I hope you are checking back to see the newest suggestions, all of which may help your situation. I have a couple more, one involves practicing medicine without a license! - if arthritis is the problem with your knees - ask your doctor if you are a candidate for Synvisc or Hyalagan injections. I've had them, (a flu shot hurts worse) and they have greatly helped. It's a fluid that replaces the synovial fluid in the joint that gets absorbed as we grow older. Six months relief is considred a success, and insurance companies will pay for them. Cheaper than surgery! Worth looking into. Two summers ago, we made a "Square Foot Garden" and built two 3 ft.x 8 ft. boxes with 24 planting squares each, and one of them (it has a bottom on it) we placed on cinder blocks. I can plant,water and harvest standing up! It is small, so we do succession planting. You know it's my favorite spot. We plan on adding another this year. If you need more details just holler. I'll check back here. Dorothy

Depends. If the soil has ample amounts of organic matter now and an active Soil Food Web mixing in a high carbon source of material might have little to no adverse affect. However, if the soil lacks adequate amounts of organic matter and an active Soil Food Web, mixing a source of high carbon into the soil can result in the soil bacteria getting busy digesting that carbon and temporarily causing most of the available Nitrogen to be tied up. Once that carbon is digested, or mostly so, that N will be once again available to the plants.

Hi floorguy and Donna, Thank you so much for the response. How would I know the difference between gypcrete and real concrete? I was told it was concrete when I moved in. The guys who removed the popcorn complained that the downstairs ceiling is concrete, making it harder to remove the popcorn. Is the floater wood good for either type of concrete? If so, maybe I should stick with the floater type. Thanks a lot, jenny

Hi @Lynn Morford, I hate to jinx things, but now three months in, I LOVE the floors. I fact, I admire them many times a day (good distraction from current CV craziness). There are about a dozen spots where there were dings or tiny cracks, which freaked me out at first, but I'm pretty sure it was just from the movers. I do take care of them like a newborn child, though--sweep, vacuum, wipe, repeat. Overall, I'm very happy with them! @everdebz, we ended up gluing down. Definitely harder on my body that floating but I've learned to wear slippers or socks and I have yoga mats in most rooms to give my feet a little vacation as I walk through the house, lol. In the end, I trusted @joseph_corlett's comment about letting the contractor make the call on what is best for the situation. Granted, I still pine for the perfect floating feel of my old Junckers flooring, but apparently theirs were unique and most other flooring can't float the same way, so... Anyway, the sad fact is, you can't remove glue-downs without destroying the boards. So fingers crossed you never have to! (I put fake wood in my laundry room and we've already had three floods, so thank god for that decision.)
