Re: deck addition
Frost line across the country |
said by SparkChaser  :said by S_engineer :It works like this. A 2 or 3' hole down 8" in diameter. Once you've finished the hole, brush away all dirt around the hole so just the hole is exposed at ground level. Then you make a 1'square box with 2x4s. Cover the inside of the box with oil. Now center the box over the hole and fill with Concrete to the top of the box. 2' or 3' doesn't sound deep enough for WI. 2' wouldn't pass inspection even around here. You want to get below the frost line to prevent frost heave. The frost line is around 60" in the Dells area of WI according to the map, but check your local extension office if you want a specific number, or building department if you want what's required by code. |
