Not jeep related, but we spent the weekend (last weekend too) redoing our backyard. The deck I have no idea how it was still standing, most of the joists had pulled free (which explains why it was shifting away from the house). I found a ton of dry rotted wood. A mixture of pine, cedar, treated and non treated. Various types of screws (torx, square, phillips all ranging from 2 to 3.5").
You can see the separation from the first step in this photo.
This also explains why we had such a sag. Most of the joists had pulled free. Whoever built this did a horrible job. Some joists were held by two nails. Some had 6. It was really a half-assed job. The stair from the door was not even supported by anything, the corner support was loosely placed, literally just resting.
We put sod all around this weekend. That was a ton of work, much harder than I originally anticipated. Next weekend we plan to build a much smaller patio/deck. It will probably be 8x12 and built correctly this time.
Also, heres what a 17x10 deck looks like chopped up into a bunch of pieces
. I had 4 trips loaded like this.
