Pier

I am looking for suggestions on putting in a pier for my observatory. What piers are availble and what are the pros and cons. I dont have a problem dropping cement 48" deep but the top of the cement w/ bolts needs to be 12" underground. If I move I just want to fill in the ground and leave the cement as is. So something that I can bolt to the cement base.

Thanks,

Matt,

I hear you are putting in a nice observatory. Good luck with the project. I was under the impression that you need to get below the frost line with the cement block. Since I have no frost line anymore, being in warm country now, I am not sure about that.

If you are going to do it perfectly, then remember isolation of the pier from everything that you are going to be walking on.
