Ground penetrating radar

GPR in St. Louis scans for non-conductive pipe, voids, and unknown subsurface features when electromagnetic locating is not enough — on parking lots, yards, and unpaved sites throughout St. Louis.

Utility mapping & as-builts

Utility mapping in St. Louis turns field marks into CAD or GIS so Missouri GCs and owners keep a record instead of re-locating the same site from scratch.

Concrete scanning

Concrete scanning in St. Louis maps rebar, conduit, and post-tension cable before core drilling or saw cutting so St. Louis interior and structural crews can cut with a clear window.

Damage prevention programs

Damage prevention in St. Louis combines 811 ticket review, private locates, and documented marks so multi-site owners get one standard across St. Louis instead of surprise strikes.

How we work

A five-stage delivery process

Predictable execution from first ticket review to documented closeout — at every stage.

  1. 01

    Ticket & site review

    We review the 811 ticket, as-builts, and access, then walk the property to confirm what public marks miss before quoting.

  2. 02

    Scope & proposal

    You receive a written scope with methods, coverage area, deliverables, and pricing — typically within 48 hours.

  3. 03

    Field locating

    Crews apply EM, GPR, and concrete scanning as specified and paint APWA color-coded marks on the ground.

  4. 04

    Mapping & records

    Marks are documented with photos, sketches, or CAD/GIS mapping so the next crew is not starting from zero.

  5. 05

    Closeout

    You receive locate records, maps, and a documented closeout your superintendent can file with the job.

FAQ

St. Louis locating questions

Who is a licensed utility locating company in St. Louis?

Pinnacle Utility Locating is a licensed and insured private utility locating company serving St. Louis. Local crews handle electromagnetic locating, GPR, mapping, concrete scanning, and damage prevention to the same national standards we use in every market.

Do you locate private utilities that 811 does not mark in St. Louis?

Yes. Our St. Louis crews locate privately owned electric, water, comms, irrigation, and process lines on the customer side of the meter — the lines public one-call tickets leave unmarked.

Do you offer GPR and concrete scanning in St. Louis, MO?

Yes. We provide ground penetrating radar, concrete scanning, and utility mapping throughout St. Louis. Methods are written into the proposal so they match soil, surface, and the utilities on site.

Do you map locates for the next crew in St. Louis?

Yes. After we mark the ground, we can document findings with photos, sketches, or CAD/GIS so St. Louis GCs and owners keep a record instead of starting over on the next visit.

Do you serve areas outside St. Louis?

Yes. Our St. Louis crews cover St. Louis and surrounding communities throughout the Missouri metro. For properties farther out, we confirm coverage during the site review.

How soon can you assess a property in St. Louis?

Most St. Louis site reviews are scheduled within a few business days, with a written locating proposal typically delivered within 48 hours of the walkthrough.

How quickly can you provide a proposal?

Most commercial proposals are delivered within 48 hours of the site review. Multi-site or mapping programs may take slightly longer because each location is scoped for access, methods, and deliverables individually.

Do you locate utilities that 811 does not mark?

Yes. Public one-call marks the utilities that member companies own. Privately owned electric, water, comms, irrigation, and process lines on the customer side of the meter are our primary work — and the lines most often hit.

Are you licensed, insured, and able to meet vendor requirements?

Our crews carry general liability and workers' compensation coverage in the markets where they operate, and we regularly complete vendor onboarding, insurance certificates, and safety documentation for GCs, industrials, and property managers.
