Is it common for stamped concrete to crack? Stamped concrete isn’t going to last forever. It will, eventually, start to crack and break down just like any other kind of concrete. However, stamped concrete is actually very resistant to cracking and, when you take steps to take care of it, it should hold up for a long time before it needs to be replaced.
How do you keep stamped concrete from cracking?

How reliable is a concrete rebound test?
The study further shows that the manufacturer’s rebound curve generally underestimates the actual compressive strength of concrete. Thus, conclusions as to the good condition and safe continued use of in-situ concrete based on the manufacturer’s rebound curve are conservative and can be fairly reliable.
What are concrete footings for patio?
Footings are an important part of foundation construction. They are typically made of concrete with rebar reinforcement that has been poured into an excavated trench.

What are the tiny hairs in concrete?
Fibers are usually used in concrete to control cracking due to plastic shrinkage and to drying shrinkage. They also reduce the permeability of concrete and thus reduce bleeding of water.
What happens if you place cured concrete in water?
Curing concrete with water prevents excessive loss of moisture as the water will create a layer for an extended period of time that can control the evaporation of moisture from the surface. After some time the concrete will start the chemical reaction that will eventually harden the concrete.
