The major construction project, the Altona Cover (Deckel Altona), over the A7 federal motorway in Hamburg, sets new standards for urban integration and environmental protection. This 2.2-kilometer-long cut-and-cover tunnel structure, built north of the Elbe Tunnel, not only gains the city 190,000 m² of new public space but also delivers a significant increase in peace and improved air quality for residents. The ARGE Deckel Altona consortium (Implenia AG and Hochtief...

The Green Bunker in Hamburg-St. Pauli is a construction project of superlatives. But did you know that true quality often lies in the small, precise details? Watch the video to see how MARO concrete cones played a decisive role here! Their task: to invisibly seal hundreds of holes left by transport anchors in the new, green-coloured precast concrete elements. The challenge: colour fidelity and precision With green-coloured concrete, identical colour...

The Hochbrück Horb bridge is being built between Nordstetten and Rauschbart. The carriageway runs at a height of 70 metres – including the pylons, the bridge reaches a height of up to 90 metres. The B32 crosses the approximately 700-metre-wide valley on five huge bridge piers. Even such an impressive feat of engineering consists of countless details and small parts. We are delighted to have been able to make a...

Tie points and their closure are essential for high-quality exposed concrete. Tie points and their closure are essential for high-quality exposed concrete. This is well illustrated by the new headquarters of the project developer and building contractor weisenburger (sic!) in Karlsruhe. It had to be exposed concrete, and if it was to be exposed concrete, then it had to be by the exposed concrete architect Tadao Ando! The formwork joints...

We are happy to take part in a project like this, even with a simple part such as a concrete cone, because even avant-garde needs concrete cones. Berlin has a new architectural highlight! .     After a design by Rem Koolhaas, an avant-garde 3-point throw was created in the former newspaper district. The 300 million project began in October 2016. It is supposed to be more than just a...

Particularly exposed concrete architecture requires special detailed solutions. The concrete facade is soft-drawn with a structured surface. This is a nice contrast to the pointed edges. The dark anthracite of the concrete appears massive. This is addressed by the large, free intermediate levels. In order to ensure that the anchor points of the site-cast concrete components do not cause any disturbance in the defined sections, the color and surface of...

The details make the difference. A private construction site in Adelsried shows how important details are for harmonious exposed concrete. Clamping points are almost unavoidable in the construction of concrete walls. The anchors are used to span the formwork so that it can withstand the pressure of the concrete. This leaves round openings with a diameter of approx. 4 cm. In exposed concrete, these anchor points are also a characteristic...
