Building an EPIC DECK — Part 3 Decking and Waterproofing

Building an EPIC DECK — Part 3 Decking and Waterproofing

For part 3 of my epic deck-building series, I dive into my waterproofing system. But as I continue to lay down my decking, I come across the consequences of my own poor planning. 

In this video, I used to TREX rain escape system and the TREX Transcend® series decking in spiced rum. The TREX decking was super easy to work with, fastened down well, provided the perfect gap built into its clips, and required no pre-drilling or plugs. 

So follow me as I take on part 3 of my deck-building series! If you’re following along at home or want to try it out for yourself, be sure to take a look at my video below.

DESTROYING My Backyard - EPIC Deck Series Part 3

waterproofing deck

First off, I start with the blocking. For this, I ripped some strips that are basically 2x4’s. These blocks give the railings on my deck something to screw into. I also flat block my deck to give me somewhere to screw my picture-framed edge in. This is key for the rain escape and as well as mounting anything else on the edges. 

Next up, I did some waterproofing. During this part, I installed the troughs from the TREX rain escape system so I could divert all of the water from underneath the deck to give me some dry storage. Then, I began to build the top of the deck. This part didn’t continue without its bumps and mistakes, but we pushed through it. 

For the Trex RainEscape system, there are a couple of ways to install the system on a deck that is longer than 19 feet.  The preferred way is to install two systems and have the water drain to both sides of the deck making for an easier install and doesn’t over load the gutter line.  The other way is to run one long trough and add a cantilever from the back side (maximum 4').
