Proven Success Building Durable Pavements on Peat
Neoloy® Tough-Cells enhance load-bearing capacity for roads, rails, ports, and platforms on saturated peat soils.
Peat soil, formed from partially decomposed plant matter in waterlogged conditions, poses significant challenges for construction due to its high water content, low bearing capacity, and susceptibility to settlement. Traditional construction methods often result in costly failures and extensive maintenance. Neoloy Tough-Cells provide a robust solution by stabilizing peat soil, creating a long-lasting foundation for road construction.
How Neoloy Tough-Cells Stabilize Soft Peat Soils
Neoloy Tough-Cells are revolutionary geocells designed to reinforce and stabilize weak soils, including peat bogs and swampy areas. By confining and interlocking soil particles within their cellular structure, Neoloy significantly improves soil load-bearing capacity, reduces settlement, and enhances overall stability.
Constructed from NPA (novel polymeric alloy), Neoloy outperforms traditional geocells and other geosynthetics by offering superior modulus and tensile strength. Supported by established design methodologies, published research, and international standards, Neoloy Tough-Cell technology effectively addresses the challenges posed by soft, unstable peat soils:
- Confine and Reinforce Soil: The rigid cellular structure of Tough-Cells provides high tensile strength (>16 kN/m) to peat soil. When filled with granular material (like sand), this structure confines the soil, preventing lateral movement and displacement. For extreme conditions, multiple layers can be used.
- Distribute Loads: The stiff Tough-Cell mattress (elastic modulus >500 MPa) evenly distributes loads across the soil surface. This reduces concentrated stress points, preventing differential settlement and failure common in soft peat soils.
- Improve Drainage: Tough-Cells’ cellular structure and engineered perforations facilitate efficient water drainage, maintaining optimal moisture levels under various conditions. This reduces water content in the peat soil, increasing its strength and stability.
- Create a Stable Foundation: By combining these attributes with high resistance to permanent deformation (<2%), Neoloy Tough-Cells create a stable platform on soft peat soil, ideal for supporting heavy-duty roads and other infrastructure.
Essentially, Neoloy Tough-Cells transform weak, unstable peat soil into a strong, reliable foundation for road construction projects.
Benefits of Using Neoloy Tough-Cells for Peat Soils
- Increased load-bearing capacity: Neoloy’s unique reinforcement significantly enhances peat soil’s ability to support heavy-duty pavements.
- Improved soil stability: By confining and reinforcing peat, Tough-Cells prevent settlement and erosion, ensuring a stable foundation.
- Efficient drainage: The uniquely perforated Neoloy cellular mattress effectively drains water, maintaining soil strength.
- Cost-effective: Neoloy Tough-Cells often require less excavation and fill material compared to traditional methods, resulting in substantial cost savings.
- Accelerated construction: The rapid installation of Tough-Cells can shorten project timelines.
- Environmental benefits: Tough-Cells reduce the need for importing large quantities of fill material, minimizing the project’s carbon footprint.
- Long-term performance: High resistance to permanent deformation ensures a durable and long-lasting solution for peat soil stabilization.
Neoloy Tough-Cell is a proven, worldwide solution for overcoming peat soil challenges. By stabilizing the soil and improving its load-bearing capacity, Tough-Cells enable the successful construction of roads, infrastructure, and other projects on peatland sites.
