Anyone who has walked on a hot, sunny beach knows that sand is a good insulator. Dry coarse grained sand may be used as a substitute for the insulation required by code in a buried pipe situation. The sand should have a maximum particle size of 1/4” and a moisture content of 1% or less.2014-09-29
Is sand a good insulator for water pipes?
Sand is a better insulator than soil with a high clay content. That makes dry, coarse-grained sand an effective and very cost-effective choice of backfill material when it comes to the insulation of shallow water lines. Using sand in this way can help to prevent the buried pipes from freezing.
Why is soil a good insulator?
Going down, the pressure (weight of soil above the point) start to make effect, so we will have higher temperatures). So, soil is a good insulator. The good: average temperature is usually (but in very cold regions and mountains) above freezing point.2017-11-22
