Thanks to all for the reply's. I went ahead and mounted a sheet of plywood to the wall last night and after a few coats of paint I'll go ahead and slap everything up on it. 79rallysport, glad to hear you've had great success with your setup. I'll be using mine to heat a 600 sq ft garage and...

Thanks, I had heard that before and at the same time I've heard to remove all fill that may have been placed in the ground during the construction. I thought that last part needing the fill removed was a little much as I imagine any fill placed in the ground during the construction would likely...

Hello, I'm going to be pouring a monolithic slab for my upcoming garage build and I want to obtain information on depths of excavation. The building is being built in Ottawa, ON, Canada. How deep should I go to evade cracking in my concrete? Should I be going deeper around the footings of the...

Updated, thanks

I'm in the process of building a garage 592 sq ft. I got my permits and everything approved from my city. The city requested a grading plan and in the plan suggested a foundation with a proper footing and walls that are just under 6' tall. I've sent it out to some foundation contractors in my...
