I installed an underpad thinking it will prevent water from leaking in, which is not the case all the time. Also I chaulked all around the bottom of the shed, which again thought it would prevent water from coming in, which it hasn’t. I need a solution to stop water coming into the shed without starting from scratch. can someone help me, i am open to any suggestions Thank you

just dig a 1 ft by 2 ft deep trench around it and fill it wil gravel….will work fine…..if u ever build again….pour the slab and lay at least 1 course of block and set ur wall on those……

    Add more vents or even a powered vent if possible

    Try installing some flashing around the shed and use a cement adhesive. You might even want to double up the flashing. What I mean by that is put a roll around the shed and then start another maybe an inch away from the first roll. On your second roll, put some caulking under the flashing to help divert the water. You could also put some gutters on your shed to help divert the water. They make this black plastic pipe with holes in it for diverting water. Dig down into the earth enough that when it rains, the water goes into the pipe and away from the shed.

    I agree with Bigg__Dog, except that I would also seal the cement floor.
