Formwork systems

Your site team and our Doka specialists work closely together to select the right formwork system. Site requirements such as overall construction time, workflow (cycle time) and personnel resources are factors in deciding on the right formwork system.

Safety in every situation

For our customers we develop project-specific safety concepts to permit unimpeded operation, safe repositioning of the formwork and safe and fast access at any height. Safe, smooth work routines speed up the workflow.

Site infrastructure

Smooth and efficient construction progress depends on functioning site infrastructure. Well thought-out formwork solutions standardize and speed up repetitive jobs, reduce risk, allow for an ideal work environment and simplify the workflow.
