Hollowcore Online

Hollowcore Online is a tool for calculating the dimension of a desired hollowcore in early stages of the design phase. The users can select a span, a load according to EuroCode amd then calculate. The application will suggest a supplier and give the user a profile that may fullfil the design criteria.


The results shown are calculated from the capacities given by hollowcore suppliers that participate on the website.

This tool is mostly aimed for architects, designers in early stages that want to use hollowcores in their precast concrete structures.

For more advanced calculations in later stages and to look for serviceability limit checks, PRE-Stress is recommended.
