Ground Improvement
Ground improvement techniques are methods used by the geotechnical engineer for 'fixing' the problems of poor soil to increase its bearing capacity, reduce settlements and the time in which it occurs, retard seepage, accelerate the rate of drainage, increase the stability of slopes, mitigate the liquefaction potential in seismic prone areas, etc.

L&T GeoStructure offers `Design & Build' innovative and value engineered ground improvement solutions that may be used in a broad construction spectrum from industrial, commercial and housing projects to infrastructure construction such as dams, tunnels, ports, roadways and embankments.

Soil and Rock anchors provide an effective alternative to large gravity or stabilization structures. Anchors are designed to withstand lateral and uplift forces hence are typically used with temporary and permanent excavation support systems, as a part of permanent retaining walls, for dam stabilization, or to resist wind-produced uplift forces.

L&T GeoStructure is a 'Design & Build' specialty geotechnical contractor offering expertise in anchors which can be installed at any angle from the vertical to the horizontal that could be pre-stressed or passive, depending on requirement.

  • Temporary & Permanent Anchors
  • Soil nailing
  • Rock bolts
