Neoloy based geocells VS HDPE geocells

Not all geocells are the same. While HPDE Geocells have relatively low tensile strength, high creep and low dimensional stability, Neoloy Geocells have high modulus and tensile strength, making them suitable for long-term applications.

Benefits of PRS Neoloy Geocells over HDPE Geocells

• Higher tensile strength – up to 24 kN/m
• Higher flexural storage modulus – 3-10x higher plastic deformation (creep) resistance
• 2 to 5x higher dimensionally stable in a much wider temperature range
• Significantly more resistant to stress-cracking
• Very high resistance to elevated temperatures up to 60°C
• 10x more resistant to oxidation and UV degradation over time

Recent research has broadened our understanding of geocells and the reinforcement mechanisms. The results prove that not all geocells are equal – a key to performance is the elastic modulus of the geocell.

Geocells manufactured from HDPE have relatively low tensile strength, high creep and low dimensional stability.

HDPE geocells are unsuitable for long term applications, particularly when subject to heavy duty cyclical loading and elevated temperatures.

Neoloy Geocells maintain their engineering properties over time, under heavy loading and under high temperatures. This has been confirmed by numerous plate-load tests, numerical modeling and full scale trafficking tests (see Neoloy Published Research). Neoloy has demonstrated greater improvement in stiffness, bearing capacity, stress distribution and reduced deformation, when compared with conventional HDPE geocells. The high modulus and tensile strength of Neoloy make it the most suitable geocell for long-term use in motorways, railways and earth retention.
