    The building blocks of your project

High-quality prefab elements

The general public knows the Willy Naessens Group mainly for its Industrial Construction, Agro & Swimming Pools departments. Alongside these units, the Willy Naessens group also has a number of major prefab concrete plants.

These plants manufacture a wide range of prefab elements such as slabs, support structures, bridge deck overlays, industrial wall elements, stairs and lift shafts. This branch of the Willy Naessens Group also includes the steel production plant of Gebroeders Snoeck.

Quality labels for guaranteed results

The philosophy of the Willy Naessens Group is to strive for the best quality, both for industrial construction and for the concrete elements manufactured in the production plants. This has enabled a number of plants to be awarded the BENOR and KOMO quality labels.

Altaan Dilsen-Stokkem

Altaan Dilsen-Stokkem40

Founded in December 1989, Altaan specialises in the production of prefab concrete elements for industrial and residential buildings, shopping malls, office buildings and high-rise buildings. The product line consists of columns, beams, heavily reinforced shell wall elements and stairs in prefab concrete. The company also profiles itself as a supplier of prefab reinforcement cages and has its own design office.

Altaan joined the Willy Naessens Group in 2012. This takeover fits in with the further demerger of the group’s activities in Limburg: the supply of these Limburg sites can now fully rely on the local sourcing of both structural, concrete and wall elements, which benefits transport costs and therefore also the construction costs. Furthermore, Altaan is ideally situated for exports to the Netherlands and Germany.

Concreton Geraardsbergen

8_concreton

Concreton has been operating from Geraardsbergen since 2000. The product line consists mainly of columns and beams in reinforced and prestressed concrete, including the production of round columns in the most diverse forms. In addition, Concreton specialises in working with higher strength classes of prefab concrete.

Such advanced specialisation means that you can safely entrust us with your complex construction projects. Concreton holds the KIWA quality label for supplies on the Dutch market and the NF label for the French market.

Seveton Oudenaarde

11_seveton

Seveton was founded by the Willy Naessens Group in 1997. The company is split up into two production units.

One unit produces prestressed concrete roof elements. With their stability and self-supporting properties (length of up to 13 m), large spans can be achieved without any extra support structure being required. Standardisation and automation allow for an enormous annual production capacity of 350,000 m²

The second unit produces concrete wall elements in smooth concrete or washed concrete with various colours or concrete on structure mats. The concrete panels can contain a cold bridge-free insulation core that is up to 14 cm thick.

Due to their stability, large dimensions, ease of installation, good fire resistance and insulating capacities, these elements find application in various industrial construction projects in the Benelux and France.

Structo Brugge

Structo was founded in 1948 and is based in Bruges. The company was taken over by the Willy Naessens Group at the end of 2016. Structo specialises in the production of prestressed prefab concrete elements: hollow core slabs in prestressed concrete for industrial, utility and housing construction projects, and the production of beams and columns in prestressed concrete for industrial and civil engineering applications up to 45m in length.

To this end, Structo has a very large production capacity and also operates under various quality labels:   Komo, Benor and NF. In addition, Structo has extensive experience and a solid reputation in the production of prestressed bridge overlays for civil engineering projects.

As the only West Flanders concrete prefab plant of the Willy Naessens Group, the Bruges-based Structo is ideally located to supply West Flanders and France. Moreover, its product range is compatible with that of the other prefab concrete units within the Willy Naessens Group, so that both prestressed beams and prestressed hollow core slabs are sold on the Belgian, Luxembourg and Dutch markets.

Willy Naessens Construct Oudenaarde

13_construct

To meet growing demand and ensure compliance with increasingly stringent requirements imposed by clients, authorities and architects, the Willy Naessens Group decided in 2007 to start up a new production unit for the prefabrication of wall elements.

This new plant pushes the boundaries of conventional wall production: a theoretical capacity of 1800 m²/day, wall elements up to 4 m high (floor heights), wall elements up to 12 m long, and well elements weighing up to 32 tonnes.

An ingenious concept allows this unit to produce a varied range of elements: industrial wall elements, walls for offices, supporting wall elements, grey concrete shells. In addition, a state-of-the-art mixing unit ensures the unlimited supply of constant mixtures, whether coloured or not.

To enable the supply of raw materials by ship, the unit was erected on the banks of the Scheldt. Power is supplied by solar energy, and an extensive water recycling installation obviates the need for an external water supply.
