GPR Survey in Navi Mumbai — Underground Utility Detection & Mapping
A planned city where the node drawings genuinely exist, wrapped around a container port and an airport site — three very different survey problems within one jurisdiction.
Since 2003 we have surveyed over 1.5 lakh km by radar, held 100 km a day at peak and delivered 700 KM inside 30 days without hiring a single system. Because mobilisation runs from Faridabad, sites beyond Delhi NCR carry a ₹1,00,000 per-project minimum. Inside NCR no minimum applies.
Quick AnswerMezux Touch runs Ground Penetrating Radar survey across Navi Mumbai — the CIDCO nodes from Vashi to Kharghar and Panvel, the JNPT port and its approach corridors, the Taloja industrial area and the airport influence zone. Planned nodes, reclaimed belts and heavy port servicing each need different assumptions. Scope covers OFC and enterprise routing, industrial surveys, civic mapping and pre-crossing verification.
A planned city, node by node
Navi Mumbai was developed node by node with designed servicing, and the development authority's layout drawings are a genuinely useful starting position — unusual in Indian practice and worth using properly.
The caution is the familiar one. Nodes developed decades apart have had connections, upgrades and telecom overlay added since, and very little of that returned to the original set. Older nodes have drifted considerably further than newer ones.
So survey here is reconciliation rather than discovery, and we report where the ground and the drawing disagree instead of quietly adopting whichever is tidier.
Reclaimed belts and creek margins
Substantial parts of the city sit on reclaimed ground along creek margins. That fill is saline, retains moisture and behaves inconsistently along its length, and both salinity and moisture reduce achievable radar depth.
Calibration follows the ground actually present rather than one assumed velocity across a route. Where a section crosses from natural ground onto fill, the report says so, because the confidence carried either side is not the same.
Port and freight corridors
The container port and its approach corridors carry servicing sized for heavy cargo movement, along with pavement construction far deeper than an ordinary road. Radar behaviour over heavy pavement differs, and traffic makes daytime working largely unavailable.
Port areas run on permit and escort systems with their own security requirements, and survey windows are set by cargo movement. We arrange clearance ahead of mobilisation rather than at the gate.
Taloja and the airport influence zone
The Taloja industrial area carries chemical, pharmaceutical and engineering units with heavy power distribution, process water and effluent conveyance, much of it privately laid. Probable effluent lines are reported as their own category.
Around the airport site, construction and infrastructure work has rearranged ground extensively, and survey data has a shorter useful life there than elsewhere. We date every issue prominently for that reason.
Sectors that call us in here
Logistics and warehousing leads given the port role — plot surveys before slab and rack foundations on large sites. Enterprise and data-centre connectivity follows, with diverse-path verification a recurring request.
Industrial work at Taloja, civic schemes across the nodes, and construction surveys in the airport influence zone make up the rest.
Approvals and deliverables
Work can involve the municipal corporation, the development authority across its nodes, the port authority, MIDC at Taloja, the state public works department and the metro authority. Jurisdiction is mapped before drafting.
Output is layered CAD with depth annotation, GIS files where kept, a PDF issue set, and a report distinguishing what was confirmed against existing node drawings from what was found without them.
What we need to quote accurately
Tell us the node, whether the site sits inside a port or airport controlled area, and whether any part crosses reclaimed ground. Those three answers change clearance lead time, achievable depth and coverage rate together.
Where the development authority holds layout drawings for the node, we obtain them as part of records research and report against them, so you can see plainly where the built ground has drifted from the design.
What the report tells you
The deliverable distinguishes what was confirmed against existing node layout drawings from what was found without them. That distinction is genuinely useful here, because the development authority's records are good enough to be worth reconciling against rather than ignoring.
Where a route crosses onto reclaimed creek-margin ground, the change is marked and the achievable depth restated, since confidence is not comparable either side of it.
Port and airport-area sections carry their own dating, because ground there is being rearranged and a drawing's useful life is shorter than elsewhere in the city.
What our own fleet has actually delivered
Twenty-two years of subsurface work adds to this figure — corridor survey, plot clearance, civic mapping and plant scanning across 28+ States/UTs.
Peak sustained daily output on open corridors running day and night shifts on our own fleet. Planned CIDCO layouts and orderly roads allow good progress, with reclaimed stretches needing calibration along their length.
A full month at more than 23 kilometres a day, delivered without hiring in a single additional radar system.
Delivered on a separate programme in its own 30-day window, which is what makes the pace a rate rather than an anecdote.
Owned outright, maintained in-house and crewed by our own operators from first mobilisation to demobilisation.
More than two decades of underground work, certified across quality, environment and occupational health and safety.
Frequently asked questions
Because they describe the nodes as designed and first built. Connections, upgrades and telecom overlay since have not all returned to that set, and older nodes have drifted considerably. We reconcile the record against the ground.
Yes. Creek-margin fill is saline and holds moisture, both of which absorb radar energy. Where a route crosses from natural ground onto fill, the report states the change because confidence is not the same either side.
Yes, under the permit, escort and security arrangements those areas require. Windows are set by cargo movement rather than daylight, and clearance is arranged before mobilisation.
Because construction and infrastructure work there is actively rearranging the ground. A drawing a year or two old may describe an arrangement that no longer exists, so we date every issue prominently.
Regularly. Chemical and pharmaceutical units carry privately laid process and effluent lines that were never consolidated, and those are flagged as a distinct category in the report.
Potentially several — municipal corporation, development authority, port authority, MIDC, state PWD and the metro authority. We establish jurisdiction before any application is drafted.
We have pushed to 100 km a day on unobstructed corridors, using night working and company-owned radar systems. Our fastest recorded delivery stands at 700 KM in a 30-day window. In total we have completed more than 1.5 lakh km of GPR survey. How fast we move on your job depends on how crowded the ground is and what the report has to prove.

Mezux Touch surveys Navi Mumbai through reclaimed ground over creek deposits, with rock on the higher CIDCO nodes, where achievable investigation depth is typically 2 to 3 metres, varying with how each node was reclaimed. It is the number worth agreeing before a rate, since it determines what the survey can and cannot settle. If your excavation passes that depth, verification rather than radar alone is the correct answer, and we say so before the work is booked.
How the survey is run here
How the grid is laid out in Navi Mumbai depends entirely on what the ground returns. In ground that produces its own reflections, tighter cross-lines are what stop a false find reaching the drawing. Velocity is re-established wherever the material changes, so a depth quoted at one chainage means the same as a depth quoted at another. Company equipment and company staff throughout, so no part of the programme sits with a third party.
What you receive
A layered CAD issue in DWG matching your standard, where each detected line carries its depth, how it was detected and how far it can be relied on. For spatial databases we issue SHP or KML alongside the CAD, with a PDF set for distribution to site. A signed report setting out coverage achieved, section depths, access refusals and every limitation that bears on the drawing. On Navi Mumbai work the report also records the authorities involved — NMMC, CIDCO on node land, the port authority at JNPT, MSRDC on arterials — 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
Do the CIDCO layouts help? Genuinely, for trunk services. The nodes were planned and the layouts retained, so the work is reconciliation rather than discovery.
What changes near the creeks? Achievable depth falls in saturated deposits, and we state the figure by section rather than for the whole node.
Do you work at the port and its approaches? Yes, under port authority access and security process, separate from the municipal corporation.
Does node age affect the survey? Yes. Earlier nodes carry more accumulated servicing than recently developed ones, and we calibrate by area.
Can the survey be phased across a programme? Yes, and on long corridors it usually should be. Surveying immediately ahead of each construction front gives fresher data than one pass months in advance.
Terms used on this page
Node — a planned CIDCO sector developed as a unit with services designed into the layout. Creek deposit — soft saturated material laid in a tidal inlet, limiting radar depth. Reclamation fill — imported material placed over former water, variable in composition along its length. Confidence grade — a stated reliability level attached to each detected feature rather than a blanket claim across the drawing. Antenna frequency — the radar frequency used; higher frequencies resolve small shallow targets, lower frequencies reach depth.
