The use of the MAX FRANK controlled permanent formwork liner when concreting tunnel tubes enables an almost void-free, resistible concrete surface.
Water-bearing components e.g. containers and pipes for drinking water, sewage treatment plants or pressure pipes for power plants made of concrete require closed and resistible surfaces to avoid being damaged early.
Especially in horizontal pipes, it is very difficult to create a void-free surface at the bottom of the tube as bubbles accumulate on the formwork.
Through the targeted use of the MAX FRANK CPF liner (controlled permanent formwork), those problems can be solved.
The MAX FRANK CPF liner enables air pockets and excess water to be selectively diverted from the fresh concrete.
After stripping the formwork, the result is a virtually void-free, optimized concrete surface with high resistance against abrasion, hydrolysis and chemical attack.
