The ecological potential of geotextiles

Technical article, Applications, Coastal protection, Geosynthetics, Hydraulic engineering, Materials

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

The ecological performance of geosynthetics – opportunities and challenges in offshore applications

Technical article, Applications, Geosynthetics, Hydraulic engineering, Materials, Renewable Energy, Sand containers

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

Stiff geogrids over wet mortar columns – for soil improvement of a newly designed waterfront promenade and for load shielding of an existing quay wall

Technical article, Applications, Civil engineering, Coastal protection, Geogrids, Geosynthetics, Hydraulic engineering, Materials

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

Filtering with geosynthetics – an overview

Technical article, Applications, Civil engineering, Geosynthetics, geotextiles, Hydraulic engineering, Materials

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

Koserow Pier

Technical article, Hydraulic engineering

Heinz Büchner, b&o; Engineers 1. General information The pier in the seaside resort of Koserow, built in 1992, is currently closed from the 8th foundation pile onwards because its load-bearing capacity can no longer be guaranteed. The defective connection of the reinforced concrete cross beams to the steel piles at foundation piles 1 to 8

Geotechnical features in the construction of "eco-berms" on soft river sediments

Technical article, Applications, Geogrids, Geosynthetic Barriers, Geosynthetics, geotextiles, Hydraulic engineering, Materials

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
