Client Heidelberg Cement Ltd.
Location Satpara, Damoh, Madhya Pradesh, India
Application Construction of check dam using StrataWeb® geocells as building blocks
Scope of work Design, supply, and construction

Project Overview

As part of its Corporate Social Responsibility, Heidelberg Cement desired to construct a check dam to store rainwater for the local population for irrigation and other needs. An earlier attempt with an earthen bund was not successful when the structure was washed off during heavy rains. With approaching monsoons of 2018, the Client desired a solution where the designed structure could be constructed rapidly. In response to an enquiry, Strata Geosystems developed an innovative solution of a water retaining with StrataWeb® geocells.


Considering the challenges, construction of the check dam with StrataWeb® as the building block was the optimum solution. The prime factors that led to this innovative system of construction were:

  1. The remote site location and difficult terrain, rendering the site almost inaccessible for normal earthwork equipment.
  2. Undulating ground profile at the proposed location.
  3. Time constraints; the project had to be completed within the stipulated time prior to the onset of monsoon, to commence water harvesting with the very onset of the season.

Conventional approach

The earth structure option was ruled out owing to the previous failure. One option was to construct the structure of plain or reinforced concrete. However, this worked out to be quite expensive and time intensive proposal. The concrete structure would also be a rigid structure and would require appropriate foundation treatment.

Strata’s innovative approach

Considering the site limitations and time constraints, Geotechnical specialists of Strata suggested a technique using their cellular confinement system – the StrataWeb® geocell Style SW 660 200, infilled with locally available material for constructing the wall of the check dam.

The depth of the geocells used is 200 mm and the seam weld spacing is 660 mm. To render the system water-tight to a reasonable extent, the cells congruent to the upstream side was filled with plain cement concrete. The inner cells were filled with compacted local non- plastic soil. To prevent erosion from water flowing through the spillway pipes, the downstream face of the completed structure was gunited with cement mortar, with waterproofing admixture. To further ensure that there is no build-up of internal pore water pressure due to the guniting, weep-hole pipes were placed at appropriate intervals. Overflow was designed to take place through 250 mm nominal diameter pipes placed at intervals of 510 mm centre to centre. With these innovations, the construction was rapid and timely completion was ensured.


  • There was saving up to 40% of the cost, compared to the conventional retaining wall solution.
  • The work could be completed within stipulated time since installation of StrataWeb® is super-quick
  • Considering the material characteristics of the HDPE that goes into the fabrication of StrataWeb® geocells, the solution is sustainable and environmentally friendly.
  • No other solution could have been executed as fast, economical and effective.
