  • Geotextiles in Dewatering (.pdf)
    Soil erosion isn't just a problem for farmers, Niagara Falls and the Grand Canyon. Most construction projects have to contend with the effects of water on excavations-not only as a consequence of rainfall runoff but also from ground water intrusion. The mud common to most jobsites at one point or
  • Organic Materials in Civil Engineering
    Organic Materials in Civil Engineering. Addressing the various types and characterizations, this book presents an inventory of organic materials and products for civil engineering, from bitumen for roads and geotextiles for retaining walls to membranes for tunnels and reservoir waterproofing
  • Plastic Compounder's PET Project: Recycling
    . To make clean PET flakes, the bales go through cleaning and other processes, including manual separation to remove contaminants, grinding, washing, and drying. Additional extrusion and pelletization may also be involved. Recycled PET finds its way into carpet fibers, geo-textiles, and fiber fill

This is a method that allows dewatering in depths of about 20 ft. The system involves geotextile points that are centered around
