Dedicated contact, short lines
For every project you get a dedicated contact in our office, with a direct line to the engineers running the calculations — fast response and short decision lines.
Geotechnics and foundation engineering
Stability and foundation engineering, tailored to your site.
VaCro-GSA designs retaining systems, pile foundations and slope stability for contractors, architects and developers across Belgium. Pragmatic, fast and in line with the applicable standards and guidelines.
Why VaCro-GSA 01 02 03 04
Fully Eurocode compliant
All calculation reports follow EN 1997-1 (Eurocode 7) with the Belgian National Annex. Ready for review and permits.
Indicative or full calculation
First a quick indicative sizing for tendering, then the definitive study. No surprises.
Practical site advice
Execution drawings, sections and — when needed — site visits. We think with the contractor.
Services
All services Our expertise
One logic: soil parameters, loads, deformations — and the right technique for your situation.
Soldier pile wall (Berlin wall)
Vertical steel soldier piles with timber, concrete or steel lagging between them.
Learn more
Pile wall (secant or tangent)
Continuous row of bored concrete piles — secant (temporary water cut-off) or tangent (above the water table).
Learn more
Soil-mix wall (CSM panels or columns)
In-situ soil-cement wall built up from panels (CSM) or overlapping columns.
Learn more
Diaphragm wall
Reinforced-concrete wall cast in the ground — permanent retention, water cut-off and bearing.
Learn more
VHP — jet grouting (Very High Pressure)
Soilcrete columns formed by jet grouting — used as a retaining wall or as a load-bearing pile, also under existing foundations.
Learn more
Sheet pile wall
Steel sheet piles for permanent or temporary earth retention and water cut-off.
Learn more
Underpinning by piers and shafts
Deepening existing foundations — masonry underpinning up to 1.2 m or shored shafts for greater depths.
Learn more
Pile foundations
Bored, driven, screw, displacement, grouted and micropile design to Eurocode 7.
Learn more
Slope stability
Stability analysis of new or existing slopes, embankments and excavations.
