Professionals with decades of worldwide experience

Who are we?

Allnamics is a global company with experts in the field of geology, soil mechanics, geoscience and foundation engineering. These experts apply local geotechnical knowledge and experience to perform foundation engineering, soil mechanics and pile testing.

Allnamics can act as consultant or perform pile testing and geotechnical monitoring as service, both onshore and offshore. Allnamics develops and sells advanced methods for drivability studies, pile monitoring during installation, pile testing and assessment of existing foundation structures.


Whether as a supplier of hardware and software for foundation testing and pile driving simulation or as a reliable advisor in these areas, Allnamics’ activities are founded on 50 years of experience with foundation piles, impact driven as well as vibro driven, onshore as well as offshore.

During those years our staff was intimately involved in the development of multiple testing methods, such as low strain dynamic testing, high strain dynamic testing, and Rapid Load Testing.

With these capabilities, Allnamics is ready to support the installation of deep foundations around the world.

Allnamics Academy: training on site


The history of Allnamics goes back to the 1970s when oil was discovered in the North Sea. When massive structures were built and placed on the sea bed, the need arose to check the foundations. At this time, Peter Middendorp and Marcel Bielefeld, both working for the Dutch TNO Building and Construction Research Institute, laid the foundation of nowadays Allnamics.

Allnamics was founded in 2011 by five experienced engineers in pile testing, foundation engineering, geotechnical monitoring, and soil mechanics. This team continues to increase in size as Allnamics expands its operations.

The in-house developed products like the StatRapid, Reyca, PDR, and other advanced monitoring equipment are sold and delivered worldwide. With extensive experience and knowledge of all types of pile testing techniques, the ever expanding team of highly educated, yet practical experts of Allnamics is ready to support and assist all its clients around the world.


Allnamics works from various offices worldwide: in The Netherlands (both in The Hague and Amsterdam), Singapore, the USA, Spain, and the Caribbean. In addition, Allnamics is cooperating with agents and representatives in many other countries in geology, geotechnics, soil mechanics, foundation engineering, and pile testing.
