• OUR TECHNIQUES
• MENARD VACUUM CONSOLIDATION
The Menard Vacuum Method is a patented technology
that utilizes the isotropic atmospheric pressure to consolidate
saturated sedimentary soils using the same principles as the
classical preloading method.
The preload is applied by creating the Vacuum under
a membrane laid on the surface of the soft soil instead of
using classical surcharge by fill or sand..
• MENARD VERTICAL DRAINS
Because the strength of a soil increases
and its compressibility decreases with the decrease of water
content, one of the most successful method to consolidate
a soft saturated sedimentary soil is the vertical drains +
preloading method.
Menard Vertical Cylindrical Drains are patented
in South Korea.
• CMC COLUMNS
Stone columns and CMC Columns are both inclusion
methods. ( compacted gravel for stone columns and a compressible
cement-based grout for CMC ).
The CMC method ( Controlled-Modulus Columns
) is a patented technology allowing to get rid of the limitations
of the classical piling process : virtually no spoil ; length
of columns is considerably reduced thanks to a revolutionary
patented dimensionning concept ; shallow foundation of spread
footings and slab on grades is possible avoiding expensive
pile cap and stress-repartition beams.
• MENARD DYNAMIC CONSOLIDATION
Dynamic Consolidation ( or Dynamic Compaction
) is an economical soil improvement method consisting in transmitting
high energy shockwaves to a granular soil to improve its characteristics.
Practically, soil is compacted by mean of
impacts of a pounder ( 15 to 100 tons ) dropped from heavy
weight cranes ( 10 to 40m ) on the surface in a pre-designed
grid pattern.
• MENARD DYNAMIC REPLACEMENT
Menard Dynamic Replacement method has been
developed to cope with the limitations of the Dynamic Compaction
method which mainly covers granular type soils ( sand, ballast,
rockfill ) and landfills.
Improvement of the mechanical properties
of a sedimentary soil is achieved by repetition of high energy
impacts in a grid pattern.
The prints are filled with a granular material
which is pushed and compacted by the repetition of impacts
to create large diameter columns of highly compacted granular
material.
• ACTIVE CONFINEMENT TECHNOLOGY
Active Confinement Technology is a patented
method which permits to confine pollution within a limited
area as well as controlling and eventually reducing the pollutant
content within this area in order to rehabilitate the site
for safe further utilization and development ( industrial
complexes, recreational landscaping... )
• MENARD PRESSUREMETER TEST
Pressuremeter Test ( PMT ) developed by
Mr Louis Menard in the 50's, is so far the most accurate testing
method available for any kind of soils., It permits to get
deformation properties ( for settlement calculation ) through
a pressuremeter modulus as well as rupture or limit resistance
( for failure and bearing capacity calculation ) through a
limit pressure with a single test
