Directional Drill Financing for Underground Construction in the U.S.

Horizontal directional drilling equipment can let an underground contractor install conduit, fiber, water, gas, electrical, and other infrastructure without opening a continuous trench across the jobsite.

The financial challenge is that buying the drill is rarely the whole project. Drill rods, tooling, reamers, locating equipment, fluid systems, trailers, and mobilization can substantially increase the cash required before the first bore is completed.

Quick Answer: U.S. underground contractors can finance or lease new and used horizontal directional drills, often with qualifying rods and hard support equipment. Approval typically depends on cash flow, credit, existing debt, drill age and hours, equipment value, seller quality, down payment, contracts or utilization, and whether the requested term fits the machine's remaining useful life.

Businesses starting with an ownership-focused structure can review Mehmi Financial Group's equipment loan options. Contractors comparing an end-of-term purchase option or different replacement cycle can also review its equipment leasing options.

What directional drilling equipment can be financed?

Financing can potentially cover compact utility drills, mid-size horizontal directional drills, large HDD rigs, and directly related hard equipment when the equipment, seller, and business qualify.

That covers a very wide collateral range.

For example, Vermeer's current D8x12 compact drill is rated at 7,850 pounds of thrust and pullback, while its substantially larger D100x140 S3 is rated at 100,000 pounds of thrust and pullback. The machines also differ considerably in weight, tooling, transportation requirements, and operating costs.

That is why an application should not simply say "directional drill."

Provide:

  • Manufacturer and model.
  • Model year.
  • Serial number.
  • Engine and drilling hours where available.
  • Thrust and pullback capacity.
  • Rotary torque.
  • Drill rod size and length.
  • On-board rod capacity.
  • Mud pump specifications.
  • Weight and transportation requirements.
  • Tooling included in the sale.
  • Seller and purchase price.

Contractors specifically operating in Texas can also use Mehmi's Texas directional drill financing guide for a state-specific treatment of the same equipment category.

How does directional drill financing work?

The basic structure is straightforward: an approved financing provider funds an eligible portion of the equipment acquisition and the business repays the obligation over an agreed term.

The underwriting is not as simple.

Credit evaluates both sides of the transaction:

The borrower: Can the underground construction company reliably support the payment?

The equipment: Is the drill identifiable, correctly valued, marketable, insurable, and likely to remain productive through the requested financing term?

This is similar to how other specialized construction assets are evaluated. Mehmi's excavator financing guide for Michigan businesses shows the same basic relationship between business cash flow, machine condition, existing debt, seller quality, and remaining equipment life.

What does credit look for from an underground contractor?

The strongest HDD financing request connects the machine to real operating economics.

Credit may review:

  • Time in business.
  • Owner and management experience.
  • Directional drilling experience.
  • Historical revenue and profitability.
  • Recent bank activity.
  • Current liquidity.
  • Existing equipment loans and leases.
  • Business and personal credit where applicable.
  • Customer concentration.
  • Current contracts and backlog.
  • Existing drill utilization.
  • Rental or subcontracting expenses the purchase will replace.
  • Reason for adding or replacing equipment.

The distinction between replacement and expansion is especially important.

Replacing an HDD rig that is already working every week can be relatively easy to explain. Management can show its existing production, repair history, downtime, rental replacements, and customer demand.

Adding a second, third, or fourth drill requires another question: is there enough profitable work and labor capacity to keep the additional machine busy?

The same issue appears in multi-unit construction equipment purchases. Mehmi's Dallas multi-unit skid steer financing guide explains why credit looks at the combined debt obligation and whether the business has enough work to use every machine.

Why do HDD specifications matter to financing?

The drill needs to fit the contractor's normal work.

A compact telecommunications contractor installing shorter conduit runs in developed neighborhoods has different equipment needs than a pipeline contractor completing long, large-diameter crossings.

Important HDD specifications include:

  • Maximum thrust.
  • Maximum pullback.
  • Spindle torque.
  • Rod diameter.
  • Rod length.
  • Minimum and planned bore diameter.
  • Drilling-fluid flow and pressure.
  • Machine dimensions.
  • Machine weight.
  • Ground conditions the drill is designed to handle.

Buying substantially more machine than the business needs can create a larger payment, higher transportation expense, more costly tooling, and greater maintenance exposure without creating enough additional revenue to justify those costs.

Buying too little drill creates a different problem if crews repeatedly operate near the machine's capacity or have to turn away larger jobs.

Credit does not engineer the bore plan, but a financing request is stronger when management can explain why the selected machine fits the company's actual project profile.

Can used directional drills be financed?

Potentially. Used HDD equipment can make strong financial sense when the purchase price, remaining life, maintenance history, and expected utilization justify the transaction.

Hours alone are not enough to evaluate a used drill.

Review:

  • Engine condition.
  • Hydraulic pumps.
  • Thrust and rotation system.
  • Carriage.
  • Spindle.
  • Rod loader.
  • Vice system.
  • Undercarriage.
  • Tracks, rollers, idlers, and sprockets.
  • Electronics and controls.
  • Mud pump.
  • Cooling system.
  • Emissions equipment.
  • Major repair and rebuild history.

Whenever possible, operate the drill under load and inspect it after it reaches normal operating temperature.

A low-hour HDD rig with poor maintenance can be a worse credit risk than a higher-hour machine with documented preventive maintenance and recent component work.

The same principle applies to other used earthmoving assets. Mehmi's New York excavator financing guide explains why age, hours, condition, purchase price, and remaining productive life should be evaluated together instead of relying on one number.

Should you finance or lease the directional drill?

Financing generally deserves the first look when the contractor expects to keep the drill for most of its productive life.

A lease may deserve consideration when the company replaces high-utilization equipment on a planned cycle or wants a defined end-of-term structure.

Mehmi's College Park excavator EFA-versus-lease guide illustrates the same ownership decision for another high-value construction asset.

Do not compare the structures based only on monthly payment.

Review:

  • Upfront cash.
  • Payment amount.
  • Payment frequency.
  • Term.
  • Financing charges.
  • Documentation or origination fees.
  • End-of-term purchase amount.
  • Fair-market-value obligations where applicable.
  • Early-purchase or early-payoff terms.
  • Personal guarantees.
  • Security and UCC filings.
  • Equipment return conditions.
  • Total amount required to become the owner.

A lower scheduled lease payment may simply mean a larger amount remains at the end.

Can rods, reamers and HDD support equipment be financed?

Potentially, particularly when durable equipment is directly connected to the drill and itemized in the original purchase proposal.

A complete HDD package might include:

  • Directional drill.
  • Drill rods.
  • Reamers and backreamers.
  • Drill heads.
  • Mud mixing system.
  • Fluid pumps.
  • Rod handling equipment.
  • Equipment trailer.
  • Other durable support equipment.

Consumables should be separated.

Bentonite, additives, fuel, disposable wear items, wages, and normal job expenses are working-capital needs rather than the same type of collateral as the HDD rig.

Do not tell credit that the transaction is $275,000 if the company already knows it needs another $80,000 of rods and support equipment before the machine can perform the intended work.

Submit the real acquisition cost upfront.

Contractors buying smaller supporting machines can also review Mehmi's Iowa skid steer financing guide for an example of how attachments, equipment condition, and cash-flow fit affect a construction-equipment request.

What if the directional drill requires a deposit?

Custom or built-to-order HDD equipment can introduce another financing issue: the manufacturer may require money before the completed machine is available for normal equipment funding.

The payment schedule could include a deposit at order, fabrication milestone payments, payment before shipment, and a final balance after acceptance.

Do not assume an equipment approval automatically covers every pre-delivery payment.

Before paying a large non-refundable deposit, determine:

  • Who must fund the deposit.
  • Whether the financing provider will reimburse an eligible deposit.
  • Whether progress payments can be accommodated.
  • What documentation is required at each stage.
  • When normal financing payments begin.
  • What happens if production or delivery is delayed.

The cleaner approach is to show the complete vendor payment schedule when the financing request is first submitted.

What documents should you prepare?

For a directional drill purchase, prepare a file that proves who is borrowing, exactly what is being acquired, and why the payment is supportable.

Documents may include:

  • Completed business application.
  • Ownership and entity information.
  • Equipment quote or purchase agreement.
  • Year, make, model, and serial number.
  • Hours and complete drill specifications.
  • Itemized rod and tooling package.
  • Photos and operating video for used equipment.
  • Maintenance and major repair records.
  • Recent business bank statements.
  • Business financial statements.
  • Tax returns where required.
  • Year-to-date profit-and-loss statement.
  • Balance sheet.
  • Existing equipment debt schedule.
  • Project backlog or major contracts when relevant.
  • Proof of down payment.
  • Insurance information.
  • Seller ownership documentation for private sales.

Private sellers may require additional verification because the financing provider cannot rely on the same documentation process used by an established equipment dealer.

How should you evaluate the payment?

Start with conservative incremental cash flow rather than project revenue.

Assume an illustrative U.S. underground utility contractor purchases the following package:

  • Used directional drill: $285,000
  • Rods, reamers and qualifying hard equipment: $65,000
  • Total purchase: $350,000
  • Down payment: 15%, or $52,500
  • Amount financed: $297,500
  • Assumed nominal annual interest rate: 9.50%
  • Term: 60 months
  • Payment frequency: monthly
  • Illustrative documentation fee: $3,500 paid separately
  • Taxes, insurance, transportation, repairs, drilling fluid and operating costs: excluded

Using a standard fully amortizing loan calculation, the estimated payment would be approximately $6,248.05 per month.

Over 60 months, scheduled payments would total approximately $374,883.22, including about $77,383.22 of interest.

Including the $52,500 down payment and the illustrative $3,500 fee, total cash paid would be approximately $430,883.22 before excluded costs.

Scheduled annual debt service is approximately $74,976.64.

That is what management needs to compare against the drill's incremental economic contribution.

If ownership saves $150,000 per year of rental and subcontracting costs but adds $60,000 of maintenance, transportation, insurance, and other ownership costs, the net identifiable benefit before financing is about $90,000.

A nearly $75,000 annual payment leaves little room for errors in those assumptions.

The business should either document additional economic benefit, negotiate the acquisition price, contribute more cash without damaging liquidity, choose another structure, or reconsider the purchase.

These numbers are illustrative only. They are not a Mehmi Financial Group offer, approval, APR quote, or representation of currently available pricing.

How much money down is required?

There is no universal down payment for directional drill financing.

Required equity can change according to:

  • Credit strength.
  • Operating history.
  • Purchase amount.
  • Equipment age.
  • Hours.
  • Manufacturer and model.
  • Equipment condition.
  • Seller type.
  • Valuation.
  • Existing debt.
  • Available liquidity.

More cash down can lower the financed amount, but underground contractors should not empty their operating accounts simply to reduce the equipment payment.

The company still needs liquidity for payroll, drilling fluid, tooling, utility locating, transportation, repairs, insurance, fuel, and receivable delays.

Businesses that already own substantial equipment may instead evaluate equipment refinancing or sale-leaseback options, subject to equipment value, existing liens, cash flow, and provider requirements.

What insurance and lien issues can delay funding?

Insurance is normally a closing condition rather than something to arrange after the equipment is delivered.

The policy and certificate may need to identify the correct borrower, equipment, coverage, deductible, and financing provider's interest.

Mehmi's Fort Worth wheel-loader insurance guide explains how an otherwise approved heavy-equipment transaction can still stall when the insurance documentation does not meet funding requirements.

Security documents also matter.

Depending on the financing structure and applicable state law, a financing provider may file a UCC financing statement or take other security interests. Determine whether the security is limited to the purchased drill or extends to other business assets.

Also understand:

  • Existing blanket liens.
  • Prior liens on used equipment.
  • Personal guarantees.
  • Cross-collateralization.
  • Early-payoff provisions.
  • Default remedies.

Have legal counsel review provisions you do not understand.

Do 811 requirements matter to an HDD contractor?

Yes operationally, although financing approval does not replace jobsite compliance.

PHMSA describes 811 as the nationwide one-call system used before excavation so underground facility operators can identify and mark affected infrastructure. PHMSA notes that state laws govern the process and required timing.

For a financing decision, this matters because HDD utilization assumptions should reflect real operating conditions.

Permitting, utility locating, traffic plans, bore engineering, easements, weather, restoration requirements, and job sequencing can all affect when the drill actually earns revenue.

Do not underwrite your own purchase as though every scheduled day will become a billable drilling day.

Can SBA financing be used for a directional drill?

Potentially.

The SBA states that 7(a) loan proceeds can be used for the purchase and installation of machinery and equipment. The current maximum 7(a) loan amount is $5 million, subject to SBA eligibility and participating-lender underwriting.

SBA 504 financing can also cover qualifying long-term machinery and equipment, but SBA specifies that the machinery or equipment must have a remaining useful life of at least 10 years.

That requirement can be significant for a used directional drill.

An older, high-hour HDD unit might work for conventional equipment financing but not satisfy the useful-life requirements of a particular SBA 504 transaction.

SBA financing also involves different documentation and eligibility considerations, so compare it with conventional equipment finance based on total cost, timing, collateral, paperwork, and the company's complete financing need.

What tax deductions may apply in 2026?

A U.S. tax professional should review the exact acquisition and financing structure.

For tax years beginning in 2026, IRS Publication 946 states that the maximum Section 179 deduction is $2.56 million, with the deduction beginning to phase out when qualifying Section 179 property placed in service exceeds $4.09 million. Other limitations and eligibility requirements apply.

The IRS also states that certain qualifying property acquired and placed in service after January 19, 2025 is eligible for a 100% additional first-year depreciation deduction, commonly called bonus depreciation, subject to applicable rules and elections.

Do not purchase a directional drill solely because a potential tax deduction makes the first-year numbers look attractive.

The equipment still needs to generate enough cash to support its payment and operating costs.

When is buying the drill a poor decision?

Renting, subcontracting, or delaying the purchase may be better when utilization remains uncertain.

Warning signs include:

  • The expected contracts have not been awarded.
  • One speculative customer justifies most of the purchase.
  • Current drills already have significant idle time.
  • The company cannot staff another crew.
  • The down payment would consume most liquidity.
  • A used drill has unresolved hydraulic or drivetrain concerns.
  • The requested term exceeds realistic remaining equipment life.
  • The business is already carrying excessive equipment debt.
  • The payment works only during the strongest months.

For another U.S. construction example, Mehmi's Florida dump-truck financing guide applies the same principle: a strong construction market does not automatically make an individual equipment payment affordable.

A financeable transaction and a financially sensible transaction are not always the same thing.

FAQ About Directional Drill Financing

Can a new underground construction company finance an HDD rig?

Potentially, but limited operating history can increase scrutiny. Relevant operator experience, adequate cash reserves, clear contracts, reasonable equipment size, down payment, and a marketable drill can strengthen the request. Providers establish their own eligibility and guarantee requirements.

Can a high-hour directional drill be financed?

Potentially. High hours make condition, service records, major rebuild history, hydraulics, undercarriage, rod handling, and remaining useful life more important. A shorter term or additional equity may be appropriate depending on the machine and financing provider.

Can I finance a directional drill from a private seller?

Potentially. Expect additional verification of the seller, serial number, ownership, lien position, equipment condition, purchase price, and payment instructions. Do not send a significant deposit until ownership and the financing process are clear.

Can several HDD rigs be financed in one transaction?

Potentially. Credit will evaluate the combined purchase amount and payment obligation. The application is stronger when the contractor can show enough operators, crews, locating resources, support equipment, liquidity, and confirmed work to keep every drill productive.

Can locating equipment and trailers be included?

Potentially, when durable equipment is directly related to the acquisition and clearly itemized. Eligibility varies by provider. Submit every component at the beginning rather than adding equipment after the main drill has already been approved.

Is leasing better than a loan for an HDD rig?

It depends on ownership plans and replacement cycles. Contractors keeping a drill for most of its useful life may prefer an ownership-focused structure. Businesses replacing high-hour rigs on a defined cycle may value a lease structure. Compare total cash cost, end-of-term obligations, early payoff, taxes, and ownership rather than monthly payment alone.

Finance the drill around profitable underground work

A directional drill should create or protect enough underground-construction margin to support the equipment payment without starving the crew of operating cash.

Before committing to the purchase, gather the complete equipment specifications, hours, seller proposal, tooling package, maintenance history, project backlog, existing debt, and realistic estimates of the rental expense, subcontracting cost, or additional capacity the drill will replace or create.
