The quality of the concrete surface is an important quality feature, especially for the inner surfaces of water tanks. A surface free of blow holes and with few pores hinders the growth of microorganisms and prolongs its lifetime.
Sheet piles are used as permanent or temporary support of excavations. Pecafil® formwork acts as a sacrificial back shutter for the concrete liner wall, the sheet piles are spanned and do not need to be filled with concrete.
Sorp 10® sound absorbers integrated into the concrete ceiling ensure good room acoustics and reduce reverberation time. In combination with Sorp acoustic plaster, a jointless, homogeneous ceiling design is achieved.
The requirements for shuttered fair-faced concrete surfaces are particularly high for representative structural elements in building construction. For this purpose, spacers with a minimum contact area are recommended in order to avoid marking the contact points.
