STRATA GLOBAL

OVERVIEW

Sturdiness inspired by nature

One of nature’s strongest structural shapes is the three dimensional honeycomb. StrataWeb® (geocell) applies this shape to soil reinforcement to solve some of today’s most difficult civil engineering problems associated with load support over soft soils, erosion on steep slopes and the lining of lagoons, drainage channels and landfills. The StrataWeb® three-dimensional cellular confinement system is used to improve load-bearing capacities, reinforce weak soil foundations, and control erosion on slope surfaces. It can also help alleviate challenges associated with load support over soft soils and erosion on steep slopes, as well as the lining of lagoons, drainage channels, and landfills. StrataWeb® utilizes strips of extruded polymer welded together at intervals that when expanded, form a three dimensional honeycomb mattress.

Filled with granular material, the resulting cellular confinement system efficiently transfers compressive and tensile stresses from heavy loads to provide higher load support capacity than any geosynthetic or geogrid product available.

MANUFACTURING

How it’s made?

The system utilizes strips of extruded polymer welded together at intervals that when expanded, form a 3-dimensional, honeycomb mattress. Filled with granular material, the resulting cellular confinement system efficiently transfers compressive and tensile stresses from heavy loads, to provide higher load support capacity than any geosynthetic or geogrid product available.

APPLICATIONS

What can StrataWeb® simplify?​

We guide engineers, contractors, and owners to use StrataWeb® to achieve cost effective, sustainable, and reliable solutions for various site development challenges.

Erosion Control

The confinement action of StrataWeb® reduces erosion on slopes caused by rain, 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. It provides a cost-effective and long-lasting 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 soil, concrete, and gravel. StrataWeb® proves to be more economical compared to stone pitching and paver tiles and is substantially longer lasting as compared to jute/coir mats. StrataWeb® can be purchased along with the anchoring systems – StrataLock, StrataCord, and StrataFast. These are the connectors that bind the geocell panels together.

Load Support

Due to the confinement effect and honeycomb structure, StrataWeb® spreads the loads forming on top over a larger area, effectively increasing the infilled material's modulus. StrataWeb® is very useful 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.

Drainage/canal lining

Almost all sites face drainage as a tedious challenge. We can fix this for you. Our drain lining system offers flexible lining that will conform better to the shape distortions and can withstand the stresses of flowing water. This type of system using StrataWeb® ensures uniformity across the concrete layer, and the quality control offered is unmatched. The ease of installation provides a 30% saving in construction time.

Slope liner protection

In cases where a geomembrane liner or any such surface is used on the slope, which cannot be damaged or punctured, the StrataWeb® liner protection system is the perfect solution. StrataWeb® can be laid on the liner without any requirement of puncturing the liner and is anchored at the slope's crest. 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.

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 need substantial time. A StrataWeb® retaining wall is an optimized solution for such projects. The wall can be designed either as a geogrid reinforced soil wall or as a gravity wall. Since the StrataWeb® wall panels are manufactured and shipped to the site, minimal site activities are required. StrataWeb® retaining walls combined with StrataGrid™ provide one of the fastest construction period with minimal disruption at the site requiring only standard earthwork. Additionally, StrataWeb® walls provide the option for a green aesthetic facing by allowing vegetation to grow at the face.

QUALITY TESTING

How long does it last?

Geocells are robust due to its three-dimensional structure. An edge ahead of its two-dimensional geosynthetic reinforcements. However, design using geocells is complex considering raw material used, depth, weld spacing, infill and type of application. The long-term performance of a geocell is still a research domain across the world. However, it is vastly dependent on numerous factors such as raw material, process of manufacturing, the designs, and the end application. 

Since, geocells are used for critical designs, it is essential to have a clear understanding of its durability. StrataWeb® undergoes exhaustive testing at internationally reputed laboratories to define all of the above factors.

Stages of testing

CASE STUDIES

Perfect instances of StrataWeb® doing its job

Drain lining for Railways

Security is a top priority in the shipping industry. So, when plans for DHL’s new 2,90,000 square foot distribution facility in Allentown, Pennsylvania, called for 3,450 linear feet of retaining wall along the perimeter of the 72-acre site.
