differentiates us
Hard rock boring
Diaphragm walls using trench
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.
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.
Large diameter piling
Top-down construction method
Ground improvement
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.
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.

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.

over competitors.
Large diameter piling
2500mm dia pile at CMRL, Chennai
This is a unique niche area, and
we are experts in the design and
execution of large diameter piles –
ranging from 1200mm to 2700mm
diameter. These large diameter piles
have huge advantages in terms of
savings in time and cost.
