The structural slab usually is at the same level throughout except when required to have a drop in level due to drop in ffl or due to structural design.
Structural slab level vs structural floor level.
Screeding or concrete topping or mortar or substrate usually accommodates the difference between the structural slab and the floor finishes.
Ssl structural slab level.
Issues related to sloping of floors slabs varying the thickness of floors limits to sloping floors and the shortcoming of adding a slab edge to a sloped floor slab.
Ffl finished floor level.
Typically highways and parking lots along with most industrial warehouse and commercial floor slabs are designed with plain structural concrete.
And not being able to slope a variable thickness floor.
Although most floors slope it is important to know how much and why.
The ultimate goal is a flat level slab.
Ssl structural slab level is typically more used within the industrial and commercial markets and is very simply the level of which the structural concrete floor slab would finish however the term ssl is only use if there was to be other finishes to be placed over the structural slab.
The architectural floor the arch structural floor and the concrete slab.
Floor finishing level is the final reduced level of the flooring level tiles marble.
The steel provides.
Per say the floor finish level is 50 mm generally above the concrete mother slab level.
We know the steel will deflect under the weight of the wet concrete and because the slabs are often ul rated the design slab thickness is a minimum thickness to achieve the necessary fire resistance.
The average person can sense if a floor slopes 1 inch in 10 feet and sloping floors or sagging floors are often one of the warning signs that structural engineers look for when analyzing a house.
This video compares and contrasts the differences between 3 floor types.
Plain concrete slabs will be thicker than structural slabs yet in most cases cost effective compared to structural slabs.
