  • Solidification/Stabilization

    Introduction: As for in situ solidification/stabilization (S/S), ex situ S/S contaminants are physically bound or enclosed within a stabilized mass (solidification), or chemical reactions are induced between the stabilizing agent and contaminants to reduce their mobility (stabilization). Ex situ S/S, however, typically requires disposal of the resultant materials. Under CERCLA material can be ...

  • The Geoweb Soil stabilization system - Case Study

    The GEOWEB® system is a proven technology for solving challenging soil stabilization problems common in the railroad industry. Railway engineers worldwide have successfully applied the GEOWEB® cellular confinement technology to 1) provide a high-stiffness roadbed foundation at grade under track, crossings and turnouts, particularly in areas of weak soils, 2) eliminate deterioration from ...

  • In-situ stabilization using Shallow Soil Mixing and Deep Soil Mixing

    Of the currently emerging technologies for site remediation, one of the most attractive and economical is in-situ stabilization and/or in-situ fixation of contaminated soils by Shallow Soil Mixing (SSM) or Deep Soil Mixing (DSM). Actually, the soil mixing process is not new. It has been in use as a geotechnical construction process for over two decades. However, its use as a treatment for ...

  • Boulder Concrete Cloth Erosion Repair

    Concrete Cloth provides an affordable solution for an eroded hard-to-access residential slope. After a period of heavy rainfall, a Boulder, Colorado, homeowner discovered severe erosion in his backyard at the end of his leach field (also known as a septic drain field). He had to find a way to repair this damage and stop it from happening again; nearly half of his lawn had dropped three ...

  • Articulated Concrete Blocks Provide Much Needed Protection for Your Pipeline

    One of the many ways that articulated concrete blocks can protect pipelines is by adding structural stability in areas that are particularly prone to erosion. This erosion is not the only type of hazard posed to your pipeline, though, and if you don’t have the proper protection in place, your pipeline could be susceptible to deterioration at the hands of these other threats as well: ...

  • 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 ...

  • In Situ Solidification/Stabilization

    Introduction Solidification/stabilization (S/S) reduces the mobility of hazardous substances and contaminants in the environment through both physical and chemical means. Unlike other remedial technologies, S/S seeks to trap or immobilize contaminants within their 'host' medium (i.e., the soil, sand, and/or building materials that contain them), instead of removing them through chemical or ...

  • Occurrence and dissipation of benzotriazoles and benzotriazole ultraviolet stabilizers in biosolid‐amended soils

    Benzotriazoles (BTs) and benzotriazole ultraviolet stabilizers (BUVSs) are commonly used industrial and household chemicals, but little is known about their dissipation behavior in the soil environment associated with biosolid application. This study investigated the occurrence and dissipation of four BTs (BT, 5‐TT, CBT and XT) and five BUVSs (UV‐326, UV‐327, UV‐328, UV‐329 and UV‐P) in ...

  • Assessment of the Unconfined Compressive Strength of a Lime Stabilized Soil by an Abrasion Test

    Stabilization by lime, which is frequently carried out to improve the mechanical properties of soils, results from the formation and development of cementitious calcium silicate aluminate hydrate gel. The gel produces interlocking and bonding of the soil particles, hence increasing the strength and abrasion resistance. The proposed method to assess the compressive strength of the existing ...

  • Aggregate stability and erosion response to antecedent water content of a loess soil

    Soil erosion processes are affected by the erodibility of the soil and by the erosivity of the rain. The effects of rain characteristics and invariant soil properties such as texture and organic matter content on soil erosion processes are well documented. The effect of antecedent soil water content ({theta}a) on aggregate breakdown, seal formation, and subsequent soil erosion is much more ...

  • Rotational and cover crop determinants of soil structural stability and carbon in a potato system

    Understanding processes that ameliorate structural degradation in sandy soils is particularly important in intensively managed potato (Solanum tuberosum L.) systems. Seven 2-yr potato rotation systems were evaluated over 3 yr in an irrigated field trial comparing winter management systems bare (B) and cover crops: rye (Secale cereale L.; R), rye-hairy vetch (Vicia villosa Roth; RV) mixture and ...

  • Cypher Environmental Ltd. Environmentally Friendly Soil Stabilizer Introduced to the Dominican Republic

    Building effective and long lasting roads in the Dominican Republic has proven to be difficult in the past due to high annual rainfall, high temperatures and the soil type predominantly found on the island. Recently a demonstration was performed on a stretch of road at the Naco Golf & Country Club near Santo Domingo with EarthZyme, a 100% environmentally friendly soil stabilizer that is ...

  • The stability of the relative content ratios of Cu, Pb and Zn in soils and sediments

    The study indicates that the relative content ratios of Cu, Pb and Zn in soils and sediments tend to have stability compared to those in meteorites, rocks and organisms. This stability is considered to be associated with their geochemical properties and has no relationship to the existing environments if it is not disturbed by an anthropogenic factor. In addition, it can serve as a background ...

  • Cellular confinement system stabilizes poor soil base, Kent County, Michigan

    'One area that many counties struggle with in road construction is poor soils,” says Tom Byle, maintenance and local road construction engineer for the Kent County Road Commission, Kent County, Mich. “Many country roads in America were built over muck, swamps or other similar, inadequate soils. Most counties cannot justify the expense of the standard peatremoval treatment, digging the peat out ...

  • 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 ...

  • Stabilization of Liquefiable Samples During Transport

    This technical note presents a new method to transport liquefiable soils from the investigation site to the laboratory. The development of this method resulted from research on liquefiable soils from the Imperial Valley, CA. This method is based upon the application of a slight vacuum on the pore water of the soil. The vacuum decreases the pore pressure, and therefore increases the effective ...

  • Stability and environmental geochemical profile of toxic heavy metals in soils around a crude oil refinery

    Soil samples were taken near oil refinery activities, bulk and fractionated heavy metal contents, as well as other physico-chemical characteristics were measured. The reported results indicate that the enrichment factors of the measured heavy metals were 3.9, 1.8, 1.3, 23.7 and 52.5 for lead, nickel, zinc, cadmium and mercury, respectively. The samples can be considered to be extremely ...
