Re: [Bennie García] Making a concrete addition to a Home

Thanks for the straight forward answers, they are appreciated. I have all the tools and a pretty good supply of hog rings from previous upholstery projects. In your experience, what size hog rings are better suited than others for such a project?
What other details might you want? I am particularly concerned about two entirely different materials and ground settling, that can most likely cause a roof leak at the adjoining seems of the new structure to the older structure. I have used in the past o larger commercial architectural projects a rubberized membrane at such connecting places. Have you ever sued such material and what luck have you had using that material, if you have used it? I also use the same material around all window headers and door headers.
Have you ever used, or ever seen any other such flexible material for such a joining of two different structural materials that allow for small movement or settling over the years?
The existing home has been in place for more than 20 years and is pretty well settled. My concern is the new structure weight and new settling that is almost surely to occur. While a great amount of thick rock (medium grade Cantara) is in the subsurface, there are sufficiently large enough spaces of deep earth in gaps of the geological subsurface. Exactly the locations of such differences are not possible to tell, for my budget. I thought of using a double size footing shoe (not height) on the new addition that may well distribute the weight better and more uniformly, than a usual size footer shoe for such a project. What is your opinion on that process.?
In México, it has in the past, been an issue that asbestos is many times used as a bonding material in the concrete mix, for me that is a killer. I already have a good case of 50% service connected asbestosis from my time in the Navy. I really do not want any more exposure under any circumstances. Do you know if that is still the case generally speaking here in Mexico? I have found many people here do not even check the composition of the various building materials they use in their construction. If that is the case for those people, and they are happy about their decision, that is fine by me, I am happy for them. In five or ten years time when they start to have separation or sinking problems, with cracks appearing in the walls and / or floors, with leaks all over the place from a displaced roof, then they start crying and bitching. I prefer to do my homework ahead of time.
Five or ten years from now, I may not be around to worry about such things, but my wife (much younger than me) and our children will be. I don't want them to be saddled with such problems or unnecessary expenses for repairs, after I am gone. I respect others choices for themselves, but please (I) don't (want them (others to)) ask me (not you) to follow their opinions, when I know there can be really serious and expensive repercussions, at a later time using bad decisions in initial construction. It is much easier to build new that is for sure, as you well know. Remodeling using additions among other things are a real headache, if not constructed properly.
Just chalk my response up to my being a cranky old man, who is in some cases, a perfectionist. Not always successfully so, but a half assed perfectionist none the less.
Thanks again for the straight forward answers and suggestions.
