Organic Swimming Pool Wall Cap Ideas

Greetings ~ we are searching for ideas to cap the wall in a natural swimming pool ala David Butler. He used some reclaimed oak wood. We do find some reclaimed wood beams on Craigslist. My question for this forum is if anyone has used anything else for the wall cap in an organic swimming pool?

Thank you!

Actually Scott, other than stone...wood below water level is probably the very best, and actually something I like better than stone in many applications because of its texture and feel over time. It takes on a smoothness and softness in texture that stone never can. Wood also seems to be less prone to cause injury to swimmers as it has soft rounded edges, is not as hard if fallen on, or as abrasive as stone is to sit on or brush against regularly..

I have seen gravel filled tires used to good effect also...These have almost as many creative application in this case as wood does, but I think wood is probably my first choice even over stone for much of this in regards to a "cost effective" natural pool. In theory (if not application) you could frame an entire area to for a solid wood pool....Fresh cut green "Chestnut" or "White" oak would probably work as well, if not better than old reclaimed wood that may have iron in it. Any species can be employed, but may need to be weighted down at first or attached in some fashion to the bottom.

Reclaimed concrete is often recommended but I can't agree with that as it can adversely affect the ph of the water, and/or release other toxins that may have been used in the material.
