Floating Slab in Construction: What You Need to Know
What is a floating slab?
A. A foundation that is anchored into the ground
B. A foundation where the footing and slab are poured at the same time
C. A foundation constructed without any framework
D. A foundation built on unstable soil conditions
Answer:
B. A foundation where the footing and slab are poured at the same time
When the footing and slab are poured at the same time, it is indeed referred to as a floating slab. This method is often used in construction where the soil conditions are not ideal for a traditional foundation. The wooden framework that Beth referred to is used to mold the concrete into the desired shape. Once the concrete has hardened, the framework is removed, leaving the slab 'floating' above the ground rather than being anchored into it.
A floating slab is different from a standing wave, which is a concept from physics referring to the superposition of two identical waves propagating in the same direction.
