Structural deck problems are often caused by moisture trapped between the decking and joists or beams, leading to wood rot and decay. Even pressure-treated lumber is known to rot where screws enter into the wood and create holes that collect water. Compromised structural integrity can lead to a risk of deck failure resulting in injury or death. Designing and constructing a waterproof deck structure is more important that any aesthetic product choice. Deck structures can easily be protected from water damage and rot by covering the joists and beams with Imus Cap or Imus Seal.

Imus Cap

Imus Cap is a patented, easy to install joist and beam cap designed to protect wooden deck structures from water damage and rot. Imus Cap is made of bonderized metal with a butyl rubber waterproof adhesive flashing that diverts water away from joists and beams and seals decking screws. Imus Seal is a self-adhering butyl joist and beam tape that provides the benefits of a joist cap at a lower price. Both Imus Cap and Imus Seal are compatible with common decking materials like naturally durable wood, pressure-treated timber, exotic tropical hardwood, thermally modified wood, and wood plastic composite.

If you are a homeowner, you want your deck to last. Structural deck issues are dangerous and costly to repair. If you are a professional, you want your deck designs or builds to be long-lasting and a good representation of your high-quality work. Waterproofing your deck joists and beams with Imus Cap and Imus Seal saves money by adding years of life to your deck structure.
