LOCATION
Satpara, Damoh, Madhya Pradesh, India
Client
Heidelberg Cement Ltd.
Product used
StrataWeb® 660-200
Application
StrataWeb® used for construction of check dam
About the project
Heidelberg Cement Ltd. desired to construct a check dam to store rainwater for irrigation and other needs for the local population. Challenges of this project included remote site location and difficult terrain, rendering the site almost inaccessible for normal earthwork equipment, along with undulating ground profile and time constraints.
Geotechnical specialists of Strata suggested a technique using their cellular confinement system – the StrataWeb® geocells style SW 660-200, infilled with locally available material for constructing the wall of the check dam. To render the system water-tight to a reasonable extent, the cells congruent to the upstream side were 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 covered with gunite - a cement mortar waterproofing admixture.
Weep-hole pipes were placed at appropriate intervals. The 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.
Approx. 40% of the cost was saved, thus delivering a quick, economical and effective solution.

MORE SUCCESS STORIES
Strata Geosystems uses eco-friendly solution with geogrid at KuberTila, Ram Mandir
The Kuber Tila project, located in Ram Mandir, Ayodhya is a small hillock within the temple grounds. It underpins the Ram Van Gaman path – symbolising the journey of Lord Ram from Ayodhya to Lanka. The engineering team identified the need for slope retention.
Construction of StrataWeb® Geocell Wall 32m high RS wall in the state of Manipur
This project encompasses a total length of 111 kilometers, posing the challenge of limited Right of Way (ROW) availability on either side of the proposed road’s centerline. To address this constraint, there was a need to stabilise steep slopes, manage deep cuttings, or contain filled soil within the ROW.
A total of 34 locations were identified as critical areas with deep filling requirements
Building of RS Wall Along 42KM Highway
Strata undertook a significant project involving the design and construction of Reinforced Soil (RS) wall approaches along the NH-363 highway, spanning a 42-kilometer stretch from Mancherial to Repallewada in Telangana.
The client’s primary requirement was to find a cost-effective and efficient alternative to the conventional approach of using Reinforced..
