I am looking at building a 24'x26' garage next summer, and wondering what kind of a base is necessary. Is a floating pad sufficient or would this require a proper foundation? (aka footings) Also how much would it cost?

I am located near Woodstock, between Hamilton and London.

It all depends where you are building the garage.

Hi Andrew,

A floating slab 24 x 26 will probably run you between 8 and 10K.+/- Most soil conditions are good for this type of foundation. A floating slab typically is min. 10" x 20" around the perimeter and Min. 4" slab. Use

re-bar metal re-enforcement rather then cheap wire or mesh if you don't want it to crack. Min. 4" of packed clean 3/4" stone. The form work and installing the re-bar can be done by you by direction from most concrete companies, but get a good concrete finisher to pour and finish the slab. (don't forget you're anchor bolts)

A floating pad or a foundation c/w footings are both acceptable methods for a build depending that both must be engineered. What is the frost protection in your area, what will the landscaping be like when done, what type of building is going up? VERY IMPORTANT, get a builder with proper knowledge to walk you through. I live in Kelowna B.C. so not possible for me to help out.If you need to keep cost down ask to be put on crew,

I am wanting to build a 1 storey 2 car garage. The frost goes down 4 feet in our area. I just didn't know if 24x26 was too big for a floating pad. Otherwise does anyone know if i cound use sauna tubes to build the structure from and just pour the floor?
