A container freight station (CFS) is where cargo shipments are merged or de-combined and staged between transport legs. A CFS is commonly situated close to a sea, port, or air terminal where payload holders are moved to and from. These areas typically have weak soils. The client required ground improvement of subgrade for the CFS region having a low bearing limit.
The yard needed to be designed to accommodate 4 containers per stack with a Dry Lean Concrete (DLC) below interlocking Pavers, and this was making the project expensive. A subgrade section would have to be made below the paver blocks. The solution also required the yard to withstand the heavy loads of completely loaded reach stackers and be robust enough for the ongoing movement of trailers carrying fully loaded containers.
Strata’s group of geosynthetic experts proposed a solution with StrataWeb® geocells, biaxial geogrid and a non-woven geotextile. Introducing StrataWeb® in the granular base or sub-base improves the pavement’s life span and economizes the overall crust thickness. Biaxial geogrid increases the stiffness of aggregate base layers and confines the aggregate particles under repetitive loading.
Strata’s innovative solution helped with faster execution of work due to ease of installation of the products saving significant construction time.
