StrataWeb® as Slope Protection at the reservoir


Application Slope Protection for reservoir lining using StrataWeb® geocells.
Location L&T Knowledge City, Vadodara, Gujarat, India
System Offered Design, supply, and supervision StrataWeb® Geocells StrataWeb®SW660 x 125
Project Size 1.2 Acres (5000 sqm)

Project Overview

The L&T Knowledge City at Vadodara in Gujarat is the hub of several key businesses for the corporation. The Power business, Mid & Downstream Hydrocarbon, Technology Services, and the engineering JV L&T Sargent & Lundy operate out of this facility. The existing reservoir in the premises was becoming difficult to clean and maintain due to soil erosion and subsequent turbidity.

The Challenge

The steep slope of the reservoir was close to the road that had heavy traffic. Therefore, while executing the project, it was crucial to eliminate any erosion from the top of the road’s crest. In addition, the curvature of the slope provided some additional challenges but was overcome by Strata’s solutions.

Conventional Method

Using the conventional method, manually laid dry 300 mm thick stone would’ve been needed with skilled labor. This made the project more time consuming and expensive. It would have also required RCC bend to take the weight of the stone along the sloping face which is an added cost for the project.

Strata’s Innovative Solution

StrataWeb® SW660 x 125 was installed and infilled with concrete over a geomembrane. The StrataWeb® style was selected in such a way that there was no need for connection along the length of the slope. i.e. the slope of the reservoir was 12 meters and the StrataWeb® panel was 12.63 meters.

Strata's Value Addition

  • Extremely easy installation with unskilled labour (watch the installation video here)
  • Maintained the scenic view of the reservoir without any obstruction
  • 20% transportation cost savings as StrataWeb®’s truck loading is extremely efficient
