One-stOP
differentiates us
A first in India! L&T GeoStructure successfully executed piles of diameter 2500mm and depth of 33m in very hard rock strata at Chennai Metro Rail site. These large diameter piles contribute significantly to time and cost savings, thereby creating value for the customer.
L&T GeoStructure has successfully completed diaphragm wall panels using trench cutters for depths varying from 25 – 30m at metro and commercial projects across India.
We are one of the pioneers of the top-down construction method. This has the advantage of simultaneous working both above and below ground, thus resulting in significant time savings, thereby unlocking value.
L&T GeoStructure has successfully executed ground improvement solutions on `design and build’ basis for various high-rise structures across India. We offer a combination of piles and stone columns to avoid liquefaction.
We possess the expertise and equipment to drill in very hard strata where uniaxial compressive strength is greater than 100 MPa. This exploration in challenging geotechnical strata calls for innovative engineering techniques.
Our in-house high-end design team provides unique and cost-effective solutions, and is known for their technical expertise by their paper presentations in various ground engineering seminars across the world. We use in-house developed high-end software applications for in-depth analysis of various ground engineering issues, to recommend optimal solutions.
