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.

    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

    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.

  • Geo Bags

    Geo Bags have the following advantages : -Affordable price with global standard specification -Available Ex-stock or fastest delivery, avoid blockage of money against container load Staggered delivery for sizable quantity acceptable. -In compare to conventional erosion protection work using C.C. Block, gravel, hard rock etc, sand filled geobags technology involves less cost. -World widely it has been seen that erosion protection work using Geo bags requires less installation and maintenance cost light weight equipment, less space for construction works, transportation cost, less energy requirement. -The constructing materials like sand of geo bag are locally available and cost-effective compared to importing boulders from other countries. -The manufacturing of geo bags and quality control of the bags are easy compared to the C.C. blocks and boulders.

  • Channel Wall Protection

    Problem: Channels are oftentimes subject to debilitating erosion due to the water contained by the channel walls. Depending on the velocity of the water flow and the frequency and degree of stormwater runoff, severe hydraulic stresses upon the channel walls can pose significant dangers to the system.

  • Slope Erosion Control

    Problem: Soil particles are susceptible to being detached and carried away with concentrated runoff streams, forming rills and gullies that grow with time. The slope integrity is diminished, eroding the slope face and becoming a larger environmental and safety issue. Slopes steeper than the natural angle of repose for the slope materials require additional protection measures, as are slopes subject to more severe hydraulic stresses.

  • Shoreline reconstruction

    Watermaster technology is an excellent solution for reconstruction of shorelines in urban and suburban areas. You do not have to put up with a muddy, rocky or low water bottom. Watermaster Classic can deepen, build and clean out the shorelines. With this multipurpose technology the right solution for various problems can be chosen, so that the work is done cost effectively and properly. Reconstructions of shorelines, building quays and other tasks done by Watermaster save the nature and the work is done safely and effectively.

  • 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.

  • Retaining Wall Construction

    Problem: Retaining Wall structures are growing ever more necessary as construction is forced to deal with rough terrain, steep slopes, and embankment reinforcement. Changes-in-grade present obstacles for roads and other development requiring flatter, more usable land. Most current types of retaining walls are made of cast-in-place, steel-reinforced concrete walls whose virtue is based entirely upon its internal strength and rigidity. However, these cantilever walls are expensive, vulnerable to cracking from high stress situations, and unattractive in the environment.
