  • Geotextiles in Construction Dewatering

    Woven geotextiles work wonders in dewatering applications as wraps around well screens and sump pit screens. The textile can be sewn into sleeves or tubes to be slid over the well screen or sump pit framework. This technique allows the user to compensate for well screens with slots that are too large or for sump pit piping with large perforations. By adding the geotextile sleeves the user ...

  • Laboratory Properties of a Soft Marine Clay Reinforced with Woven and Nonwoven Geotextiles

    This paper is concerned with the laboratory properties of a geotextile-reinforced compacted soft marine deposit with respect to its compaction, compressive strength, and time-dependent settlement characteristics. Two different geotextiles, namely, Polyfelt TS-500 (nonwoven) and Cardon SG PP 150 (woven) have been investigated. It was observed from the experimental study that a nonwoven geotextile ...

  • Pore Size Distribution of Nonwoven Geotextiles

    The applicability of the mercury intrusion technique to determine the pore size distribution (PSD) of geotextiles was evaluated. The method was found to be simple and rapid, and an ASTM standard for soils and rocks already exists (ASTM Test Method for Determination of the Pore Volume and Pore Volume Distribution of Soil and Rock by Mercury Intrusion Porosimetry [D 4404]). The PSD determined from ...

  • The Basics of Slope Stability Analysis for Geosynthetics

    Slope stability analysis is vital to preventing slope failures in a variety of engineering applications including landfill design, roads, dams and embankments, to name a few. Proper analysis anticipates both natural and manmade slopes and failure of foundations and retaining walls. This blog covers the necessity of slope stability analysis, how to conduct the analysis and the role of ...

  • Using Coir Geotextiles for soil erosion control

    One of the most effective and yet natural soil erosion prevention techniques is the use of Coir Geotextiles fabrics ( Woven Geotextiles). Used extensively to prevent environmental degradation Geotextiles have no synthetic material but is instead made out of an organic fiber, coir, which is extracted from the husk of a coconut. It is strong, durable, water proof and is one of the few natural ...

  • Long-Term Filtration Behaviour of Soil-Geotextile System

    In addition to soil retention and permeability requirements for a geotextile filter, a geotextile should be able to function without having a significant number of its openings clogged. In order to evaluate the long-term filtration behaviour of a soil-geotextile system, a permeameter is developed in which both the long-term flow rates as well as the gradient ratio tests can be conducted ...

  • Effect of Dissolved Oxygen (and Bubbles) on the Measured Permittivity of Geotextiles

    Measurements are made of the permittivity in a heat set, nonwoven staple filament polypropylene as a function of the dissolved oxygen content (DOC) of the water. Vacuum deairing of the water to a DOC of 5 ppm or below insures that the measured permittivity will not be lowered by oxygen effects. Careful long-term measurements show that the measured permittivity is reduced very significantly if the ...

  • 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 ...

  • Cylindrical Expansion Test for Tensile Properties of Geotextiles

    This technical note describes a new apparatus and testing procedure to perform rapid quality control and assessment of the design parameters of geosynthetic materials. The cylindrical expansion test (CET) is based on the principles of the extension of a geosynthetic specimen wrapped around the surface of an expanding thin-wall cylinder. The parametric study conducted on two nonwoven polyolefin ...

  • 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 ...

  • A Thickness Equation for Nonwoven, Needle-Punched Geotextiles under Normal Loading

    An equation to predict the thickness of nonwoven, needle-punched geotextiles under normal compressive loading is proposed. The equation is t=(t0-t8)e-as+t8 in which, t0 is the initial thickness, t8 is a limiting thickness, s is the normal stress, and a is an empirical coefficient. Comparison with thickness data obtained in multiple tests on eight different geotextiles using an in-plane, radial ...

  • Using geotextile tubes for dewatering and beneficial use of high water content solid wastes: design charts and verifications

    The interest to push the beneficial use of high water content solid waste materials to a greater extent has increased tremendously. Using woven geotextile tubes as confinement and dewatering facilities for industrial, municipal sludges, and dredged materials offers various advantages to expand and enhance existing beneficial use strategies. To be successful, proper design of geotextile tubes is ...

  • In-Plane Air Flow Through Needle-Punched, Nonwoven Geotextiles Under Normal Loading

    Knowledge of the in-plane permeability of nonwoven geotextiles to air and other gases has important applications including, for example, the transport and collection of methane gas beneath landfill caps. The results of in-plane flow measurements of air through eight different needle-punched, nonwoven geotextiles are presented. Air flow was measured using a radial flow device under a range of ...

  • Equipping a once-fatal highway to deliver solid future performance

    Background Stretching 1189 miles along the southeastern coast from Virginia to Florida, the Ocean Highway (US 17) mixes magnifi cent scenery with unpredictable driving conditions. In 2005, the South Carolina Department of Transportation (SCDOT) called its 211-mile stretch of US 17 one of the deadliest roads in the nation; and between 1997 and 2005, the highway experienced nearly 1,000 ...

  • Millstone Manor Parking Lot Stabilization - Case Study

    Shallow utilities won’t get in the way of our high strength woven geotextile’s ability to stabilize this parking lot. Millstone Manor, an apartment complex located right next to the Ogden River at the base of the Wasatch Mountains, had been having difficulty stabilizing their parking areas for years. Due to its proximity to a water source and resulting soil types, the CBR ...

  • Using Geosynthetics in Slope Stability

    The majority of slope failures within the geosynthetics industry can often be avoided with proper engineering and material selection. However, the factors that affect slope stability can be difficult to discern and measure. Soil thickness, seepage forces, seismic forces, gas uplift, geomembrane texturing, engineering and provision of reinforcing elements are only a few of the factors affecting ...

  • Geotex® 200ST Fabric brings smooth travel to remote road case study

    Willow Creek Road is a 36-mile stretch of un-paved road. Cattle ranchers, vacationers and hunters use the road, but during wet weather it became a muddy, hazardous mess. The soil is a silty clay, and earlier attempts to use just gravel were less than successful. In addition, the nearest gravel pit is a three-hour drive, so Valley County Road Superintendent Wayne Waarvik knew he had to do more ...

  • Geosynthetic/Soil Interface Friction Angles Using a Rotation Shear Device

    A modified rotation shear device was used for measuring interface friction angles between soils and geosynthetics. The device was modified so that a geosynthetic specimen can be attached to the upper platen. A reliable method for cutting and attaching geosynthetic specimens to the device is described. The geosynthetic mounting system is simple, strong, and easy to remove. Interface friction ...
