The 12" deck footer and 4" deck were simultaneously poured and I am concerned about the construction method used for the footer. Most of the footer was trenched below grade but due to the slope of my backyard, the far SE corner of the deck footer ended up being framed and poured on existing ground, above grade. Due to recent rainfall, I am already getting a little washout from UNDER the footer and I am afraid it will eventually completely washout. The footer will need to support a screen enclosure also. You can see by the pictures, the SE corner was not trenched by the lack of dirt in that area. Also, you can see it was framed and poured above grade by the lines the framing boards created and the grass on the existing ground.
Does this construction method meet code? Would you be concerned?
If this doesn't meet code, how would the pool builder correct this issue, the right way?
