frost lines
Soil freezing depths
Frost lines refer to the depth below ground level at which soil freezes during winter months, a critical measurement in construction and plumbing.
Building codes typically require foundations and water pipes to be placed below the frost line to prevent damage from soil expansion when water freezes.
The depth varies dramatically by climate—from near zero in tropical regions to several feet in northern latitudes.
The contractor had to dig the footings below the frost line to meet code requirements.
