Trunk sewer under I-15 corridor mixed-use fill
Deep gravity sewer with tight elevation tolerance — shaft footprints replace a continuous trench that would conflict with shallow Rocky Mountain Power and fiber.

Tunneling / TBM in Lehi, UT
Microtunneling and pipe jacking for Lehi municipal trunk sewers — sealed-face mining when HDD diameter or grade tolerance cannot meet Utah County gravity specs along Utah Lake fringe.
Tunneling / TBM in Lehi, Utah
Tunneling and TBM work in Lehi targets municipal trunk sewers, large outfalls, and owner specs where steerable HDD cannot hold gravity grade or diameter. Shaft spreads localize disruption compared to open trenching a deep urban trunk through utility-congested fill along I-15 corridor and SR-92.
Utah Lake fringe and Thanksgiving Point outfall projects often land here — high groundwater, floodplain review, and settlement limits push engineers toward pipe jacking instead of wide open cuts through mixed-use blocks and riparian ROW near Silicon Slopes.
Residential laterals and short commercial shots stay on HDD or auger bore. Microtunneling in Lehi is a municipal and large-contractor tool — we scope shafts, slurry handling, and Utah County inspection milestones when your plans call for it.

Local Tunneling / TBM Scenarios
Real Utah County angles — not generic statewide copy.
Large outfall toward Utah Lake fringe
Floodplain and bank stability rules favor bored installation over stripping fringe ROW. Shaft design accounts for seasonal high water and I-15 adjacency.
Deep collector near Silicon Slopes tech campus
Tech campus districts combine shallow telecom, chilled water, and gas with deep sanitary collectors. TBM reduces surface disruption across customer-access drives.
UDOT large-span alternative on I-15 corridor
When HDD profile cannot meet large RCP grade on a state crossing, microtunneling may be specified — shafts, spoils export, and MOT are engineered upfront.
How Tunneling / TBM Works in Lehi
Lehi TBM and microtunnel scopes begin with shaft design, geotech, and permit path — Lehi City, Utah County, UDOT, and Utah Lake fringe floodplain where applicable. Laser-guided line and grade drives the mining face; slurry or spoil handling is planned for urban sites with limited laydown near the I-15 corridor. Inspection hold points follow municipal or owner spec before carriers are accepted.
Soil & Geology — Utah County
North Utah County bench clay, Dry Creek alluvium, and compacted fill on Silicon Slopes tech-campus pads — cobble toward Traverse Mountain.
Lehi bores encounter bench clay on most residential grids, Dry Creek alluvium on east-side alignments, and cobble toward Traverse Mountain. Tech-campus fill over native clay adds compaction variables. Silicon Slopes trunk bores at depth may hit cobble lenses without proper bit selection.
Weather & Scheduling
Utah County bench winds and tech-campus dust push Lehi crews to plan mud programs for bench clay and TI-schedule windows around Silicon Slopes construction traffic.
Tech-campus construction traffic influences staging windows on corridor jobs. Spring Dry Creek runoff raises groundwater on east-side alignments. Summer heat on exposed campus pads affects crew safety — we plan seasonal windows with TI deadlines.
811 Locates & Permits in Lehi
Lehi City Engineering, Utah County ROW, UDOT I-15 Silicon Slopes relocations, and Dry Creek floodplain on east-side alignments.
Lehi City Engineering handles street and ROW permits. Utah County ROW applies on outer edges toward Saratoga Springs. UDOT controls I-15 Silicon Slopes corridor bores — expect MOT and tight schedule windows. Dry Creek floodplain work may need additional review.
Trenchless vs Open-Cut Here
Open trenching a deep trunk through I-15 corridor or Utah Lake fringe ROW destroys more surface infrastructure than shaft-and-drive tunneling. HDD still wins on shallow laterals; TBM applies when diameter, grade, or length exceed practical steerable limits.

How we work
Our Process for Lehi Tunneling / TBM
Scope & Site Walk
You share plans or describe the problem; we confirm alignment, depth, access, and which trenchless method fits Utah soils.
811 Ticket & Marks
Blue Stakes 811 ticket filed; wait period before pits open unless your permit path differs. We pothole where marks conflict.
Profile & Permits
Bore plan, UDOT or city ROW permits, railroad agreements, and crossing engineering when the path leaves private property.
Rig Mobilization
Compact spread for tight Millcreek lots; larger HDD for I-15 or I-80 relocations — matched to length and diameter.
Pilot & Ream
Steered pilot on design line, ream passes sized for your pipe or casing, fluid program tuned for clay or sandstone.
Pullback & Install
HDPE fusion, steel casing, or multi-duct bundle pulled with tension and bend-radius monitoring.
Test & As-Built
Pressure test, mandrel, or survey records for owners, inspectors, and operators as spec requires.
Restore & Closeout
Compact pits, replace sod or hardscape per scope, leave Blue Stakes ticket and locate map in your project file.
FAQ
Tunneling / TBM in Lehi — FAQ
When does Lehi need TBM instead of HDD?
Large-diameter gravity sewer, tight grade tolerance, or owner spec for sealed-face mining. We review your engineer's method note and geotech before quoting.
How long do Lehi microtunnel projects take?
Shaft construction and permitting often exceed mining duration. Utah Lake fringe floodplain and I-15 adjacency add calendar weeks — scoped in the estimate.
Is microtunneling common for Lehi residential?
Rare — laterals and short commercial runs stay on HDD. TBM applies to municipal trunk, large outfalls, and engineered deep gravity lines.
What permits apply to TBM in Lehi?
City, Utah County, UDOT, and Utah Lake fringe floodplain depending on alignment. Permit path is scoped before shaft design.
Can TBM work in Lehi Utah Lake fringe clay?
Yes with proper face support and groundwater handling. Geotech and dewatering plans are engineered before mining starts.
