Sewer lateral under Willow Creek driveway
Root-intruded PVC — static burst, mature front yard and concrete preserved.

Tunneling / TBM in Centennial, CO
Pipe bursting in Centennial for sewer and water lateral replacement in Willow Creek, Foxridge, and Hunters Hill — no open trench through expansive clay front yards.
Tunneling / TBM in Centennial, Colorado
Pipe bursting in Centennial restores sewer and water laterals in Willow Creek, Foxridge, and Piney Creek without disturbing established yards and mature landscaping. Static bursting frags host pipe and pulls HDPE replacement through Arapahoe County expansive clay — one entry and one exit pit replace a continuous trench through landscaping that decades-old neighborhoods carefully maintain.
Centennial's PVC sewer stock from 1980s–2000s subdivision builds carries root intrusion and offset joint failures confirmed by CCTV. Bursting handles these in-place rather than full pavement removal.
Expansive clay seasonal behavior affects burst-head friction — dry summer clay may require hydration pre-treatment for consistent advance.

Local Tunneling / TBM Scenarios
Real Arapahoe County angles — not generic statewide copy.
Water service under Foxridge approach
Corroded service under concrete — burst in-place with HDPE, driveway intact.
Sewer main renewal in Piney Creek cul-de-sac
Camera-confirmed offset joints — burst through clay host with HDPE replacement.
Water lateral under Hunters Hill lot
Failing water service under established landscaping — burst and pull HDPE, yard stays.
How Tunneling / TBM Works in Centennial
Centennial burst crews CCTV-confirm host condition, seasonal clay moisture assessment, and pull 811-cleared locates before expander enters pipe. Expansive clay friction is predictable when properly hydrated. Post-burst CCTV confirms pipe seat.
Soil & Geology — Arapahoe County
Arapahoe County expansive clay, sandy alluvium near Dry Creek and Cherry Creek, and compacted fill on E-470 corridor developments.
Centennial bores hit expansive clay on most residential grids, sandy alluvium near Dry Creek, and compacted E-470 corridor fill over native clay. South-metro clay behavior differs from north metro — shrink-swell cycles affect mud weight and pit shoring on summer jobs.
Weather & Scheduling
Eastern Arapahoe plains hail and summer heat push Centennial crews to plan lightning holds on exposed south-metro retail pads.
Summer heat and afternoon lightning affect exposed south-metro retail pads. Dry Creek spring runoff raises groundwater on south alignments. We communicate seasonal windows with your project schedule.
811 Locates & Permits in Centennial
City of Centennial Public Works, Arapahoe County ROW, CDOT I-25 south and E-470 relocations, Dry Creek floodplain adjacency.
City of Centennial handles permits inside city limits; Arapahoe County ROW applies on outer edges. CDOT I-25 and E-470 authority control state corridor bores. Dry Creek floodplain adjacency may add review on south alignments.
Trenchless vs Open-Cut Here
Open-cut through Willow Creek and Foxridge established yards adds months of expansive clay restoration — bursting trades that for two pits.

How we work
Our Process for Centennial Tunneling / TBM
Scope & Site Walk
You share plans or describe the problem; we confirm alignment, depth, access, and which trenchless method fits Colorado soils.
811 Ticket & Marks
Colorado 811 ticket filed; wait period before pits open unless your permit path differs. We pothole where marks conflict.
Profile & Permits
Bore plan, CDOT or city ROW permits, railroad agreements, and crossing engineering when the path leaves private property.
Rig Mobilization
Compact spread for tight Boulder lots; larger HDD for I-25 or I-70 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 811 ticket and locate map in your project file.
