Guides in this topic
How deep should pipes and foundations go?
Separate frost protection, pipe cover and structural foundation design before digging.
Prepare the house before the first hard freeze.
Walk through exposed water systems, heating dependencies and outage actions while there is time to fix them.
Protect exposed pipes before relying on heat trace
Reduce exposure, insulate correctly, choose controls and plan for a power failure.
Turn frost requirements into foundation levels on site
Separate the local frost criterion, structural bearing level, final grade and excavation level before digging.

Calculators in this topic
Pipe cover to trench depth
Convert an established pipe-cover requirement into a trench section.
Heat-trace energy use
Estimate connected load and energy use for a thermostatically controlled heating cable.
Foundation frost-depth screening comparison
Compare a planned bearing depth with a locally established frost-protection target.
Foundation bearing and excavation elevations
Translate final grade, bearing depth and a working layer into site elevations and excavation depth.
