Reservoir Slope and Liner Protection with StrataWeb in India

A Megawatt thermal power plant is under construction near Gandhidham, Gujarat India by OPG Power Ventures. A raw water reservoir was created with a storage capacity of 50,000 cubic meters, to stockpile and ensure constant supply of cooling water. It was lined with 22mil thick geomembrane to render the bottom and side slopes impervious. The geomembrane-lined slopes and bottom required protection from external damage and uplift pressures. Ideally, a reinforced concrete lining is installed above the geomembrane. However, due to steep slopes combined with the weight of concrete tiles or poured concrete as the case may be, the liner would slide down causing system instability. Using StrataWeb® geocells filled with lean concrete proved to be a technically superior and cost effective solution.

StrataWall Brings Beauty And Stability To Urban Park

The Challenge The Ray and Joan Kroc Corps Community Center is a 20-acre education, recreation and cultural arts and worship facility that provides an oasis of green space in urban Grand Rapids, Michigan. With both topographical and economic challenges to consider, the center’s managers were seeking a cost-efficient and attractive solution to stabilize grade changes near the outdoor amphitheater. The project area would serve as a backdrop for concerts, ceremonies, outdoor movies and community events, so appearance was a priority. The Solution A 15’ tall x 300’ long three-tier retaining wall faced with galvanized welded wire forms was designed. Each tier provided attractive horizontal planting areas for shrubs and flowers and the vertical wall face was planted with ivy. The wire forms allowed for some minor movement without distressing the structure, or causing cracks. It also tolerated a certain amount of settlement, making it a desirable solution especially in relatively poor subsoil and backfill conditions. Strata Microgrid, SG200 and permanent turf reinforcement mat were used to reinforce and retain the soil behind the wall. A drip irrigation system was installed to hasten establishment of the vegetation and assure a green solution throughout the year. Strata provided preliminary design cross sections for cost estimating which enabled accurate bids by the landscape contractor, Twin Lakes Nursery. Results The StrataWall is a beautiful asset to the center adding green to the area while retaining the soil and keeping costs within budget. The welded wire form wall fit nicely into the overall landscape plan, providing a strong, yet flexible MSE system that was easy to install and adjusted to fit the varying conditions... read more
