What’s underneath a finished deck?
Quite a bit, actually.
At our Mountain Cabin project in Snoqualmie Pass, this will eventually be a beautiful outdoor living space surrounded by the trees. The finished surface will be large-format pavers—but what Joshua is standing on here is part of what makes that finished deck work.
The deck has been waterproofed, and the pavers will sit above it on a pedestal system. Rather than trying to make the finished paver surface watertight, the open joints between the pavers allow rain and snowmelt to pass through to the waterproofed drainage plane underneath.
It’s one of those details most homeowners will never see once their home is finished.
But when you’re building a custom home in a mountain environment like Snoqualmie Pass, what happens underneath the finishes matters just as much as what you eventually see.
The best part?
When this is finished, the clients don’t need to stand out here thinking about waterproofing, drainage or pedestal systems.
They get to step outside and enjoy the view.
We’ll think about the rest.
Every Detail Matters.
