Geotechnics

Geotechnics

Geotechnical engineering is a key competence at SBE and an essential part of almost every project. The field of geotechnics has a wide scope, ranging from foundation design of retaining walls and bridges to the design of embankments and the stability of excavations.

Foundation design

Sand, clay, rock, swamp; all these kind of soils require a different geotechnical approach. The foundation of a bridge on soft clay will usually require a piled foundation with piles reaching to a load-bearing layer (eg. dense sand). Conversely, for the same bridge on a dense, sandy soil, a limited piled or even a shallow foundation will be sufficient. An other example are quay walls; many types exist in function of the soil conditions and the retaining height and load conditions.

SBE has an experienced team of geotechnical engineers who are capable of designing geotechnical solutions for even the most complex projects. We have made designs for on-, near- and offshore structures across the globe in very varying conditions which enables us to deliver high-end solutions for any challenge.

Earth works

During the works, a construction site must remain stable and free of (ground) water at all time without impacting the surrounding infrastructure and without disturbing the people living around the site. Slope stability during construction and ground water control are key elements in many engineering projects.

Earth works

SBE is renowned for its lock and quay wall engineering. Massive construction sites measuring several hundreds of meters in length and more than 30 meters deep are typical challenges we are faced with on a regular basis. We also have broad experience with the excavation of car parks and stability of (underwater) slopes.

Embankment design

Integrated river basin management has a wide scope; one aspect is the preservation of natural river banks and spawning areas. Many river systems have to cope with varying discharges in monsoon and dry season. Other rivers are exposed to tides. In both cases, as a result of heavy rainfall, river banks can be seriously eroded and endanger ecological systems and people living nearby.

Embankment design

A sound geotechnical design of the enbankments in combination with proper vegetation management are a classic solution for these issues. Belgium has an extensive river network and SBE has designed many ecological river embankments along the River Scheldt and its tributaries. We shared our knowledge for other projects in Cambodia, Vietnam, Congo, Myanmar and other countries.
