm due to the two components not being perfectly mixed. You should start using the product when the colour is homogenous and dark grey.

After first use you should leave the mixing nozzle on the cartridge or remove the mixing nozzle and put the cap on the cartridge again. The cartridge can still be used until the expiry date (like an unused cartridge). 

If you still have any queries then please get in touch with us and we will be more than happy to assist you.
