Purpose and Choice of Instrumentation
Purpose of Geotechnical Instrumentation
Site Investigation Instruments are used to characterize initial site conditions. Common
parameters of interest in a site investigation are pore-water pressure,
permeability of the soil, and slope stability.
Design Verification Instruments are used to verify design assumptions and to check that
performance is as predicted. Instrument data from the initial phase
of a project may reveal the need (or the opportunity) to modify the
design in later phases.
Construction Control Instruments are used to monitor the effects of construction. Instru-
ment data can help the engineer determine how fast construction can
proceed without the risk of failure.
Quality Control Instrumentation can be used both to enforce the quality of workman-
ship on a project and to document that work was done to
specifications.
Safety Instruments can provide early warning of impending failures, allow-
ing time for safe evacuation of the area and time to implement reme-
dial action. Safety monitoring requires quick retrieval, processing,
and presentation of data, so that decisions can be made promptly.
Legal Protection Instrument data can provide evidence for a legal defense of design-
ers and contractors should owners of adjacent properties claim that
construction has caused damage.
Performance Instruments are used to monitor the in-service performance of a
structure. For example, monitoring parameters such as leakage,
pore-water pressure, and deformation can provide an indication of
the performance of a dam. Monitoring loads on tiebacks or rock
bolts and movements within a slope can provide an indication of the
performance of a drainage system installed in a stabilized slope.
Rembco Geotechnical Contractors specializes in
slope stabilization,
soil nail wall,
foundation repair
and support,
grouting,
shoring,
micropile
construction,
rock drilling, and we remediate
sinkholes. We use a
problem-solving approach in the geotechnical portions of buildings, bridges, water plants, sewage plants, tunnels,
installing caisson bottom, and roads. We are experienced in these applications:
micro piles,
sinkhole repair,
permeation and
pressure

soil nails,
cement grouting,
chemical grouting,
micropiles,
compaction grouting, and
rock anchors.
Rembco techniques apply when adding new structures: especially
rock anchor,
microfine cement,
soil nailing, and
micropile
installations for foundation support. Our specialties are
soil nails,
rock anchor,
chemical and
compaction grouting,
mini piles,
