In high-production geothermal drilling, efficiency is measured by more than how quickly a drill rig completes a borehole. The real measure of productivity is how efficiently crews can install geothermal loops, mix grout, and complete the grouting process before moving to the next hole.
For contractors managing large residential developments, commercial geothermal projects, and multi-borehole ground source heat pump installations, traditional looping and grouting methods can create costly bottlenecks.
The Bore Logic GeoTherm Logic 5.5 (GTL 5.5) was designed to eliminate those inefficiencies. By integrating geothermal loop loading, automated grout mixing, high-capacity pumping, and material handling into one track-mounted machine, the GTL 5.5 delivers a comprehensive solution for production geothermal drilling contractors.
One Machine. Three Critical Geothermal Operations.
Traditional geothermal installations often require separate equipment for loop handling, grout mixing, and grout pumping. Each machine requires transportation, setup, positioning, and operator attention.
The GTL 5.5 consolidates these essential operations onto a single crawler-mounted platform.
Its integrated configuration includes twin grout mixers, a 475-gallon hopper, automated mixing and pumping controls, a powered geothermal loop loader, and an onboard grout hose reel.
For production drillers, this means fewer pieces of equipment to coordinate, less time spent repositioning machinery, and a more efficient workflow between boreholes.
High-Capacity Grout Mixing for Continuous Production
One of the biggest challenges in geothermal grouting is maintaining a consistent supply of properly mixed grout.
The GTL 5.5 addresses this challenge with two 92-gallon grout mixers, providing a combined 184 gallons of mixer holding capacity.
This dual-mixer configuration allows crews to coordinate grout preparation and pumping, reducing interruptions between batches and helping maintain a steady production rhythm.
The integrated 475-gallon hopper further streamlines material handling, while automated mixing controls help operators maintain repeatable grout preparation procedures.
For contractors completing dozens of geothermal boreholes per day, minimizing waiting time between grout batches can make a meaningful difference in overall productivity.
Powerful Grout Pumping for Deep Geothermal Boreholes
Effective geothermal borehole grouting requires equipment capable of delivering material through the grout line at the pressures and flow rates demanded by the installation.
The GTL 5.5 features a grout injection pump rated at 22 gallons per minute and 360 PSI, providing the pumping capability needed for a range of geothermal grouting applications.
An integrated hose reel accommodates approximately 980 feet of grouting hose, helping crews manage hose deployment and retrieval without relying on separate hose-handling equipment.
This combination supports efficient grout placement while reducing the time spent organizing hoses and preparing equipment between boreholes.
Actual pumping performance depends on grout properties, hose configuration, borehole conditions, and operating requirements.
Integrated Geothermal Loop Loading Reduces Manual Labor
Installing geothermal loops is physically demanding, particularly on projects involving repeated loop installations throughout the day.
The GTL 5.5 incorporates a powered geothermal loop loader directly into its chassis, simplifying the handling and installation of ground heat exchanger loops.
Instead of relying entirely on manual handling or separate loop-loading equipment, operators can use an integrated system designed around the geothermal installation workflow.
Reducing repetitive handling can help limit operator fatigue, improve crew coordination, and allow workers to focus on productive installation activities.
For contractors operating multiple geothermal drill rigs, these efficiencies become increasingly valuable as project volume grows.
Track-Mounted Mobility for Demanding Jobsites
Geothermal drilling projects frequently involve challenging terrain, soft ground, limited access, and changing equipment positions.
The GTL 5.5’s track-mounted chassis provides the mobility needed to position grout mixing and loop-loading equipment throughout the jobsite.
Rather than moving several independent machines between drilling locations, contractors can reposition one integrated system.
This approach simplifies jobsite logistics and helps maintain an organized work area, especially on large commercial geothermal loop fields.
An onboard Kubota diesel engine supplies independent power, while optional equipment, including a loader crane, generator, and pressure washer, allows contractors to configure the machine for specific operating requirements.
Lower Operating Costs Through Smarter Equipment Integration
For production geothermal contractors, profitability depends on controlling the cost of every completed borehole.
Labor, equipment mobilization, material handling, setup time, and operational delays all influence project margins.
The GTL 5.5 is designed to address these cost drivers through equipment consolidation and automation.
By combining multiple geothermal installation functions into one platform, contractors can potentially reduce support equipment requirements, improve labor utilization, and limit nonproductive time.
The result is an opportunity to complete more geothermal loop installations with a more streamlined crew and equipment configuration.
Built for Production Geothermal Drillers
The GTL 5.5 is particularly well suited for geothermal contractors focused on repeatable production, consistent grout preparation, and efficient loop installation.
Whether supporting residential geothermal developments or large commercial ground source heat pump systems, the machine brings the essential looping and grouting processes together in one purpose-built solution.
For contractors looking to scale production without adding unnecessary equipment complexity, the GTL 5.5 offers a compelling approach to geothermal jobsite efficiency.
