Woltman was founded in 1989 by Jaap Woltman, and since 2016, Woltman has been part of Dieseko Group. The piling and drilling rigs are a popular product due to their very high quality, as well as the good image the Netherlands has abroad.
Dutch customers are demanding and critical. They have increasingly raised the bar, because construction times are short and the hourly rate is high. The Woltman foundation machines perform excellently. Durable, reliable, easy to maintain and, above all, very stable and robust.
The Woltman piling rigs have very high mobility due to their foldable leader, and can be equipped with a wide variety of attachments for traditional pile driving with impact hammers. The multi-purpose rigs are also suitable for installing tubular piles or sheet piles with a vibratory hammer, resonator or a ring vibrator. For ground improvement operations, the rigs are able to perform vibroflotation or rigid inclusions. The PDS-type rigs with suspended leader provide the perfect solution for nearshore projects where pile driving and heavy lifting are combined.
