If bearers are too low they may restrict water movement and over time soil will build-up, further hindering water movement.

Ventilation – Good air movement is required beneath a deck to prevent moisture from building up and damaging the deck sub-structure and fixtures.There are three main concerns with low level decks that might lead to your deck having a reduced lifespan.
