Pile dynamic load testing

High strain dynamic load testing is a cutting-edge pile testing technique which offers the same result as a static load test for a fraction of the time and cost.

The test result, a load-bearing curve per tested pile, allows the contractor to assess the performance of the pile.

Thanks to our team's experience, Fondytest offers efficient, reliable, and cost-effective dynamic load tests.

Our expertise

Using our state-of-the art loading device and our in-house expertise, we can guide you towards a successful pile testing campaign. Our technology is the result of a 20-year research program combined with our team's 30 years of experience.

The test not only produces a load-bearing graph but also gives the base resistance vs shaft friction distribution and a clear picture of the pile integrity.

Fondytest's dynamic load testing service is


Depending on the site conditions, our team can perform up to 8 dynamic load tests per day. Compare that to the 3 days it takes to perform only 1 static load test.


Fondytest is a spin-off company of the Université catholique de Louvain and its founders have years of experience in dynamic load testing.


You get more results than a static load test for a fraction of the cost.

Dynamic load testing is the core business of Fondytest. Over the years, we have successfully tested




of various type

  • Bored,
  • Screw,
  • Precast driven,
  • Driven cast-in-place,
  • CFA...

with diameters ranging from

0.4 to 1.3 m

lengths varying from

9 to 35 m

and reaching equivalent static loads of

0.4 to 36 MN

The test is standardised by the XP P 94-152, ISO 22477-4, and ASTM D4945 standards. A dynamic load test is also called a PDA test or a DLT.


Furthermore, our operators have at least passed the Advanced level of the Pile Driving Contractors Association's PDA Proficiency test.

We are based in Belgium and also available in the neighbouring countries: the Netherlands, Luxembourg, and France. Moreover, we regularly perform dynamic load tests in Eastern and Southern Africa.
