Today, geotextiles are often been utilised in a variety of applications to resolve many different issues, whether it be one of drainage, separation, filtration or reinforcement. Geotextile fabrics can provide the strength and stability necessary to enhance and control flows in a location. Perhaps one of the lesser known applications for this versatile fabric, is that of its role as a cushioning layer.
Things to consider when selecting a cushioning geotextile:
a. Understanding the long term properties and stress analysis of your selected barrier system
b. The guidelines and testing used to determine the characteristics of your geotextile: mass; thickness and puncture, based on Australian and International Standards.
c. The elongation capacity of the geotextile, as this will dictate the resistance to damage.
d. The mass of the rolls of the geotextile, generally the larger mass rolls of geotextile provide the best cushioning protection.
