The previous owners of our house were big on bad DIY projects. I was crawling around under the deck today and I may have figured something out. They used to have a concrete patio, but decided they wanted a cantilevered kitchen, so they busted a hole in the patio to install a footer and also seem to have sunk a 6x6 in there for some reason. That hole is still damp somehow. There is also a cavity under the old patio exposed by the hole, which I assume is where the mosquitos are coming from.
Questions:
1. Does anyone know why they would have a single pressure treated 6x6 going diagonally towards the footer in a hole?
2. I want to fill the hole, but I don't want to compromise the 6x6 with organics, whatever the heck it is doing. Is filling the hole with sand&gravel crazy?
