Ground Penetrating Radar Unearths Subsurface
Obstructions
Ground penetrating radar is an example of
how cutting-edge technology can simplify the
job once considered a next to impossible
chore. When it comes to detecting what exactly
lies within the surface of dry sandy soils or
massive dry materials like concrete or limestone,
Ground Penetrating Radar or GPR uses high
frequency wave pulse in the form of
electromagnetic energy that is shot into the
subsurface of the target material. The working
principle of this technology is exactly the same
as an aerial radar. The GPR antennae uses a
certain frequency, and puts out wave-pulses into
the ground or concrete to measure its depth or
inherent subsurface items or obstructions.
GPR can locate underground utilities, pipes,
conduit, void, water intrusion, pt tendons, rebar
and more. It can even assess concrete. Why
GPR? Concrete scanning using GPR ensures
that the work is done efficiently without
rendering any safety related threats to the
professionals. Back to the days of 1980s, this
technology made its headway into detection of
subsurface objects. Professionals relied on it
for its efficacy of measuring up the depth of a
concrete slab or to detect the exact condition of
buried object. It is not an exaggeration if
we say GPR has changed the definition of
locating utilities or gauging the depth of a
buried object. Imagine if the construction
engineer declares that the property cant be used
for building a home because of certain
issue related to its subsurface as detected
by GPR. Countless amount of labor-and
intensive works involved into digging or drilling
the surface would be averted, thus saving the
owner from considerably expense on labor costs
and damages. Instead of blindly drilling or
coring to find out that your contractor cut
through a conduit or utility line,, ground
penetrating radar makes the job much
simpler for professionals. Utilizing GPR
will avoid unnecessary risks and expensive
delays. The main purpose of GPR is to help the
client to be informed of subsurface items that
are not detectable by visual means. In addition,
GPR can assess the quality of a concrete slab
(frail or sturdy) to get an idea whether the
subsurface ground may possibly collapse under a
load, such as in the condition when it has
cracks, voids or deteriorated rebar. GPR uses
high frequency or typically polarised
electromagnetic wave that is harmless and a non-
destructive way to avoid possible damages and
assist in planning. In concrete scanning with
ground penetrating radar, the GPR technology
helps trained technicians to locate rebar and
post tension cables or other buried materials in
order to ensure safe and efficient drilling,
thereby preserving the integrity of the survey
site as well helping the clients to conduct core
drilling without mishaps. Underlying obstructions
beneath a concrete slab, if undetected, can pose
a risk of potential damage. With GPR technology,
the location and depth of such risks can easily
be detected, thus allowing for safer
construction. GPR is an effective way of finding
location and depth of subsurface objects to make
sure you understand if they are risky or safe so
that work can proceed safely, without inviting
any danger. For more information please visit
