Will 110 gal of water ruin my foundation?
I just purchased two of WaterPrepared’s 55 gal water tanks: https://waterprepared.com/products/blue-55-gallon-water-storage-tank. My plan was to store them in a corner of our outdoor shed, which is built on a concrete foundation. When I went to clear out that part of the shed, I noticed that there is severe cracking in the foundation all along the wall. See photo.
I don’t know if this is caused by:
1) the 400 lbs of water that is already stored on that side of the shed in 5 gal containers. But the water wasn’t stored in that corner–the row of 5 gal containers starts on the cardboard on the left side of the photo.
2) the current drought which is drying up our clay soil so that it contracts underneath the foundation. This is a major problem in our area; we have to put soaker hoses around our home’s slab foundation to keep it evenly moist or it will crack. We don’t have soaker hoses around the shed.
It’s only a shed, so I’m not very concerned about the foundation cracks. But I don’t want them to get majorly worse, like having that side of the shed sink 3 inches into the ground! Do I need to find a different place for the two 55 gal water tanks? Maybe putting them on the other side of the shed would be sufficient. I had hoped to be able to stack them in order to save space, which would mean about 900 lbs resting on about 4 sq. feet of space.
