Reshaping the future of landfills
Vertical expansion · Zero leakage · Ecological restoration
Weiwo provides globally leading reinforcement and drainage technologies to solve land scarcity problems and ensure safe management of leachate.
Vertical Expansion: MSE Guardrail System
Increasing the elevation within existing land areas is the best solution to address reservoir capacity pressure. Weiwo utilizes high-strength polyester geogrid reinforcement technology to construct steep reinforced soil slopes (MSEBerms).
- Compared to traditional slopes, this can save over 40% in land acquisition costs.
- It also enhances the bearing capacity of the foundation, effectively resisting uneven settlement of the fill.
High-efficiency drainage: leachate and gas management
The core risk of landfills lies in liquid accumulation. We use a three-dimensional composite drainage network to replace the expensive gravel drainage layer, which is not only quick to install but also provides a smoother drainage path.
- It replaces the traditional 30cm gravel layer, directly increasing the effective burial depth capacity.
- High drainage efficiency prevents methane gas from accumulating inside the landfill.
Ecological restoration: Site closure and capping system
After landfill closure, Weiwo provides a multi-tiered capping system to prevent rainwater infiltration and enable surface revegetation.
- Geocell soil stabilization technology prevents the cap layer from sliding down slopes.
- This transforms brownfield sites into eco-parks or photovoltaic power plant sites.
