exisiting is a 1000 sq ft patio, ten-year old elastomeric which is at the end of its life, and a client who wants a dressed up surface. Living space below, and rightly so the integrity of the waterproofing is tops on her list. After considering tile and stone, I discounted them based on their weight, the potential I saw for damage to the roofing, the concealment and lack of access to the roof for repair, and lastly, cost.
A built up roof with sleepers/palletized decking atop was tossed because there is no room at the threshold. Anything I add to the surface will become a step up, on the way out. I do not wish to see a short step of three inches, my first impression is that it would look dumb, and the built up roofing will be creating a condition of the repellant exterior surface at a higher elevation than the interior, which I think dangerous.
So, I am left with elastomeric, which while functional and seemingly dependable, lacks charm. I think it looks good somewhere, just haven’t seen it yet. But I am going with it, with the possible addition of a flair.
I’m thinking about a process of renewing the existing, curing, and then laying ipe/teak similar in beds of elasto, perhaps of a color to accent the channels. The boards would be wet set into freshly rolled out elasto, then screwed every 6″ stagger into the existing 3/4 AC fir ply. 1×4, to reduce cupping.
This should greatly increase the life expectancy of the elastomeric(?), as it is totally protected from uv, traffic, and standing water. The concern now is the penetration of water into the channels, and how it might act on the elasto when stagnant. NW weather, very mild with little freezing, so that element of degradation is of little concern.
This will leave the following condition: old elasto over pro installed 3/4 ply, no water damage. refreshed elasto coating. third elastomeric layer is a bedding for the ipe planks, which are predrilled and screwed to the ply with 1 1/2#10 ss deck screws.
