The Romans developed concrete. The Romans were not the first to use concrete, but they developed a new and better type of concrete by using pozzolana, a type of volcanic rock found at Pozzuoli, a suburb of Naples. Roman concrete was so good that it also set underwater and was used to build the docks of ports. Roman concrete was as strong as modern concrete, but was less fluid and could not be poured into moulds. It had to be layered by hand. The Romans also discovered that by adding horse hair, the concrete was less liable to crack while it set and that blood made it more frost resistant. The Romans also laid concrete in arches and vault to exploit the great load bearing capacity of these structures.
Basically they dug a trench, and then filled it with rock/stone/sand (Whatever was locally available) and then topped it off with larger stones and concrete. (Yes, The Romans used concrete, they probably discovered/invented it, but after the collapse of the Roman empire the method of making is was "lost" for 1,300 years!)
