Product Information
Full details
The Lowtrak 100 is a mechanically bonded nonwoven geotextile designed for construction professionals needing reliable separation and filtration. Its key benefit is preventing aggregate loss and ensuring soil stability in various ground conditions, though it requires proper installation to maintain its integrity. This guide covers its applications, benefits, and maintenance for effective use.

FAQs
What is the primary function of Lowtrak 100?
Lowtrak 100 is primarily used for separation and filtration in construction applications. It prevents different materials (like soil and aggregate) from mixing and allows water to pass through while retaining soil particles.
Can Lowtrak 100 be used for soil stabilization?
Yes, it contributes to soil stabilization by preventing the loss of granular materials into softer subsoils, thus improving the load-bearing capacity of the base layers.
What is the recommended overlap for Lowtrak 100 sections?
A typical overlap of 12 inches (300mm) is recommended, but this should be confirmed against specific project engineering designs.
How should Lowtrak 100 be stored before use?
Store rolls in a cool, dry environment, protected from direct sunlight and weather. Keep them upright and avoid stacking heavy items on top.
Is Lowtrak 100 suitable for reinforcing soil?
Lowtrak 100 is designed for separation and filtration, not for high-tensile strength reinforcement. For reinforcement applications, specific geosynthetic reinforcement products should be considered.
What happens if Lowtrak 100 is exposed to sunlight for a long time?
Prolonged exposure to UV radiation can degrade the geotextile's properties over time. It should be covered with soil or aggregate as soon as practical after installation.
Troubleshooting
Geotextile tears during placement of aggregate
Ensure aggregate is placed gently, not dumped from height. Use lower ground pressure equipment or a layer of aggregate as a protective buffer. Check for sharp objects on the subgrade.
Poor drainage observed after installation
Verify that sufficient overlap was used between geotextile sections. Ensure the geotextile is not blinded by fine silt, which could indicate inadequate filtration or clogging of the aggregate layer itself.
Aggregate loss into subsoil persists
Confirm that the Lowtrak 100 was laid directly on the subsoil and that aggregate was placed on top. Check for insufficient overlap or damage to the geotextile layer.
Pros and Cons
Pros
- Effectively separates dissimilar soil and aggregate layers.
- Provides excellent filtration to maintain soil structure and water flow.
- Durable mechanically bonded structure for reliable performance.
- Reduces aggregate loss, leading to cost savings in construction.
- Versatile for use in road construction, trench lining, and general civil engineering.
Cons
- Requires careful installation to avoid damage or improper function.
- Not designed for high-tensile strength reinforcement applications.
- Performance can be affected by extreme chemical contamination.
- Susceptible to UV degradation if left exposed for extended periods without cover.
Setup, Compatibility & Care
Setup:
- Preparation: Ensure the subgrade is clean and free from debris. Excavate trenches to the required dimensions.
- Placement: Unroll the Lowtrak 100 geotextile smoothly over the prepared surface. Avoid wrinkles and folds.
- Overlap: Ensure sufficient overlap between adjacent sections, typically 12 inches (300mm) or as specified by project design. Stagger seams where possible.
- Placement of Materials: Carefully place aggregate or fill materials over the geotextile. Avoid dropping materials from a height or using heavy equipment directly on the un-covered geotextile to prevent damage.
Compatibility:
The Lowtrak 100 is compatible with common construction aggregates, soils, and drainage pipes. It performs well in typical pH ranges found in soils. Avoid prolonged contact with highly aggressive chemicals.
Care:
- Storage: Store rolls in a cool, dry place, protected from direct sunlight and extreme temperatures. Keep rolls upright to prevent deformation.
- Handling: Handle rolls carefully to avoid puncturing or tearing the material. Use appropriate lifting equipment if necessary.
- Protection: Once installed, cover the geotextile with fill material as soon as possible to protect it from UV radiation and physical damage. If exposed to sunlight for extended periods, its properties may degrade.
