1. Background The demand for raw materials continues to grow unabated, and efforts to decouple economic performance from resource consumption have so far been largely unsuccessful. According to estimates, global raw material consumption will at least double over the next 30 years (1). The construction sector plays a very important role in terms of efficient […]

Geotextile materials are increasingly being used in coastal protection as an alternative to natural stone, slag and concrete. In this environment, geotextiles, like all technical surfaces, are colonised by organisms, a phenomenon commonly referred to as biofouling. In a two-year experiment, the colonisation of benthic organisms on two different geotextile materials (woven and non-woven) was

Introduction The construction industry is of great global importance in achieving sustainable development goals. It accounts for around 50 per cent of the resources used globally, 30-40 per cent of energy demand, 20-40 per cent of greenhouse gas emissions and around 17 per cent of fresh water consumption. On the other hand, all players in
1. Summary The following article describes the redesign of an existing harbour promenade in the Lower Elbe area in order to increase the attractiveness of the harbour area, open up the former exclusively commercial harbour area and integrate the harbour into city life. This requires raising the ground level. Due to the low-bearing soil layers
Introduction Geotextiles used as filters must be dimensioned in such a way that the soil to be filtered is protected from erosion, the load-bearing grain structure is kept stable, the passage of fine grains is only permitted to a non-critical extent so that clogging – the accumulation of fine material on the filter – is

Introduction Many dam walls at river power stations were built several decades ago and now need to be upgraded and raised due to increased flood protection requirements. Dam walls are usually raised by widening them on the air side, which in many cases requires a comparatively large amount of land and encroachment on the air-side

Two practical examples are used to explain waterproofing with plastic sealing membranes and the use of geosynthetics. The new section of the A 72 motorway south of Leipzig runs over challenging subsoil with problematic geology. The area is a landscape left behind by lignite mining in the 20th century – surrounded by partially filled former
Introduction At the end of the 1980s, a new landfill site was needed in the district of Bad Kissingen, as the Arnshausen landfill site that had been in operation until then was almost completely filled. A quarry in the immediate vicinity of the old landfill site, where shell limestone had been mined for gravel since
Introduction Tailings dams are mining waste dumps where the products of mineral extraction are deposited. These residues consist of fine-grained material and are usually deposited hydraulically. In principle, these processing residues can be generated in the energy sector (e.g. ash) or in the mineral extraction industry (gold). Neglected for decades, the industry's attitude towards tailings

1. Scope and principles The guideline "836.4107 Construction in water protection areas" is a continuation of the previously applicable regulation "836.0509 Water protection and soil protection". The new guideline takes into account the advancing state of the art and the further developed legal basis. Thematically, this guideline is related to guideline "836 Planning, constructing and

Project overview The Stuttgart–Ulm rail project consists of the Stuttgart 21 sub-project and the new line from Wendlingen to Ulm. Stuttgart 21 refers to the complete reorganisation of the Stuttgart rail hub, with the new underground station at its heart and the line to Stuttgart Airport and Wendlingen. The subsequent new line will enable high-speed
GEG Limited Liability Company Landfill I: The oldest section of what later became the "Halle-Künsebeck Central Landfill" was filled with domestic and commercial waste from 1966 to 1982. The Halle-Künsebeck I and II landfills are located in quarried limestone pits on the southern ridge of the Teutoburg Forest. To the north, east and west, the
