ABSTRACT
Geosynthetic solutions offer sustainable alternatives, delivering long-lasting, stable embankment foundations that are easier and faster to build compared to traditional methods, reducing not only construction time and costs but also contribute to carbon footprint savings. This publication describes cellular foundation mattresses technology called Stratum that consists of 1m high bespoke geocell structure, as described in BS 8006-1: 2010. This solution has been utilised on infrastructure projects such rail and highways, acting as embankments foundations. This paper presents a case study of a highway embankment built in 1990s and is supplemented by recently obtained information on the performance of a road embankment after 30 years from its installation. This example proves the long tracked record of 1m high, bespoke geocell mattresses economical advantage over the alternative traditional solutions. 1m high geocells offer reduction of excavation volumes of unsuitable soils that typically would be replaced with engineered fill, or remove the need for piling works, delivering solutions without compromising on performance.
