Good Afternoon everyone,
I am brand new to this forum. I recently purchased an old house and I'm in the process of getting things set up. I know there will be plenty of projects to do on it (already we are removing wallpaper and painting) but I have one issue that needs fairly quick attention so I will begin my life on this forum with it.
The home is built on a crawl space. Most of the crawl space is accessible from the outside. However, a small addition (a mudroom) was added to the front of the house (not sure how long ago) and the crawl space under it is vented but the vent is not big enough to allow access into it. The only way to get in there that I can think of would be to go in through the top by ripping the floor out. I managed to snap a photo of the space through the vent and I can see that the joists are supported at the ends by what appears to be a 2X ledger, on it's side rather than on its end??? I would like to place a fairly heavy aquarium in that room and I am concerned about the weight of the water putting too much force on the ledger. The tank fully filled is probably about 700 lbs, plus the weight of any individual or individuals standing next to the tank. My concern is that since the 2X is on its side and it appears that the ends of the joists don't butt up fully with the concrete, that it could create a cantilever force that could rip the ledger out. Anyone have any thoughts on this possibility or some knowledge of how much weight those ledgers should be able to support?
Pictures of the crawl space are below.
