Global Synthetics GS_015 Pro Grid PP Geo Composite Geogrid Instruction Manual
Biaxial soil reinforcement, stabilization & separation recomposite
Product Information
ProGrid® PP Reinforcement Geocomposite is formed by punching holes and stretching a stiff polypropylene sheet to form a geogrid with uniform openings which then has a polyester (PET) nonwoven geotextile heat bonded to one side.
ProGrid® PP Reinforcement Geocomposite provide stiff, high modulus reinforcement with the added benefit of separation and filtration. These features combine to allow the construction of roads and other amenities over weak, low bearing subgrades.
Applications
- Base, sub-base stabilisation and reinforcement
- Subgrade / soil stabilisation and reinforcement
- Raft reinforcement construction
- Road, railway and airport pavements
- Suitable for placement directly on subgrade due to separation benefits of the attached geotextile
ProGrid® Polypropylene (PP) Geocomposite
Benefits and Features
- Reinforcement/stabilisation, separation, filtration and drainage combined. Making installation easier and faster in a single operation to provide significant cost and time savings
- Increases lateral confinement of unbound & modified gravel material layers
- Improves soil/subgrade bearing capacity
- Helps control expansive soil/subgrade movements and associated longitudinal cracks in sealed road pavements
- Robust against installation damage, and chemical and biological attack
