GEOLOK™ is a high-performance, multi-material geocell system with a patented mortise-tenon interlock that offers far superior strength, adaptability, and cost-efficiency over traditional welded HDPE geocells, making it ideal for heavy-load and extreme-environment ground stabilisation.
GEOLOK™ is a next-generation geocell with a mortise-tenon mechanical interlock system, designed to provide superior structural stability compared to traditional welded HDPE geocells. It is available in PET, PP, and composite PE variants, allowing it to be tailored to environmental and loading requirements. Its 3D confinement structure increases soil shear strength, reduces deformation, and distributes loads more effectively.
GEOLOK™ is purpose-built for heavy-load, high-performance ground stabilisation in demanding environments, offering exceptional structural strength and long-term cost efficiency.
It is widely used for subbase and soft ground stabilisation, improving the load-bearing capacity of roads, highways, railways, and heavy-load platforms.
GEOLOK™ also delivers stable, confined backfill for retaining walls, minimising settlement and structural movement over time.
By controlling lateral soil displacement, it significantly reduces rutting and deformation in saturated or poorly compacted soils, ensuring a longer service life for the surface layers above.
The system’s versatility extends to erosion and sand control applications, such as desert sand fixation, riverbank stabilisation, and coastal protection.
Engineered to perform reliably in extreme climates, it maintains its integrity in both high-temperature and freezing conditions, as well as in chemically aggressive environments where traditional geocells are prone to degradation.
Strength & Durability:
GEOLOK™ has much higher yield strength (180 kN/m vs 25 kN/m) and peel strength (80 kN/m vs 14.2 kN/m).
PET version offers excellent temperature resistance (-40 °C to 120 °C) and service life over 30 years in extreme environments, whereas HDPE softens at high temperatures, becomes brittle at low temperatures, and degrades faster in chemical/UV exposure.
Material Options:
GEOLOK™ uses PET, PP, or composite PE, chosen for specific conditions.
Welded geocells only use HDPE, limiting adaptability.
Construction Efficiency:
GEOLOK™’s large mesh design speeds up installation by up to 40%, allows one-time filling, and adapts to various subgrades (even construction waste).
HDPE welded geocells require smaller mesh, higher tension, more compaction steps, and better-quality subgrade.
Cost Efficiency:
GEOLOK™ reduces fill thickness, material needs, and long-term maintenance, lowering life-cycle costs by ~35–40%.
HDPE welded geocells often require additional cushion layers and high-quality subgrade materials, increasing costs.
Applications:
GEOLOK™ is suitable for high-load, extreme-environment applications such as highways, railways, runways, and desert sand fixation.
HDPE welded geocells are generally limited to slope protection and light-load, stable conditions.
