Anchor shed to slab

[MerlinsBeard]

I couple weeks ago I had a slab poured and my wife and I have been trying to keep it wet as best we can. The shed will probably be finished by end of May. The 28 days from the pour is on June 3rd so about 12 days left. Plan to try to keep it wet for 28 days. Question is how long after we stop keeping the slab wet to let the slab dry before the shed can be anchored?

I would think that you are already at 80% + strength. I don't think you need to let it dry any after 28 days and I have seen anchors put in way before 28 days without a problem. It is good you have kept it wet; that helps it develop its rated strength.

Yep, way before the 28 days for such a light load. I've been on projects where we strip forms the day after the pour & immediately set structural steel for piperacks - only placing 5-10% of the final loads. For towers & major vessels, elevated concrete we do often wait 14-28d depending on the project critical path of work. Congrats on the shed!

Couple days after pour.

I t depends on how close the anchors are to the slab edge and anchor type. Wedge anchors near the edge, I'd want at least two weeks. Epoxy (my preference), a couple of days. JMHO

Like always the answers are not crystal clear.
