Hello all, this is my first post here so please bear with me. Where do you go to find accurate frost depth/line values? At my job, we often have to design footers/foundations rapidly so as to get them to a costumer for the purposes of an estimate. Because everything needs done ASAP, contacting...
Hello, I am currently designing concrete drilled piers, and per the geotech report, the recommendations incur a 1600 psf design stress for potential frost heave. The recommendations also state that placing friction reducing material can be considered as an alternate option to prevent damage...
It's the same concept as using horizontally projected insulation as a building apron for shallow frost protected footings. That said, you may give consideration to adding insulation or other frost protective measures at the perimeter, where there is a greater chance for frost penetration.
I always hear that the footings have to be placed below the frost depth but does that apply to any footing? For a job where the local code indicates frost depth of 42”, all exterior bldg footings are placed at that depth but when it comes to the exterior stairs, they only go down 18” only!! The...
As a result of installing a centreline culvert in an existing highway the culvert appears to have settled, however from further investigation it was discovered that the moisture in the existing subgrade surrounding the installed culvert has cause frost heaving to occur causing a bump. Has...
