What Are Geosynthetics? A Complete Beginner’s Guide
                     What Are Geosynthetics?
Engineered synthetic materials revolutionizing modern 
construction, infrastructure, and environmental protection.
Definition & Purpose
What They Are Core Applications
Geosynthetics are engineered Used to separate, reinforce, 
synthetic materials made from filter, drain, and contain 
polymers like polypropylene, surfaces including:
polyester, and HDPE. They 
• Slopes and embankments
interact with soil or rock to 
improve mechanical and • Foundations and retaining 
hydraulic properties. walls
• Landfills and reservoirs
Etymology: "Geo" (earth) + 
•
"synthetics" (human-made) = Roads and railways
materials designed to 
safeguard earth surfaces.
8 Key Functions of Geosynthetics
Separation Filtration
Prevents mixing of distinct soil layers, maintaining Allows water flow while retaining soil particles for 
load-bearing capacity in roads and railways. efficient drainage systems.
Reinforcement Barrier & Containment
Improves soil strength and deformation properties Prevents liquid/gas passage in landfills, reservoirs, 
for stable structures. and salt barriers.
Drainage
Directs water or gases to designated outlets, protecting structures 
from hydrostatic pressure.
Protection
Shields vulnerable materials from puncture or damage during 
installation and service.
Erosion Control
Protects soil from rainfall, runoff, and wave action on shorelines and 
slopes.
Stabilisation
Spreads loads over wider areas, increasing bearing capacity on 
weak subsoils.
