So, yes, I always consider frost depth when designing my foundation depths. Here in the Northwest, I commonly use 18" as a minimum, but greater where required by the local jurisdiction. We talked aboth "what if" you dont go by the book but still want to design foundations at shallower depths. Due to additional cost, this method is typically only used where deeper trenching is not an option due to utility conflicts, shallow bedrock, or other conditions that make deeper excavation infeasible. Download Now Decomposing multi-patterned design layers into colors has traditionally been an exercise in finding at least one DRC legal coloring solution. What do you think?
The Ontario Building Code | Depth of Frost Penetration
By the way how do you know the true depth of frost penetration? Inaddition, I am finding that older versions of the building code allowed a foundation depth of 3'-6", now as people add on to their house, we find that their foundation depth does not meet the current code. The Eng-Tips staff will check this out and take appropriate action. Will there be snow cover or will the area around the structre be a parking lot with snow removed? Try to avoid plumbing leaks - or at least mitigate their impact if possible.
Water and sewage pipes are normally buried below the frost line to prevent them from freezing. Soil Glaciology Ground freezing Foundations buildings and structures. I myself yesterday in one of these forums called attention to flexural, lever or prying action, whatever, at fillet and butt welded tubes against a plate, subject to tensile force; to some this is a non-issue, for others a subject of interest. I am looking for something that would give some actual depth of frost for the coastal area. Frost Penetration and Movement air voids percentage of the soil matrix may be less for the road area assuming same material and less compaction
Water and sewage pipes are normally buried below the frost line to prevent them from freezing. Frost line depth I always recommend foundations isolated, strip or mats be located below the published frost depth. In the colder climate of northern USA states, with deeper "frost peroration", many non-heated buildings are on a slab on grade, yet heaving of the slabs seems to be a minimal problem, at least in my experience. So, yes, I always consider frost depth when designing my foundation depths. In Germany and UK temperatures in winter can be under -5C for lonnger then 7 days. I wouldnt call it black art just common sense Found an interesting article: Download Now Decomposing multi-patterned design layers into colors has traditionally been an exercise in finding at least one DRC legal coloring solution.
