Geothermal Loop & Septic System Installations

Let's Dig!

Geothermal Loop Installation
We do the excavating, drilling and all other necessary ground work for the installation of closed loop ground source heat exchangers on geothermal heating and cooling systems. We do not sell equipment, nor do we work on air systems. We support any reputable manufacturers' products to insure its optimal performance. Our team works with the HVAC contractors to maintain customer satisfaction.

Durbin Enterprises respects the time, talent, and investment that our clients employ to search for the best loop field for their site. Our installation crews and drillers are licensed, trained professionals. Each member meets the health and safety requirements as mandated by OSHA 29 CFR 1910.120 and the State regulatory agencies governing our work. We are also International Ground Source Heat Pump Association accredited installers.

Drilling Services
Skilled in a wide variety of drilling techniques and applications, our field personnel evaluate, react to site conditions and use appropriate drilling methods and procedures to meet the design objectives.

Our inside piping and fusion crews have been certified by Climate Master, Phillips Drisco, Water Furnace and Vanguard.
We offer a three-year warranty on our workmanship. We use pipe with at least a 50-year leakage warranty.

Horizontal Loop Fields
We offer a variety of choices for horizontal geothermal loop fields because we can choose from a wide variety of excavating equipment, ranging from small finish tractors to large track hoes, back hoes, and even bulldozers. We can help you with a design that will fit both the land constraints and project budget.

Earth Contact
Earth contact is very important to the performance of a loop field. Our vertical bores are 100 percent grouted from bottom to top using a geo-loop 50/500-grout pipe. We use E-Z Seal Bentonite grout. It is premixed with polymer to insure proper consistency. Special thermally enhanced grouts are available for commercial applications.

Pond Loops
Together with the help of top industry engineers, we developed an innovative aqua rack for pond loop installations. The rack keeps the loops above the silt layer of the pond and helps space the loops evenly. This allows the best heat transfer during both the cooler and warmer seasons. Without the rack system, pond loops may rest in silt and then provide inconsistent heat transfer rates. The aqua rack shown on the left is for a five-ton loop in southern Illinois.
