Site walls and Frost Protection

Site walls and Frost Protection

Site walls and Frost Protection

(OP)
This is a questions that I have struggled with and I'm sure I will get a bunch of different answers.

I have a client who need me to design a cantilever retaining wall to support a roadway he is building (it is a road into a shopping plaza and will be subjected to trucking). The question I have is whether or not to provide frost protection on this wall. I am guessing that I should, but this will make the wall pretty tall in some areas and with the traffic surcharge (2' of equivalent dirt) it will make things even more difficult. Opinions?

RE: Site walls and Frost Protection

Depending on the your local code, you may be required to found the wall below the frost line. But perhaps more importantly, why wouldn't you want it below the frost line? Are you willing to accept the risk of the wall rotating due to uneven frost heave? Could be a disaster. Also, SOIL...c'mon man, its not just dirt (sorry, couldn't resist. Back in the day, I had a college professor that drilled it into our heads, its soil not dirt....and concrete, not cement)

RE: Site walls and Frost Protection

Absolutely. It should go down to frost.

When I am working on a problem, I never think about beauty but when I have finished, if the solution is not beautiful, I know it is wrong.

And timber not wood, as so stated by my materials testing prof who was British!
