Calculate what you need for your concrete floor!

Notice! The calculated recommended requirement is estimated on general basis and shall be seen as a recommendation only. For more accurate calculation, please, ask your nearest CombiForm representative or send an e-mail to info@combiform.com.

Type the total length of the slab/bedding
Only values from 1-4000 allowed.
Type the total width of the slab/bedding
Only values from 1-1000 allowed.
Decide how wide the bays/sections will be divided throughout the casting. Depends on concrete quality, temperature and vibration equipment.
Only values from 1-50 allowed.
The selected profile height of CombiForm depends on the total depth of the slab and the minimum space required between ground/gravel and the rail as the Screed rail needs to be filled with concrete. The distance between the rail and the ground should be a minimum of 1.5 x the largest aggregate. Never use an aggregate larger than 25% of the total slab depth.
Only values from 1-400 allowed.
Own means pre-fabricated concrete walls, wooden frames etc. No own frame arrangement, CombiForm profile will be used as a formwork and included in the recommendation.

Screed rail
This option considers the need of supporting ground plates. In almost every bedding it’s recommended to have supporting ground plates. An example of definition of stable ground is when slab is done on rough pre-done ground slab.
