What kind of wood can be submerged in water?
The granddaddy of all the moisture-resistant woods is certainly teak. Because of its natural oiliness, teak can withstand wet conditions very well.

What happens when treated wood gets wet?
The chemical preservatives present in the wood can't protect it from decay. That means pressure-treated wood can absorb moisture and rot over time.
Can treated wood be left in rain?
While the chemicals in pressure treated lumber prevent rot and ward off insects, they don't prevent moisture from seeping into the wood. On a deck that's going to be directly exposed to rain, water can seep into the boards and cause them to swell. As they dry in the sun, they'll shrink.

How do pressure treated poles work?
Pressure treated poles are driven into the ground along the length of the wall, and used alone or in combination with sheathing to create the final barrier. These structures help prevent erosion and keep the area in front of the barrier safe from falling debris. Working with Pressure Treated Lumber Safely.
Why do wood posts break off?
Poles and posts made of natural wood would quickly rot, or become infested with fungi or wood-boring insects, eventually causing the post or pole to break off at ground level. By using slightly higher concentrations of wood preservatives, pressure treated lumber can be used in situations where it is constantly in contact with the ground.

Why do I have gaps between deck boards?
Using deck boards, you could divert running water. One reason for gaps between deck boards is to allow rain to run off the deck instead of pooling. I would never recommend using untreated wood decking, but small amounts of rain will run off an untreated deck with only minimal absorption.

Trex.
