Decks
Cedar
"This deck has over 8" of airspace underneath with drains. The concrete border is actually a retaining curb wall." https://www.youtube.com/watch?v=XUKJXpuOruw&list=PL99BC4EE3ECE56A58&index=5
"Typically we use an asphaltic type of foundation water proofing along with drainage piping and drain rock."
"The concrete border is actually a deep curb creating an air space and room for drainage, footings, beams, etc." "We usually use redwood or Ipe' wood. Redwood is softer but will hold a stain longer. Ipe' is more scratch resistant but it is hard to get a sealer to penetrate, so people often have to stain every year."
