How do I install Pre-cast Concrete columns? In the interior of my home.[URL=http://www.pacificstone.net/CatSearch.asp?CatName=Columns]Like these[/URL] There are often seen as decoration around desk supports. They I have 4 halfs, 2 halfs will be joined around a 6x6 post the other 2 halfs will be placed flat against the wall on the other side of a pair of arches. I understand that they will be grout in the joints, but how do I anchor this babies to the post and to the side walls? I would not want my little one to bang into it and have one half peal off, nightmare. Thanks, Marc

My husband has requested that I build a porch on our mobile home. I would like to roof it to make it fully functionable. I know better than to attach the porch and roof to the trailer, but I am stuck. Our home has an overhang. I cant figure out how to place the roof supports near the trailer, yet still have the roof of the porch reach the roof of the trailer near enough to install flashing to prevent leaking. Could someone please point me in the right direction? Or at least tell me that "you cant get there from here?"
