Flooring base and sub-base reinforcements
Road reinforcements: Floor reinforcement and sub-floor
Description
The StrataBase Geogrid or Strataweb Geocells, arranged in the base or sub-base layers or between one of these and the subgrade, provide reinforcement to the road structure, maximizing pavement performance and minimizing costs.
The use of these products allows the application of two design concepts (or the association between them):
- Reduction of pavement thickness, with immediate reduction of costs associated with excavation, use of granular materials for base and sub-base and activities related to these as transport, spreading and compaction;
- Increase in the useful life and serviceability level of the pavement due to the greater structural resistance of the pavement with the presence of reinforcement.

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.

Products
StrataBase Geogrids
StrataBase® is a rigid biaxial geogrid that offers structural reinforcement for paved and unpaved roads through its high rigidity, dimensional stability and high strength of its connections.
Geocélulas StrataWeb
StrataWeb® geocells are produced with strips of extruded polymer welded into joints that, when expanded, form a three-dimensional honeycomb mattress.
