GPR Survey — Gurugram
GPR Survey on Sohna Road, Gurugram — Underground Utility Detection
A corridor that filled up faster than anyone could record it — and that floods, which tells you a good deal about what is happening underground.
Owned fleet only: 1.5 lakh+ km delivered, 100 km a day peak output and a best month of 700 KM in 30 days. Because this location falls within Delhi NCR where our crews are based, there is no minimum order value. Beyond NCR a ₹1,00,000 per-project floor covers rig and crew movement from Faridabad.
Quick AnswerMezux Touch runs GPR survey along the Sohna Road corridor — the Sectors 47 to 49 belt, the commercial and IT parks, the residential developments and the approaches toward Vatika Chowk and Badshahpur. Rapid unrecorded development and drainage failure define the survey problem here.
Development outpaced the record
This corridor filled in roughly a decade, with individual developers servicing their own parcels on their own timelines and connecting to trunk infrastructure as and when it became available.
Nobody was consolidating any of it. The corporation inherited responsibility for roads and drainage without inheriting reliable drawings of what had been laid beneath them, and developers who completed and left took their as-builts with them.
Survey here is therefore discovery, and we plan line spacing on that basis rather than treating any existing drawing as a starting hypothesis.
Waterlogging is a subsurface symptom
The corridor's flooding history is well known locally, and from a survey point of view it is diagnostic. Standing water indicates drainage that is undersized, blocked, mis-levelled or discharging into something that no longer flows.
Depth profiling along a storm drain frequently explains a flooding complaint that surface inspection could not — a run that has settled and lost its fall, or a connection into a line that was later built over.
We report drainage levels along the alignment as a distinct output, because on this corridor that profile is often the finding the client actually acts on.
Why a level survey beats a camera here
A CCTV survey shows the inside of a pipe. It does not show whether that pipe still runs downhill. On a corridor where drainage was laid by several developers to several datums, the fall is the question worth answering.
Radar gives continuous invert depth along the run, which is what reveals a section that has settled, a connection made at the wrong level, or a length laid against the intended gradient. Those are the causes a camera cannot diagnose.
We issue the drainage level profile as its own drawing, because on this corridor it is usually the document the client acts on rather than the utility plan.
Commercial parks and their private servicing
The office and retail developments along the corridor hold their own internal distribution behind their boundaries, with facility teams rather than the corporation holding whatever records exist.
Connectivity into these buildings involves crossing from public road into private land, and the internal routing question is generally harder than the corridor approach.
The widened carriageway and its edges
Road widening along parts of the corridor moved the carriageway edge over ground that previously held utilities laid to a different alignment. Services that were once in a verge are now under running traffic.
Cover over those stretches is frequently less than specification, and we record it continuously rather than sampling, because on a widened road the variation between points is the finding.
Programming around traffic and season
Peak-hour traffic on the corridor makes daytime working impractical on the main carriageway, so most execution runs in night windows with traffic management.
Monsoon months are avoided where a programme allows, both because saturated ground reduces achievable radar depth and because the corridor's drainage behaviour makes site conditions unpredictable.

Frequently asked questions
Because the corridor filled in about a decade with each developer servicing its own parcel on its own timeline. The corporation inherited the roads without inheriting reliable records of what was laid beneath them.
Often, yes. Depth profiling along a storm drain reveals runs that have settled and lost their fall, or connections into lines later built over — causes surface inspection cannot find.
Regularly. Repeated saturation with overloaded drainage moves fines out of the soil, and the resulting cavities are reported separately because a void under a carriageway is a structural risk, not a utility position.
Yes, and it is a specific hazard here. Lines once in a verge now run under traffic, frequently with less cover than specification, so we record cover continuously rather than sampling.
Outside the monsoon where the programme allows. Saturated ground reduces achievable radar depth and the corridor's drainage behaviour makes site conditions unpredictable during those months.
There is none. Sohna Road is inside NCR and close to our Faridabad base, so short diagnostic surveys on a single stretch are routine work. Outside NCR a Rs 1,00,000 per-project minimum applies.
We have pushed to 100 km a day on unobstructed corridors, using night working and company-owned radar systems. Across one 30-day period we have recorded 700 KM completed. Our running total stands beyond 1.5 lakh km of GPR survey delivered. What your own route achieves depends on congestion, access and the deliverable specified.
Sohna Road drainage that will not clear?
Give us the affected stretch and we will profile the invert levels along it, which is where the answer normally is.

Our Sohna Road crews survey through Gurugram alluvium under rapid developer-placed fill, with drainage laid to inconsistent levels. On that ground the depth we can usefully reach is typically 2.5 to 3.5 metres, reduced where repeated saturation has disturbed the ground. The depth ceiling is the honest constraint here; coverage rate is a secondary concern. If your design needs confidence below that ceiling, we recommend complementary locating or trial holes at scoping stage instead of delivering an inconclusive drawing afterwards.
How the survey is run here
How closely we run the lines in Sohna Road follows the material, not a fixed template. Cross-coverage tightens in any material capable of producing its own strong reflections. Velocity is re-established wherever the material changes, so a depth quoted at one chainage means the same as a depth quoted at another. Everything is delivered by our own crews on our own equipment, so a start date is a commitment rather than a forecast.
What you receive
Layered DWG drawings set out in your own convention, each service on a separate layer with depth, method and confidence attached as attributes. Spatial output as SHP or KML on request, plus a PDF set sized for site circulation. A signed survey report stating coverage achieved, achievable depth by section, areas of no access and every limitation encountered. On Sohna Road work the report also records the authorities involved — MCG, GMDA, the developers' estate teams on private parcels, the power utility — because the deliverable has to satisfy whichever of them receives it. Raw traces are stored indefinitely, which is what allows a finding to be defended rather than merely asserted.
Beyond the basics
Why are there so few usable drawings? Because the corridor filled in about a decade with each developer servicing its own parcel, and the corporation inherited roads without records.
Can a survey explain the flooding? Often. Depth profiling along a storm drain reveals settled runs and connections made at the wrong level, which a camera cannot diagnose.
Do you find voids under the road? Regularly. Repeated saturation with overloaded drainage moves fines out, and the cavity is a structural risk rather than a utility position.
Has road widening moved services? Yes. Lines once in a verge now run under traffic, frequently with less cover than specification.
How is a quotation actually built? From line spacing, access conditions, deliverable format and the confidence level you need. A per-kilometre figure without those four stated means very little.
Terms used on this page
Invert level — the inside bottom of a drain, which determines whether it still runs downhill. Loss of fines — the washing out of small soil particles by water movement, leaving a cavity behind. Level profile — a continuous record of invert depth along a drain, which reveals lost fall that spot checks miss. Trial hole — a small hand-dug or vacuum excavation used to confirm a detected feature physically. Electromagnetic locating — a complementary method that traces conductive services by their signal, used where radar alone cannot resolve them.
