Therefore, formwork is utilized in regards to the shaping process utilizing a broad range of materials.
At the same time as selecting formwork, the sort of concrete and temperature of the pour are essential factors because they equally have an effect on pressure applied. The formwork parts should be capable of opposing the hydrostatic pressure of the wet concrete that would decrease to zero in few hours on the basis of setting and curing rate.

Subsequently, the overall rise is separated into an adequate assortment of risers. A flight of stairs must be straight and quite near to go up.
Features to consider:
- Maximum riser height must be 190 mm
- Tread depth begin at 255 mm
- One moving over and above two risers must be up to 585 mm to 625 mm
