Concrete driveways are typically poured four inches thick, giving the concrete driveway enough strength to withstand loads of regular vehicles (up to approximately 8,000lbs).

How much weight does it take to crack concrete?

Concrete cracks caused by overloading the slab

Placing excessive amounts of weight on top of a concrete slab can cause cracking. When you hear a concrete mix has a strength of 2000, 3000, 4000, or 5000+ PSI, it is referring to the pounds per square inch it would take to crush that concrete slab.

How deep should a concrete slab be for a pool?

The thickness of the concrete and rebar depends on the environment because the pool has to be able to withstand the forces pushing against it (soil outside and water inside). To be structurally sound, a concrete pool shell should generally be 6 inches thick.

Heavy-duty wire mesh can offer the required level of durability while limiting your costs considerably.
