Soft ground conditions can have a significant impact on project risk, constructability, programme and long-term asset performance.
FSG provides specialist geotechnical expertise to identify, assess and manage these risks through detailed site characterisation, advanced analysis and practical engineering solutions. Our team combines a thorough understanding of soft soil behaviour with extensive construction experience to develop ground models that accurately reflect site conditions and support informed project decisions.
From early feasibility studies through to detailed design and construction support, we help clients understand the implications of soft ground on the design and performance of foundations, earthworks, embankments, pavements and infrastructure assets. By integrating investigation, analysis and construction considerations, we develop ground improvement strategies that are technically robust, commercially practical and tailored to project performance requirements.
Understanding the ground from the outset.
Successful ground improvement begins with a clear understanding of the subsurface conditions and their implications. FSG undertakes targeted geotechnical investigations, laboratory testing and interpretive assessments to accurately evaluate the strength, compressibility, settlement characteristics and variability of soft soils across a site.
Our focus is on developing reliable and realistic ground models that allow project teams to understand the risks, opportunities and likely performance of the ground before selecting a treatment approach and extent. By identifying key geotechnical consideration in the early stages, we help clients make informed decisions regarding project feasibility, design optioneering, construction staging, ground improvement options and delivery requirements, reducing uncertainty and avoiding unnecessary treatment costs.
Ground improvement design and specification.
FSG designs and specifies ground improvement solutions that balance technical performance, constructability and project economics. Our experience includes rigid inclusions, stone and sand columns, dynamic compaction, dynamic replacement, soil mixing, surcharge treatment and other specialist ground improvement techniques.
We combine advanced geotechnical analysis with practical delivery experience to determine the most appropriate treatment methodology, treatment extent and performance criteria for each project. Our services extend beyond design to include specification, construction support, monitoring, performance verification and quality assurance, ensuring the ground improvement works achieve the required outcomes in practice.
This integrated approach provides clients with confidence that treatment solutions are not only technically sound, but offer value for money, can be delivered efficiently and perform reliably over their service life.
