Flooring for Greenhouse

By Eric4home

We poured a concrete floor for our structure. After leveling the space by digging down a bit, we put up 8" forms. For the next step we put down recycled 3" closed-cell foam and covered it with poly. We left the center open for drainage and brick so we could access the power and water if repairs are needed. The pipe next to the shovel is the hydrant.The floor tilts to center 1"/3' to keep water from freezing the walls loose from the base.

Hi all
Suggestions for leveling a 10 year old greenhouse.

I got a nice recycled greenhouse from freecycle about 10 years ago and put it on some very solid slabs set in the ground. Over the years one corner has subsided about 1cm and the glass is now stressing and the door isn't closing squarely.

I was thinking about putting a few metal wedges or shimms about 2 feet apart on each side of the corner the sunken corner to bring it up (after taking the glass out of the roof on that side). Is this the best idea? Thanks!
