Grout. One of the most important determinants of an EHX's performance - and hence its required size and its associated cost - is the quality of the grout used to seal each ground loop within its borehole to the adjoining earth. EnLink's grouting system is compatible with all major grout types.

U-bend. At the bottom of every EHX ground loop is a U-bend. EnLink has designed a special U-bend to work in conjunction with its CTU loop insertion rig. It quickly and easily slides down a borehole.

EnLink also uses polyethylene pipe of the highest quality from leading manufacturers.
