Pile Integrity Test
Pile Integrity Test
Before you begin construction, it’s essential to know what’s going on beneath the surface. Eurofins Spectro offers fast, reliable, and non-destructive Pile Integrity Testing (PIT) to ensure your concrete piles are free from hidden flaws like cracks, voids, or weak sections.
Whether you’re working on a new project or checking existing structures like bridges and towers, our PIT service gives you the confidence to move forward—safely and efficiently.
What is Pile Integrity Testing?
Pile Integrity Testing uses Low Strain Dynamic Testing (LSDT) to evaluate the soundness, length, and continuity of concrete piles. It’s a quick and cost-effective way to detect:
- Major cracks
- Voids or soil inclusions
- Changes in pile diameter
- Pile depth (approximate length)
Our method is based on the ASTM D5882-07 standard, widely accepted across the globe.
How the Test Works
- A small, lightweight hammer taps the top of the pile.
- Motion sensors (accelerometers) capture the reflected waves.
- Our advanced software (PIT-W) analyses the wave patterns.
- You receive a detailed report highlighting any irregularities.
Best part? The test is quick enough to evaluate every pile at your site if needed.
Where PIT is Used
- New construction sites
- Structural upgrades or repairs
- Bridge and tower foundations
- Large infrastructure projects
- QA/QC during piling operations

Before We Begin: Site Preparation
To get accurate results, the pile head must be:
- Clean and flat
- Free from debris, laitance, or bentonite
- Properly prepared (this step is crucial!)
A poorly prepared pile head can lead to misleading results, so we’ll guide your team on how to get it right.
Things to Keep in Mind
Like every method, PIT has its limitations:
- It doesn’t measure load-bearing capacity
- It offers limited insights into concrete quality
- Length estimates may vary slightly (approx. ±10%) due to variable wave velocity in concrete
Still, PIT is a powerful screening tool—especially when combined with structural records or further testing.
Frequently Asked Questions (FAQs)
Can all piles be tested using PIT?
Yes! PIT works for cast-in-place piles, precast concrete piles, and drilled shafts—ideal for both new and existing foundations.
How long does testing take?
We can typically test 30–50 piles per day, depending on site conditions and pile accessibility.
Is the test completely safe for the pile?
Absolutely. PIT is a non-invasive test that uses a gentle tap with a hand-held hammer—no damage whatsoever.
What should be done before the test?
Make sure the pile head is clean, dry, and flat. We’ll guide you through any necessary preparations to ensure accuracy.
Why should I trust Eurofins Spectro for PIT?
We’re backed by NABL accreditations and BIS approval , a nationwide lab network, and decades of expertise in foundation testing. You’ll get fast, reliable results from one of the most trusted names in testing.
