Base

The base must be undamaged and clean. Snow and ice must be melted away from the base. If necessary, also remove the weak-strength cement paste layer. Best adhesion can be achieved to a rough base. When using galvanised steels, you must make absolutely sure that the coating has become passive.

Mixing

Refer to the bag for how much water the concrete requires. Add the dry material to the water and mix with a concrete mixer for around ten minutes. With a power mixer, around one to three minutes of mixing is sufficient. Let the mass stand for a while and mix it again for a short while. Find the correct consistency at this stage by gradually adding the rest of the water. We do not recommend adding all of the water right at the start. If you are unable to use the concrete immediately after mixing, we recommend mixing it again before casting. The finished concrete remains workable for around half an hour.

Work instructions

Casting should be done as soon as possible after mixing. If necessary, vibrate the casting lightly or ram it. Recommended casting layer thickness 15-100 mm. Follow the instructions of the designers and the official regulations on winter concreting when doing casting work.

After treatment

The fresh casting must be protected from snow and rain. Strength development continues without additional heating in temperatures above -15°C.
