  • Geotex® Geotextiles: A Life Cycle Costing Approach to Roads

    Subgrade contamination is the leading cause of failure in both pavements and unpaved roads. Aggregate layers used to support the traffic or pavement typically rests on a subgrade of sand, silt or clay. Without permanent separation, two factors will undoubtedly lead to the contamination of the aggregate layers—fine-grained soils will enter into the voids of the aggregate, preventing it from ...

  • Treatment of domestic greywater by geotextile filter and intermittent sand filtration bioreactor

    Intermittent sand filtration (ISF) is an efficient system for treatment of greywater; however, the high quality of effluent and the simple set-up contrast with the high failure rate due to clogging of surface layers. The efficacy of several polypropylene non-woven geotextiles (apparent opening size from 0.10 to 0.18 mm) used as primary treatment filters to remove suspended particles from ...

  • Creep not a factor for Geocell load support

    An accurate understanding of creep resistance is essential to proper material selection when using polymers, and in the case of geocells, this science is being misapplied.  The definition of creep deformation is the tendency of a solid material to move slowly or deform permanently under the influence of mechanical stress.  Creep is something that creates fear and uncertainty with all ...
