Sona Tubes are needed for a Deck, Front Porch or Three Season Addition

We started a new project yesterday in Manchester NH building a farmers porch or some people call a front porch.  The first step in building any deck or porch is put in the foundation, in this case we need to dig 6 sona tubes.  Most towns (such as Bedford NH, Amherst NH, Milford NH and Merrimack NH) only require the holes to be 8” wide and 4’ deep, Manchester requires the sona tube holes to be 10” wide by 4’, it might not sound like much of difference but when you are digging six of them it adds up.  The Manchester Building Inspector approved our holes and Keith and Jeremiah quickly filled them with cement to cure overnight.  Today the framing will begin.
