LockDry? aluminum waterproof decking is a maintenance free deck product that creates a waterproof area under the deck. LockDry? is ideally used for roof decks, 2nd story decks and replacements to underdeck ceilings and composite decking.
My company specializes in repairing and waterproofing failed balconies, stairs, and roof decks, so I see on a near-daily basis the results of water intrusion into wood framing, especially in mass-produced housing.
