StrataWeb - Geocell for Three-Dimensional Honeycomb Shaped Cellular Confinement System

SHARE

StrataWeb (Geocell) is a lightweight, but strong, three-dimensional honeycomb shaped cellular confinement system. It can be used as a foundation reinforcement mat for improvement of load bearing capacities of weak soils and as an erosion control barrier for slope surfaces. As a load support system, StrataWeb effectively improves the load carrying capacities of weak soils. The strong, yet flexible cellular structure of StrataWeb confines the in-filled material and creates a stable base for load distribution. StrataWeb may be used within road sections/ container yard pavements or below foundations, essentially to distribute the imposed load over a larger area. StrataWeb geocell slope protection system is a low-cost, high performance solution that addresses slope erosion challenges while providing several facing options such as vegetation for aesthetic cover, concrete for permanent cover etc., thereby enabling a sustainable footprint.

Manufacturing
StrataWeb manufacturing involves extruding the base polymer using laser controlled processes to ensure accuracy throughout the batch. After, extrusion the sheets are perforated through a high power punching machine and then finally the joints are welded using advanced ultrasonic welding machines which provides the highest weld strength possible.
Erosion Control
The confinement action of StrataWeb® reduces erosion on slopes arising due to rains, wind and other factors. StrataWeb® protection system can be engineered to suit slope conditions, from very steep 60 degree slopes to very gradual 27 degrees slopes, and provide a cost effective solution. After the slope is dressed and compacted StrataWeb®can be expanded and installed rapidly using Strata connectors and anchor systems.

Multiple infill options are available including vegetation, concrete, stone or any other option suitable to the site. StrataWeb® proves to be more economical as compared to stone pitching and paver tiles and is substantially longer lasting as compared to jute/coir mats.

Slope liner Protection
In cases, where a geomembrane liner or any such surface is used on the slope which cannot be damaged or punctured, StrataWeb® liner protection system is the perfect solution. StrataWeb® can be laid on the liner without any requirement for puncturing the liner and is anchored at the crest of the slope. The crest anchorage is engineered to withstand all the sliding forces arising in StrataWeb®. StrataWeb® liner protection system can also be designed for very steep slopes.
Load Support
Due to the confinement effect and honeycomb structure, StrataWeb® spreads the loads forming on top over a larger area effectively increasing the modulus of the infilled material. StrataWeb® is very effective for pavements, ground improvement below embankments, access roads etc. over poor subgrades such as expansive soils, black cotton areas, etc. It can be engineered for heavy loading and several site conditions.

Installation of StrataWeb® is extremely simple, requiring no machinery and can be done rapidly. StrataWeb® load support solution is ideal for low CBR grounds with heavy loading requirements and will help save on natural resources by reducing the aggregate layers.

Retaining Wall
In several projects, where change of grade challenges are encountered, retaining walls are required. Typical concrete retaining walls are expensive to construct and require substantial time. A StrataWeb® retaining wall is an optimized solution for such projects. The wall can be designed either as geogrids reinforced soil wall or as a gravity wall. Since, the StrataWeb® wall panels are manufactured and shipped to site, minimal site activities are required.

StrataWeb® retaining walls in combination with StrataGrids™ provide one of the fastest construction period with minimal disruption at site requiring only standard earthwork. Additionally StrataWeb® walls provide the option for a green aesthetic facing by allowing vegetation to grow at the face.
