How is the wood Venice is built on not decomposing over time?

(Not sure about the flair.. sorry)
Wooden beams in earth (like with fences) rot over the years and break.
I was under the impression that this was because of water.
Shouldn’t Venice “sink” because of rotten beams?

Water preserve wood. At least water in swamps. As an example, oak poles that was yout in a swamp to mark borders totally vanishes above ground in 100 years. The part that is still below the surface of the swamp are as good as new.
