Grouting is a critical part of closed-loop ground heat exchanger installation. It is needed for environmental protection, borehole integrity, as well as thermal system performance. This session covers the important aspects of grout properties, selection and installation, with a focus on the additional challenges that occur when boreholes are drilled deeper. This session also introduces the latest developments in bentonite-based grouts that are available to help the designer avoid pipe collapse in deeper boreholes, without sacrificing thermal performance.
