I am experiencing the same situation with my Workforce Cosmos shed that Robert K. Smith describes in his e-mail of 09/30/02. I assembled the 10x12 shed on a wooden foundation as closely to the directions as possible. The directions were very broad (bad) towards the end and also regarding main beam construction (drilling of holes, etc.). However, I do believe I assembled it correctly. I siliconed as per directions but I am getting 1-2 gals of water per 1" of rainfall leaking onto the floor.
Can anyone suggest a solution?
