Our Major Activities Are
01. Rectifications of concrete structures
We identity the major problems in the structure and then Rectify them. We use various construction chemicals and powers tools etc. Diagnostic work is done by means of NDT or destructive testing as per requirements.02. Water Proofing
All type of Roof terrace, bath room slabs, basement etc. is done by using chemicals and/ or polymer modified bituminous membrane by torch on method.03. Pressure Grouting
It is applied for defective concrete or hony comb, Both simultaneously and epoxy grouting work for basement floors or any other concrete walls.04.Fixing Rebar
We also do rebar fixing work to fix bars up to 40 mm diameter. As well as the reinforcement bars on existing concrete surface by using fisher chemical.05. Treatments of expansion joints.
For irregular high movement joints we use mostly Polyurethane Sealants or Hypalon flexible sheeting.06.Finishing of concrete surface using power tools.
We use efficient method fast, economical for working on concrete surface to achieve better finish.07.Soil Stabilisation
METHODOLOGY OF GROUND
IMPROVEMENT BY CHEMICAL GROUTING WORK:
I. Scope
of Work:
Grouting
work with special chemical shall be carried out about 1.5.0 M C/C up to a
desired depth (Exact depth will be finalised by Prof Amberish Ghosh) from
existing ground level for ground improvement
II. Equipment
and Accessories:
The following equipments and accessories shall be required for Chemical Grouting work
II.I Boring Equipment
Boring
rig with tripod and accessories for sinking bore holes like rotating shaft with
gear.
II.II
Others equipment and accessories:
Inflatable
packers, grout material preparation tank, electrically operated grout mixture,
hand operated grout pump etc.
III. Boring of Rotary mechanical drillers
The
borehole of approximate dia 70 mm is formed by drilling into the ground with
Mechanical Rotary Driller and wash boring process to the required depth or
degree of resistance. Casing may be required. On reaching of the desired depth,
the pilot driller will be withdrawn and Inflatable packers will be lowered
immediately into the hole. Chemical
grout mix is then pumped through the
Inflatable packers.
IV. Grouting Methodology:
A
suitable, homogeneous, net
chemical grout material shall be
prepared in
a designed tank.
The prepared grout material shall not contain lumps or any other evidence of poor
or incomplete mixing.
The pressure pump shall
be
equipped with
a pressure gauge to monitor grout pressure. The grouting equipment shall be sized
to enable the grout to be
pumped in
one continuous operation.
The compressed air may be utilized directly to pressurize the
grout material to ensure the
percolation of the grout material through the voids of the
subsoil strata.
At the time of grouting the top
of the
pipe shall
be properly plugged so that the grout materials cannot come out
from
the hole. Grouting operation will cut off when refusal
pressure of the slurry will reach not less than 1.5 kg/cm2 and/or slurry will oozes out from nearby holes
V. Improvement of Ground:
The improvement
in the ground capacity in respect to soil stabilisation may be measured by conducting soil investing work before and after soil grouting. Once the
grout cures, the
porous soils is transformed into a near solid mass
and
bore holes full of chemical slurry will act as soil nails or a column of treated soils. The treated subsoil layers shall have a much
lower
hydraulic conductivity, higher shear strength and shall be stronger and less compressible than before.
