Renaturation of the Alpenbach

In the Mühlheim an der Ruhr region, Van Boekel GmbH is working on a natural engineering project, returning the Alphenbach back to its natural state by renovating the estuary of the Alpenbach an der Ruhr.  We installed a new culvert with a natural stone runout to the Ruhr river. Furthermore, we restored a 350-metre section of the Alpenbach to its natural state.

  • Stadt Mühlheim an der Ruhr

Restoring nature’s old form

The work consisted of:

  • Groundworks
  • Removing trees and shrubs that no longer fit into the landscape
  • Plants (planting and transplanting young pollard willows)
  • Sowing
  • Removing 2 culverts (1 brick culvert, 1 concrete culvert)
  • Construction of 2 new stream passages, 1 made of prefabricated steel and 1 made of reinforced concrete, each with the delivery of static calculations and drawings.
  • Delivery and installation of railings at the stream passages
  • Delivery and installation of paving

The natural engineering work was carried out on fallow land.

The first Alpenbach passage is located just a few metres away from the estuary of the Ruhr. The second passage is about 240 metres upstream and provides access to the adjacent areas, which are currently used for agriculture.

How can we help?

Van Boekel Bouw & Infra changed its course a few years ago, shifting our focus to multidisciplinary concrete projects in the civil and non-residential construction sectors. We started to emphasise Best Value Procurement (BVP) projects, which enabled us to escape the low-cost market. This change of course has netted Van Boekel Bouw & Infra new clients, whilst enabling us to specialise in new types of projects and contracts, such as UAV-gc, and expanding our work area in the Netherlands and abroad.  Our organisation and employees worked hard to make this transition into a success, focusing on acquiring new clients and completing new projects.
