Bluestone patio base question

Sir Topham Hatt · 2006-01-02T06:10:36+00:00

For my new addition, I am planning on installing a bluestone patio. To avoid a3 - 4 step drop to the patio from my family room, the GC wants to raise thepatio area. Now, I know that soil should be at least 6 inches away from anywood material (clapboard siding, sheathing, etc..) of a home, but my GC told mesince the material uses to raise the grade will be gravel and stone dust, so,there is no need to worry about covering properly flashed plywood sheathing withthis patio base material since it will not retain water. Is he shitting me orwhat?thxs

That's a dead cat space if there ever was one. I like the idea of the bridge, though - I'd just make it bigger so it would work into the design and you could landscape in the space.

Yes, if you use the short-gap method, you need to be able to take out the bridging material to clean out the gap. I'll admit I like the idea of a nice single-arch walking bridge to an "island" patio, though.

Are you suggesting that I use the same type of waterproofing I used on the foundation walls (brush on asphalt) and do I brush it on the sufaces covered by the patio base (pea gravel and stone dust) base will cover or just brush it on the joint between the foundation and sheathing.

In summary:

1) Brush on foundation waterproofing using embedded mesh 2) Flash the area with cooper or al. 3) apply a drainage plane

Also can you point me to a url of a drainage plane

The only thing I could find is something that is used for EIFS
