geotechnical Applications

  • Geotechnical Applications

    Pore pressure variability and control is one of the most significant aspects of Geotechnical Engineering practice related to slope stability, underground openings, foundation of heavy structures, and water retention facilities. Pore pressure effects are most often controlled by natural small-scale hydrogeologic details. Characterization and management of pore pressures requires closely-arrayed repeated measurements to determine the effects of these details for design of appropriate mitigation measures, for performance monitoring and control of the selected mitigation measure. Since the late 1970’s the Westbay System has been used on some of the largest landslide studies in the world.

    Geotextile provides inherently stronger track system that lasts longer, requires little maintenance, and produces a net cost savings. For new track or repairs, there's no need to remove native soil, install our product directly on the subgrade and eliminate contamination from below the ballast.

    The product produced by our firm helps to strengthen the paved surfaces by setting up a separation barrier between subsoil and base, permitting free water to drain quickly, but preventing soils from moving into the base. The fabric adds tensile reinforcement to the pavement permitting heavier wheel loads while substantially reducing maintenance. It also provides a long lasting, better quality surface while allowing a 25 per cent reduction in base course aggregate.

  • Tunnels

    The geotextile performs two primary functions when used in the construction of tunnels:- 1. Protection of the linear from abrasion and puncture by protrusions from the base surface of the tunnel well. 2.Drainage of water seeping through the rock and sprayed concrete layer. The in-plane oermeability of the geotextile enables the water to flow to a subsurface drainage collection system. where it is directed awa from the tunne

  • Geotechnical Monitoring Systems for Health Monitoring

    The management of a geotechnical project requires a wide range of important information coming from the sensors, which are of vital importance for correct execution of construction plans and to refine soil models.

  • Dewatering trenches

    Our articles are designed to allow liquids to pass in the draining systems as in the micro pore tubes and at the same time help to retain the finer particles while avoiding their migration into the drainage.

  • Water Containment

    Polymeric liners are prone to puncture by inclusions within the underlying soil. Thick, non-woven geotextile can be used to give protection to liners during installation. Often the upper slopes are exposed to damage and it is a good practice to cover these areas with a depth of soil which will sustain vegetation. Alternatively, a stone or concrete substance can be used to achieve a hard landscaped appearance. Our product will protect the liner from puncture whilst also providing a degree of slope stability.

  • Water-blocking geotextiles

    SAF is the key component for a range of geosynthetic membrane fabric technologies – which can be adapted into a wide range of formats – that are used by many industries requiring water-sealant solutions. Such fabrics are designed to act as a barrier to water and help alleviate the problems of flooding. As a fibrous super absorbent it allows for ease of handling, giving rise to exceptionally substantive and even distribution profiles within final fabric construction. As such, geosynthetic membrane fabrics incorporating this technology offer truly unparalleled levels of waterblocking performance. These fabrics have the ability to separate, filter, reinforce, protect and/or drain, and offer many advantages that are extremely important to demanding civil engineering projects. The fact that they can be supplied in rolls is also a huge benefit when being used on large-scale projects.

  • Soil Stabilization

    Problem: Poor load-bearing soils pose a significant problem for transportation and construction needs. Unpaved areas, such as access roads, paths, parking lots, driveways, etc can be highly vulnerable to near-surface shear failure and rutting, especially in moist conditions or areas with higher expected loads. Typically, engineers bridge over weak soils with rigid structures such as thick, reinforced concrete for roads and highways. However, such techniques are prohibitively expensive and inordinately difficult to install. The poorer the quality of the sub-base and the heavier the expected loads, the greater the amount and better the quality of support required.
