One call does it all

Infiltration testing
with preliminary rates
before we leave the site.

Stormwater infiltration testing across Pennsylvania, run to PA DEP's manual. We bring the machine, the operator, the water and the crew, and we can run up to 50 tests in a day.

Rates before we leave

You don't wait weeks to know what the ground will do.

Every reading is timed and GPS-located through our proprietary digital field system. Preliminary rates go to you and your engineer the same day, so the design can shift while the machine and crew are still on site.

Same-day rates

Numbers the day we test, not weeks later.

Shift the design on site

Move to better ground under the same mobilization.

One record

Every pit tracked from layout through the bound report.

We report the measured rate for every pit. Grouping, factor of safety and the sealed design rate stay with your engineer of record. You get the raw interval data behind every number, not a summary.

What we do

Testing for every stage of the basin.

For the engineers, developers, contractors and townships who need to know what the ground under a site will actually take.

Before you close

Due diligence screening

Test ground you have not bought yet. Two to four pits in the likely basin footprints, inside your contingency window, on an access agreement. The cheapest test you will ever buy is the one that lets you walk away.

Before layout

Site screening

Test across the property before the layout is set, evenly distributed the way the state expects, so basins land where the soil actually works.

At design elevation

Basin and trench testing

Tests set within a vertical foot of the bottom elevation you intend to build, with the pit carried two feet deeper so any limiting zone under the floor is found and logged instead of assumed.

After construction

Construction confirmation

Retest the finished surface once it is cut to grade. Under the draft PCSM manual this is expected on facilities converted from an E&S trap or basin, and the result has to come back at no less than 80 percent of design.

Logging the soil profile, layer by layer, from grade down.

Excavator-cut subsoil face at depth in a test pit — The cut face at depth, where the rate gets measured.

What a pit actually looks like

Dug to elevation, then two feet past it.

The test goes within a foot of your proposed bottom. The pit keeps going, so what sits under the floor is confirmed rather than presumed.

An open test pit with water standing at the floor and soil horizons visible in the pit wall — A test pit carried below the proposed basin bottom. Standing water at the floor is the kind of limiting zone the design has to account for.

Section through a test pit. Soil horizons are logged layer by layer from existing grade to the bottom of the pit.

Two ways to run it

Hand us the whole thing, or just the parts you want.

No coordinating a surveyor to stake, a crew to dig and a tester separately. One vendor, one invoice.

Scoping and schedule

How many tests, and how fast.

Send a plan or an address. You get a proposal back in a day or two, with the test count and the basis in writing, so you can put a line item in your own proposal.

Test countPlaced to the PA DEP minimum for each facility, under the PCSM method.

Crew capacityUp to 50 tests in a day, so large multi-basin and campus sites go in one mobilization; larger programs over consecutive days.

ProposalBack to you within a day or two of your request.

MobilizationTypically within two weeks of go-ahead.

Preliminary ratesEmailed the day we test.

Bound reportTypically within 48 hours of completing field work.

How it works

Three steps, one mobilization.

Call us

Send a plan or an address. You get the test count, the schedule and the cost.

We show up

Machine, operator and crew arrive together. Every test runs until the rate stabilizes, with the temperature recorded at each reading.

You get the rates

The measured rate for every pit, emailed the same day. The bound report follows, typically within 48 hours of completing field work.

What you get

The report is the proof.

Per-pit data sheet

Every reading, timed and located, for each test pit. Raw interval data, not a summary, available as a spreadsheet (CSV or Excel) that drops into the DEP PCSM spreadsheet.

Soil log

Layer by layer from existing grade down through the limiting zone check.

Location map

GPS coordinates, NAD83 Pennsylvania State Plane (zone per site), for reference. Not a boundary or control survey.

Measured rates

A measured rate for every pit, built for your PE's review and seal. Sealing available if you would rather we arrange it.

Sample same-day preliminary field result sheet

Sample infiltration report, summary of results page

Sample infiltration report, per-pit timed interval data sheet at stabilization

Sample infiltration report, soil log page

The same-day preliminary field result, and pages from the bound report that follows. Every project and client identifier is redacted.

Who we are

Run by the people doing the work.

FIG works out of the Pittsburgh area, run by people who have spent their careers in heavy civil site development. The engineering side brings thirty years of estimating, planning, design and construction on sites across Pennsylvania, from residential subdivisions and commercial pads to energy and data-center campuses. That is thirty years spent on exactly what an infiltration rate does to a stormwater design and a budget, now on your side of the test pit.

The field side came up around farm and construction equipment, so the machine, the crew and the testing are all in-house. When you call, you reach the people doing the work. No account manager, no hand-offs, no layers between you and the crew in the ground.
