Start out with a concrete slab about 20 years old. The pieces aren't even any more, and the expansion joints, made from 2x4's, have mostly rotted out. Time for replacement.
I rented an electric jack hammer, and busted up about half of the deck. I just about died. My back was sore for three weeks. I still had about 700 square feet to go. This just wasn't on.
That's more like it. I hired Bobcat Bob from Davis, and he had it all removed in a day and a half--even with pouring rain. He also had a load of dirt to help backfill where the slab had been removed.
I brought home a load of 36 cinderblock piers, and Sacramento Lumber Co. of West Sac. delivered the redwood, and I was off.
I rented a power auger and drilled out holes for the piers, for the deck was to be level with the house, rather close to the ground. I filled the bottom of each hole with gravel, tamped it down, and leveled each pier. Took about three days.
I laid down 4x4's to act as floor joists.
Finally I began laying 2x6's in a diagonal pattern. First one side. . .
Then the other. Took about a week every night after work; a few hours a day.
I cleaned up the area and attached a skirt board around the deck. Next I swabbed the deck with "deck cleaner", which lightened the wood considerably, and evened out the color.
Finally, I applied a transparent stain/sealer and UV blocker. Things are looking mighty good.
At last I can celebrate my new deck. Next project will be to improve the rest of the crappy backyard. I think I'll get started on the lawn soon.
