Sustainable Products for Geotechnical WorksÂ-PPT Presentation

PPT Presentation

Pdf Summary

The presentation argues that sustainability in geotechnical construction is shaped largely during project planning. Although construction is necessary, early decisions about land use, materials, contractors, and design can significantly reduce environmental impacts.

Four approaches are highlighted:

- <strong>Geothermal activation:</strong> Geotechnical structures can also provide renewable heat. In a Füssen housing project, probes attached to steel beams in a Mixed-In-Place (MIP) retaining wall transferred heat from the ground. The system produced 5.5 kW of heat from 1 kW of electricity. Early involvement of geotechnical specialists made it possible to design the wall as a heat accumulator.
- <strong>Lower-carbon design and transport:</strong> For a Berlin project, a proposed diaphragm wall and jet-grouting solution was compared with a MIP wall and silicate gel grout plug. The alternative reduced estimated emissions from the geotechnical works by 55% and reduced truck movements to the site by 71%.
- <strong>Digitalization:</strong> Production dashboards can help engineers track progress, quality, and resource use. Timely data enables early identification of deviations and helps reduce waste and overconsumption.
- <strong>Partnership:</strong> Cooperation, trust, shared information, and continuous improvement can improve project quality and efficiency. Awarding decisions should recognize sustainable and effective solutions—not simply select the cheapest provider.

The central conclusion is that sustainable geotechnical construction is already achievable and represents a growing field. Early planning, innovative technical choices, digital tools, and collaborative project delivery can all contribute to a smaller carbon footprint.
