I plan to build a 20' X 30' deck on the side of my house. I live near a rock quarry. There is occasional blasting at the quarry. This blasting causes my home to shake a little, but in almost eight years of living here the only damage my house has sustained is three drywall nails have popped out. I have been planning this deck for about two years. I have consulted the local codes department but they could not answer the two SPECIFIC questions I am about to ask. I have asked these questions on several other websites but all I get from anyone is general information about deck building, or links to general information. I do not need or want any more general information. I have two SPECIFIC questions that require two SPECIFIC answers. Considering my proximity to a rock quarry my questions are:
1. Should the deck be attached to the house or should it be free standing?
2. Should the columns/posts be in a post hole embedded in concrete, or should they be atop concrete piers? Either way the columns/posts will be built so they are NOT touching the ground.
Please consider my proximity to a rock quarry before answering. Also, if you do not have a SPECIFIC answer for these SPECIFIC questions, then please, please, PLEASE do not respond. Please forgive my bluntness, but I am sick and tired of getting answer, after answer, after answer, after answer, after answer that has nothing whatsoever to do with my questions. Thank you.
