Besides termites, moisture is the worst enemy for a wooden deck. Moisture over time causes rot, mold, mildew, and headaches. How can you protect your wooden deck? Let’s look at how water affects wood first.
hygroscopic, meaning it gains or loses moisture as the relative humidity of the
air surrounding it changes (Loffer, 2018). There should be some moisture in
wood, but too much causes trouble.
water seeps into wood fibers, it is called fiber saturation. First the water
goes into cells, but once the cells are full, water will overflow into the cell
cavities and start the process of decaying (Canadian Wood Council, (2019). As
water fills the cell cavities, it causes the wood fibers to stretch creating a
weaker board, which can be unsafe (University of Cambridge, 2018).
potential solution is that you can use treated lumber and try to continue to
seal it every year. Every. Single. Year. Or use composite lumber, which would
help with moisture, but peeling, fading and sagging are known downfalls of
there is a permanent solution. Get a stone deck instead.

now with the StoneDeks System. The system allows any stone to be placed on and
elevated surface and allows for drainage and permeability.
Canada where moisture is a huge problem due to snow, a stone deck using the
StoneDeks System has stood the test of time for over ten years.
re-sealing. No more rot. No more headaches.
Just a nice, relaxing stone deck that is as equally beautiful as it is low maintenance. And your neighbors will be impressed at the sight.
