Reinforced Retaining Wall Nairobi to Thika Expressway, Kenya
Project Introduction: The Nairobi-Thika Expressway in Kenya is nearly 50 kilometers long and is the main road connecting the capital Nairobi and the northern industrial town of Thika. This expansion will expand the original two-way four-lane to two-way eight-lane. Among them, there are the longest two-way four-lane highway bridges, underground passages, pedestrian bridges, etc. in […]
Reinforced Earth Retaining Wall: Mombasa-Mariakani Expressway Project, Kenya
Project Introduction: The Nairobi-Mombasa Highway (A109) in Kenya connects the capital Nairobi with the largest port in East Africa, Mombasa Port. It is the most important sea-to-land transportation artery in Kenya. About 80% of the import and export goods from Uganda, Rwanda, Burundi, South Sudan and eastern Congo (DRC) must pass through it. The proposed […]
Case Study: Geosynthetics Used in Solid Waste Field Anti-seepage Project
The industrial solid waste disposal project in Yunxi District utilized geotechnical materials such as geomembranes, filament geotextiles, GCL bentonite waterproof blankets, and composite drainage nets, all provided and implemented by QIVOC. Despite challenges such as geological conditions, overlapping operations, and the pandemic, the project was completed. Project Overview The industrial solid waste disposal project in […]

Application Cases of Geotextiles in Reservoir Dams
A certain dam was completed in August 1955, with a designed storage capacity of 13.5 million m3, a dam height of 21.15 m, and a dam crest elevation of 1870 m. Because the dam foundation has a soft soil layer, the main dam is an arched homogeneous earth dam that curves upstream, 660 m long, […]
Uniaxial Geogrid Used in Slope Protection and Greening Project Case
The network structure has the functions of gathering soil, increasing the overall stability of the slope, and repairing the landslide slope. In mountainous areas with active earth crust, one-way geogrids are often used for mountain reinforcement and protection. After laying one-way geogrids on the slopes, the soil can be gathered, so that the slopes can […]
HDPE Pond Liner Used In Marine Shrimp Pond Breeding Projects
Use high density polyethylene pond liner to build shrimp ponds for breeding fish and shrimps. Project Overview: A customer wanted to buy some polyethylene pond liners to build a pond. He has an animal and food processing factory with a large open space that he wants to use to build a shrimp pond and learned […]
Geotextile Project Case: Protection of Upstream and Downstream Banks of Water Gates Against Erosion
In this project, geotextiles were employed to reinforce the banks both upstream and downstream of water gates, providing protection against erosion and ensuring the safe operation of the water gates. Project Overview: The Xi River embankment commonly features reinforced concrete box bottoms and prefabricated beam-type retaining walls for water gates. This type of watergate offers […]
Geotextile Used In Rural Road Construction Projects
Laying geotextile separation layers during the construction of rural roads can effectively enhance the lifespan and safety of the road, while also providing multifaceted protection to the road structure and the environment. In this project, the length of the road section with geotextile separation layers is 4670 m. The width of the installation is 9.88 […]
Success Story of HDPE Geomembrane in Remediation of Waste Residue Dumping Sites
The project involves the accumulation of solid waste, particularly smelting residues, generated annually by a large-scale mining enterprise. Due to the lack of any environmental protection measures at the deposition site, the waste residue heaps contain significant amounts of heavy metals such as lead, zinc, cadmium, and germanium. This has resulted in substantial pollution of […]
