Water alone cannot adequately suspend, transport drill cuttings out of horizontal holes.

The grout serves as an integral part of a properly functioning heat loop system, and also creates a low-permeable seal through the length of the borehole. Follow these steps to ensure a good sample of grout for thermal conductivity testing.

For many applications, bentonite chips are sufficient. However, there are cases where the use of bentonite tablets is preferred.

The number of products available to drillers is constantly growing and, therefore, they face a never-ending learning curve. This column addresses some of the frequently asked questions we receive about grouts and sealants.

Any complex system requires regular maintenance in order to keep it running consistently and preserve the longevity of the system.

The use of graphite in thermally-conductive grouting applications has exploded in recent years with more and more drillers abandoning the use of sand either completely or partially.

In North America, state or provincial regulations work to ensure that wells are properly drilled and do not pose a threat to valued groundwater aquifers. An important aspect of completing a well is to grout the annular space between the drilled borehole and the casing.

Everyone can agree that safety has become an integral part of any construction site. We all have the same goal — to come home safely at the end of every day.
