With a ten-year background in
cementitious and chemical
grouting, Richard M. Berry incorporated Rembco in
1982.
The initial geotechnical service was strengthening low density
and water saturated soils by compacting them with grout. This
grouting application opened topographical sites that were
previously unsuitable for development.
Shortly afterwards, Rembco initiated the use of compaction
piles as supports for settling foundations, as columns from which foundations could be lifted, and as a means of leveling
slabs, patios, and sidewalks.
During the next two years, Rembco led the grouting industry
in compaction pile technology as an economical and safe
means to support excavated walls of construction sites. This
system is installed prior to the contractor's excavation, and
it allows the contractor to completely excavate without
the delays of conventional shoring.
In 1985, chemical grouting was added to the list
of services. These grout materials include acrylics, acrylamides, epoxies, and polyurethanes. This technology is also suitable
for "in situ" applications where the
customer's operations must continue undisturbed. Chemical grouting is used to seal leaks in pipes,
dams, mine shafts, walls, tunnels, and other structures. It
is also used to encapsulate select areas in soils that have
been contaminated with PCBs, mercury, and other toxic
substances.
Rock anchors and rock bolts were the next services
brought onboard in
1988. These anchors are used to secure fragmented stratums in
mines, steep slopes, and vertical cuts, provide anchorages
for foundations, and tie downs for
structures with high wind loads or
those built underwater which experience up-lift pressures.
Rembco has installed rock anchors that individually have
1,000,000 pounds of tested capacity.
The Company initiated soil nailing in 1989.
Rembco was one of the first companies in the US to stabilize
slopes using the soil nailing system. The system is a
method of securing unstable earth to underlying stable
soils. The protruding portions of the nails are
systematically covered with
wire mesh, bars, and plates. A facing of shotcrete is then
applied to secure the construction area from the top down,
lift-by-lift.
In 1992, Clay Griffin joined the Company to
refine existing services and expand them by adding drilled micropile and minipile foundations.
These are used to transfer structural loads to deep bearing
strata
where overlying soils will not support designed structural
loads.
Sinkhole remediation was the next service offered.
The ground fault is corrected after determining drilling
depth needed, grid pattern, injection rate, volume and pressure
needed, and proper grout mix. We have successfully closed
sinkholes under railroads, waste water treatment plants,
streets and highways, parking lots, and various structures.
Admixture technology has played a prominent role
in the improvement of specialty grouting at Rembco.
These additives are used to enable and enhance particular
properties of the grout for very specific applications.
Our understanding of grouting objectives and the medium
to be injected help us determine the optimal properties
of the grout. Set time, viscosity, thixotropy, unit
weight, compressive strength, and colloidal stability
are all functions of mix design, and are optimized for
each application.
Rembco began purchasing major pieces
of equipment in 1996 to expand its ability to do larger geotechnical
jobs. The equipment included crawler-style drill rigs,
mobile grout pumps, automated mixing plants, volumetric
grout-mixer, and single-pass drill and grout rigging. From that point,
Rembco had the
capability of successfully
competing for jobs above $1,000,000.
Eccentric downhole casing systems were brought onboard in 2001. These systems greatly increase the speed
of rock
drilling and
provide a cleaner bonding area for the grout in bedrock
sockets. They are especially useful in installing minipiles and
rock anchors.
