I guess waterproofing would be water,water is pretty much water where ever you go I think. Lets not turn this into rocket sicence I just wanted some inexpensive ideas on what to put between the concrete and the base of the shed. thanks

Welcome to the forums setad!

Would caulking work? how big of a gap do you have? Are you just concerned with rain or is there water running across the ground getting into the shed?

It is a very good match with the two metal to concrete and will rivit down the shed once I have some type of sealant between the two. but I need somthing that will stay open long enough to go all the way around a 10 x 14 shed and let it back down without having the start dry out before I get all the way around, and not spending a ton of money. will silicone stay open long enough? the slab is bigger than the shed so rain might come off and go on the concrete and into the shed or when Iwash down the sidewalk leading to the shead with the hose.The shed has a nice 1/2 in lip to create a seal but I need somthing to stay open long enough to do it all at once lift the shed up put in the sealant and let the shed back down.A garage door seal would work but they don't give those away.or do they?

I'm sure there is a roll of something you could use, just not sure what it would be

If using caulking, I'd erect the entire shed and the lift up one side at a time to apply the caulking and then finish tightening the base of the walls down.

You can get rolls of foam sill plate seal at home stores. It looks like 3-1/2" wide foam tape.

WOW thank you so much for your post. I looked up foam sill tape and the cost is right down my ally 25.00 for 50 feet and says it will fill in all gaps when sandwiched between the two surfaces and is 2*1/2 inches wide. I have no dout this will work for me and thank you so much this made my day.

Might be good...but it's more designed for sealing air, insects and separating wood from concrete. It will eventually degrade if exposed to sunlight. Most ties when it's used in construction it's completely covered by siding or similar. If you use it I'd probably trim it flush on the inside (if the shed has no floor) or outside and use silicone caulk or Poly caulk.

the shed has a concrete floor that extends 5 inches all the way around would the sill tape degrade between the two or seal out water? how long will silicone stay open? no sun light can hit it between the concrete and the bottom of the shed but then will it keep out water? the shed will also be rivited tight to the concrete, What do u think of the plumbers putty idea?

Plumbers putty eventually hardens and cracks.

A solution using silicone caulk involves setting it perfectly aligned on four small pieces of wood. Spread the caulk. Have a helper hold the shed up as you remove a block and add a bit of caulk where the block was. Do one end and lower it to the concrete and then do the other end. I'd let the caulk set up before tightening it down so you don't squeeze out all the caulk.

Well I think I'm back to the silicone and the blocks are a good idea. thank you all for helping me decide. I guess the internet is not as bad as I thought. Thanks everyone.

Use either an elastomeric caulk or butyl rubber. Silicone will deteriorate with sunlight and crack. Both elastomeric and butyl rubber will give and take with the seasons and won't crack. You have metal and concrete, two dissimilar materials going together and they will move at different rates. Install the foam sill seal, but keep it flush to the outside. You can cut the waste on the inside if you wish. Then go back with the sealant .
I believe it has been brought up, you should have proper drainage around this shed, as nothing will keep rising water out for long.
