Multitrack SNW17 exceeds the Tensile Strength and CBR Puncture Resistance of the competitor product making it stronger and more robust.
Both products are manufactured using a non-woven process so have good elongation characteristics.
The non-woven production process gives both products excellent hydraulic properties.
The greater mass and thickness of Multitrack SNW17 means that the geotextile is capable of absorbing hydrocarbons from leaks and spills and provides an environment for a microbial biomass to develop to allow oil digestion to occur.
Retention testing shows that the Multitrack SNW17 swells and absorbs more oil than the competitor product.
When under load, Multitrack SNW17 retains more than double the amount of oil of the competitor product, thereby allowing the microbial biomass more potential to digest a greater quantity of hydrocarbons.

** A load of 120kPa approximately replicates the load imposed by vehicular traffic on an installed pavement
