We have all seen Lego bricks: interlocking because of the holes in the bottom and the studs on top. Jansen B.V. produces such bricks in a heavier and larger size. Stackable concrete blocks, made of concrete that was recycled in our own company.

Legioblocks can be easily stacked without the use of cement or fasteners and is ideally suited for retaining walls, storage bays, partition walls, silage pits, salt storage and industrial buildings.

With over 30 years of experience and the production and supply of more than 2,500,000 blocks in Western Europe, the USA and Asia, we can rightly call ourselves specialist as well as market leader. And we’re proud of that! We use all our knowledge and experience for your project. From building a simple wall to the delivery of complete logistics halls with sliding roofs.



Quality is an important pillar of A. Jansen B.V’s policy and work. It forms the basis for long-term cooperation and is essential to the continuity of the company. A. Jansen B.V. strives for a high quality awareness in all areas of the organization.
