GPR Survey — West Delhi
GPR Survey in Paschim Vihar, West Delhi — Underground Utility Detection
A planned colony built over farmland — where the surprises beneath are older than the colony itself.
1.5 lakh kilometres and counting, a sustained ceiling of 100 km a day, and a record month of 700 KM in 30 days — every metre on our own equipment. 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 across Paschim Vihar — the planned residential blocks, the Rohtak Road commercial frontage, the institutional pockets and the approaches toward Peeragarhi and Nangloi. Agricultural infrastructure predating the colony is a recurring find here.
What was here before the colony
Paschim Vihar was developed over agricultural land within living memory, and the ground still holds what farming left: irrigation channels, field drains, boundary structures, open wells and abandoned borewells, all buried under the fill that levelled the site.
None of that appears on any colony drawing, because it predates the colony. Plot surveys before foundations find these regularly, and an old brick-lined well beneath a proposed footing is a genuine structural problem rather than a curiosity.
We report pre-colony features as their own category, separate from utilities, because they are neither owned by a utility nor recorded by anyone and they carry a different kind of risk.
Fill depth that varies block to block
Levelling the site meant importing fill, and the depth of that fill varies considerably depending on the original ground profile beneath each pocket. Made ground behaves quite differently from the natural alluvium below it.
For radar that means calibration has to follow the route rather than being fixed once. For excavation it means bearing conditions and trench stability change over short distances, which is worth knowing before shoring is designed.
The Rohtak Road frontage
The arterial frontage carries trunk servicing, heavy commercial vehicle traffic and dense retail and workshop activity, with servicing added as the strip commercialised.
Working there is night-only in practice, with traffic management, and productivity bears no relation to the quiet colony roads a few hundred metres away. We quote the two as separate lines.
Institutional pockets and school grounds
The colony includes a number of school and institutional plots with their own internal servicing laid over decades, held by the institution rather than by the corporation.
Playing fields and open grounds within them are unusually good survey ground — open, uncongested, no traffic — and they are frequently where an institution most needs a record, since nothing there is visible from the surface.
Filing and handover
Colony roads sit with the municipal corporation while the development authority retains an interest in the original pocket layouts, and Rohtak Road is PWD. Institutional plots approve internally through their own estate offices.
For construction clients the handover that matters is the foundation-relevant one: fill depth, pre-colony features and bearing-relevant observations, issued in a form a structural engineer can act on.
Civic clients take the standard CAD, GIS and PDF package with the utility schedule as the primary document.
Sectors that call us in here
Construction plot surveys lead, driven by redevelopment across the residential blocks where pre-colony features and variable fill both matter to foundation design.
Civic drainage and resurfacing work follows, with institutional campus surveys and commercial frontage connectivity making up the rest.
Numbers we can put a project name against
Access and coverage rates
The residential blocks are wide, low-traffic and workable through the day, so coverage here is among the better rates we achieve in West Delhi.
Institutional grounds are better still — open, uncongested and free of traffic. The Rohtak Road frontage is the only stretch needing night working.

Frequently asked questions
Irrigation channels, field drains, boundary structures, open wells and abandoned borewells, buried under the fill that levelled the site. An old brick-lined well under a proposed footing is a structural problem, not a curiosity.
Because made ground behaves differently from the natural alluvium beneath it. It changes radar calibration, and it changes bearing conditions and trench stability over short distances, which affects shoring design.
Yes, night-only with traffic management. Productivity there bears no relation to the quiet colony roads nearby, so the two are quoted as separate lines.
Yes, and they are unusually good survey ground — open, uncongested and traffic-free. They are also where an institution most needs a record, since nothing there is visible from the surface.
Three schedules: utilities, pre-colony features and fill depth along the alignment. Each answers a different question for a different reader.
There is none for Paschim Vihar. Sites inside Delhi NCR carry no order-value floor. Outside NCR the minimum is Rs 1,00,000 per project, set by mobilisation from Faridabad.
Peak sustained output on open corridors reaches up to 100 km a day, running day and night shifts on our own systems. Across one 30-day period we have recorded 700 KM completed. In total we have completed more than 1.5 lakh km of GPR survey. Actual pace on any given site is governed by utility density, access windows and the output format required.

Fill depth and old field structures both change the design — worth knowing before the drawings are frozen.

Paschim Vihar sits on Delhi alluvium beneath imported fill placed to level former agricultural land. Against that material, achievable depth is typically 2.5 to 3.5 metres, varying with fill depth between blocks. How far the radar reaches decides the value of the survey far more than how fast the crew moves. Beyond that range we recommend complementary methods at scoping instead of returning a drawing that cannot answer the question.
How the survey is run here
The grid used in Paschim Vihar is chosen for these conditions specifically. Tighter cross-coverage is applied where the material would otherwise imitate a service. Each change of material triggers a fresh calibration, so the depth column can be read end to end. Crews, systems and interpretation are all in-house, with nothing critical sub-let.
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. GIS output as SHP or KML for clients holding a spatial database, plus a PDF set for wider circulation. A signed report setting out coverage, section-by-section depth, no-access areas and the limitations that apply to the drawing. On Paschim Vihar work the report also records the authorities involved — the west corporation zone, DDA on pocket layouts, PWD on Rohtak Road, institutional estate offices — because the deliverable has to satisfy whichever of them receives it. Raw data is retained, so a plotted line can be traced to its measurement years later if a claim arises.
Beyond the basics
What pre-colony features do you find? Irrigation channels, field drains, open wells and abandoned borewells under the levelling fill. A brick-lined well beneath a footing is a structural problem.
Why does fill depth matter? Made ground behaves differently from natural alluvium, changing calibration, bearing conditions and trench stability over short distances.
Do you survey school and institutional grounds? Yes, and they are unusually good ground — open, uncongested and traffic-free, where nothing is visible from the surface.
Is Rohtak Road worked differently? Night-only with traffic management, and quoted separately from the quiet blocks a few hundred metres away.
Do you work at night? Regularly, on arterials and in trading areas where daytime access is impractical. Night working is priced separately because productivity and crew arrangements both differ.
Terms used on this page
Pre-colony feature — irrigation channels, field drains, wells and boundary structures predating the development above them. Fill depth — the thickness of imported material above natural ground, which changes both radar behaviour and bearing conditions. Bearing condition — how well ground supports load, which changes with fill depth and matters to foundation design. Residual risk — what remains unknown after a survey, stated explicitly so a design team can decide how to treat it. SUE — Subsurface Utility Engineering, a framework that grades utility information by how it was obtained rather than treating all lines as equal.
