Rocky Mountain Geothermal, Inc. Provides a wide range of services to the Geothermal industry. Vertical Drilling Limited Access Drilling Loop Field Trenching Loop Field Headers Slinkey Pit Loops Large Excavation Horizontal Drilling Horizontal Fields Pipe Fusing Conductivity Testing Loop Field Flushing Vertical Looping Hard Rock Blasting Geothermal Headers Supply & Return Lines Pressure Testing Custom Vaults Mechanical Design     Vertical Drilling Mud Rotary - Air - Hard Rock Hammer Our crews have the experience and the capability to complete any geothermal drilling project, regardless of conditions. Our drilling methods include: mud rotary, air, and hard rock hammer with depths ranging from 0 to 1,500 feet. Limited Access Drilling Air - Mud Rotary - Hard Rock Air Hammer When access is limited or the terrain is too steep for conventional drilling methods, RMG possesses terrain-buggy-mounted drills. Drilling methods include: mud rotary, air, and hard rock hammer with depths ranging from 0 to 300 feet. Loop Field Trenching All of RMG’s equipment operators have experience and knowledge of utility installation. RMG assures a safe, clean, excavated trench, and that all locates of utility lines will be complete. Loop Field Headers All of RMG’s employees are IGSHPA certified in the methods of HDPE pipe fusion. Pipe fusion methods include socket, butt, side saddle, and electro-fusion. Our capabilities include fusing HDPE pipe from .5” to 24” in diameter. Slinky Pit Loops RMG’s employees have extensive experience in large pit excavation, as well as backfill and compaction. Our pit loops can accommodate a small residential house to a large commercial facility. Large Geothermal Excavation - Backfill - Compaction Our heavy equipment operators have extensive experience in large excavation projects including geothermal loop fields, pipe lines, utilities, ponds, as well as hard rock excavation projects. Horizontal Drilling Our horizontal drilling techniques allow us to place horizontally drilled loops under existing infrastructures such as football, baseball, and soccer fields, heavily treed areas and parking lots. Our capabilities include drilling and pulling geothermal loops at a depth of 15 to 20 feet and distances ranging from 0 to 500 feet. Horizontally Drilled Geothermal Loop Fields Geo Loop - Ready to pull back under football field 300' An example of a horizontally drilled loop being pulled back under an existing football field. Side Saddle Pipe Fusing All of our crews are IGSHPA certified in the techniques of geothermal pipe fusion, and they have extensive experience in all aspects of geothermal pipe fusion. Thermal Conductivity Testing In order to provide our clients with an accurate measurement of the thermal-conductivity value of the existing soil conditions, RMG provides thermal-conductivity testing on many of its large scale geothermal projects. Loop Field Flushing & Purging Large Lopp Fields are No Problem RMG is one of the few geothermal contractors in the Rocky Mountain region that has the ability to flush and purge large geothermal loop fields properly. Our flushing and purging units are specifically designed for the geothermal industry. The units have the ability to flush and purge at a rate of 450 gallons per minute; remove and filter debris; and mix the antifreeze to the proper percentage. Vertical Looping & Grouting Our looping and grouting crews have the ability to load and grout geothermal loops to a depth of up to 500 feet. Our state-of-the-art looping and grouting equipment ensures that each hole is properly grouted, and that the holes meet the thermal-conductivity value specified in the contract. In order to ensure the proper thermal-conductivity value of the grout, random samples are continuously taken and tested by an independent laboratory. Hard Rock Trenching & Blasting RMG performs a majority of its work in mountainous terrain where hard rock is a way of life. Our expertise in hard rock drilling and blasting techniques allows us to complete hard rock trenching and/or excavation. Geothermal Headers Supply & Return Lines Our crews have extensive experience in running geothermal supply and return lines. The lines are run from the loop field to the mechanical room. Pressure Testing All of RMG’s loop fields are pressure tested using air and hydro-static pressure test methods, thus ensuring a leak-free loop field. Custom Vaults RMG designs and installs custom geothermal vaults. These vaults are specifically designed on a per project basis to ensure ease of operation and maintenance. Mechanical Design RMG works closely with our sister company for turn-key design to build projects. Geo-Energy Services
