Ballast reinforcements and railway sub-ballast
Track reinforcements: Reinforcement of ballast and sub-ballast of railways
Solutions tested and approved on the world's major rail networks.
The StrataBase geogrid or the geocélula Strataweb, arranged in the ballast and sub-ballast layers or between one of these and the subgrade, provide reinforcement to the railroad structure maximizing its performance_cc781905 -5cde-3194-bb3b-136bad5cf58d_e minimizing intervention and repair costs.
With the ability to keep granular material confined, these reinforcements ensure a maintenance of the railroad structure and its properties.

Operation
More than one utility: The improvement provided by the StrataBase and StrataWeb boosters is attributed to three key mechanisms:
-
Lateral constraint of displacements: primary mechanism of reinforcement that can be translated as a lateral constraint of the base/sub-base aggregate (ballast/sub-ballast) when it is subjected to surface loads.
-
Improved load capacity: as StrataBase and StrataWeb are materials with high tensile strength, they promote greater soil mobilization, generating greater support capacity in addition to reducing the stress on the subgrade.
-
Membrane Effect: When requested, StrataBase and StrataWeb assume a tensioned membrane shape that provides a reaction to the stress supporting the imposed load.

Features
- Reinforcement installed in the granular layer or in the subgrade contact to optimize the application.
- Rigid geogrids perform better than woven and geotextiles.
- The StrataWeb geocell has the best performance among reinforcements.
- Geogrid joint strength and stiffness are the most important parameters.

Products
StrataBase Geogrids
StrataBase® is a rigid biaxial geogrid that offers structural reinforcement for roads, paved and unpaved, through its high rigidity, dimensional stability and high strength of its connections.
StrataWeb Geocells
StrataWeb® geocells are produced with strips of extruded polymer welded into joints that, when expanded, form a three-dimensional honeycomb mattress.
StrataGrid Geogrids
StrataGrid® is a geosynthetic
high performance project designed to enable soil reinforcement projects in containment systems, soft soil improvement_cc781905-5cde-3194-bb3b-136bad5cf58d-de905-57 136bad5cf58d_base reinforcement of highways, with safety and ease of application.
