U.I.P.® pre-insulated pipe can be installed in the active frost zone (with low wattage electric tracing if necessary) and resist freezing. The use of GF Urecon pre-insulated pipe has permitted hundreds of northern communities to obtain year round piped potable water, resulting inmajor social and health benefits. Savings are greatest when rock is encountered as it is far less expensive to pre-insulate and shallow bury water and sewer pipes than to blast and deep bury in rocky conditions.
In sandy or poor soil conditions, experience has shown that a considerable width to depth ratio is often required for excavation to permit conventional burial of pipelines below the frost zone. A GF Urecon pre-insulated pipe system, shallow buried (with low wattage electric tracing if necessary) could result in the excavation of one tenth the earth volume otherwise required. Substantial cost savings are thus realized and the danger to workers in deep trench conditions is avoided.
