Primary Functions
1. Separation
Prevents intermixing of different materials (soil/aggregate, soil/concrete) while maintaining structural integrity and improving load-bearing capacity.
2. Filtration (Reverse Filtration)
Allows water flow while effectively retaining soil particles, sand and small aggregates to maintain engineering stability.
3. Drainage
Creates drainage channels within soil structures to remove excess liquids and gases.
4. Reinforcement
Enhances soil tensile strength and deformation resistance, improving structural stability.
5. Protection
Dissipates concentrated stresses from water erosion to prevent soil damage.
6. Puncture Protection
When combined with geomembranes, forms composite waterproofing systems with excellent puncture resistance.
