How to insulate a shallow water line
How to insulate a shallow water line
(OP)
I am working on an office building project which has been completed, however the contractor installed the water line for the building sprinkler system approximately 36" below grade due to shallow bedrock. The frost line here is approximately 42" and the water within the sprinkler system will not be flowing unless there is a fire in the building, so we believe that there is a real pottential for the water within the line to freeze.
My question is: how can i determine an R-value for the soil above the water line? I plan on using this information to determine how much foam, preferably sprayed, to place around the sprinkler system distribution line. Thanks for any help.
