GPR Survey in Sanand, Gujarat – Underground Cable & Utility Detection

Rates and page checked: 23 October 2026

Why do Sanand projects call for a GPR survey company before digging?

Sanand sits in Ahmedabad district, west of Ahmedabad city, and over the last two decades its GIDC estates have filled with automobile and engineering plants. That growth means new HT feeders, water and effluent lines, fire mains and fibre connections keep going into the same ground, often laid by different contractors who never saw each other's drawings.

When a plant adds a shed, a substation or a new road, the excavation crew is working blind unless someone has looked first. Hiring a GPR survey company in Sanand before the first cut gives the site engineer a map of what is actually there, painted on the ground and written into a report, rather than a guess built on old layouts.

Typical reasons clients ask us to scan:

• laying a new HT or LT cable from a substation to a plant;
• running water, effluent or fire-hydrant pipes across an estate road;
• OFC ducts for factories and the offices that serve them;
• foundations, pits or trenches on an occupied industrial plot.

Which buried services turn up inside Sanand's industrial estates?

Estate roads look orderly from above, yet the ground under their verges tends to be crowded. Plots were allotted and built at different times, so each one brought its own connections. On an industrial route or plot we usually find:

• Power – HT incomers, LT distribution inside the plant, street-light cables and earthing strips.
• Water and fire – supply mains, hydrant rings and sprinkler feeds, many of them in plastic.
• Drainage and effluent – storm drains, sewer lines and process-water or effluent pipes leading to treatment units.
• Telecom – copper cables, HDPE ducts and OFC laid for plant offices and control rooms.
• Process lines – compressed air, gas or other metal pipelines between buildings.

Plastic pipes carry no current, so radar is the main way to pick them up; conductive cables are cross-checked with an EM locator. Our guide to GPR survey in GIDC industrial estates covers estate work across the state in more depth, and power cabling has its own page on underground cable detection.

How is a running plant scanned without stopping production?

Most Sanand jobs happen inside working factories, where trucks, forklifts and shift changes do not pause for a survey team. The work is planned around the plant rather than the other way round:

1. Safety induction and permit. Our crew follows the plant's own work-permit system and PPE rules before entering any area.
2. Zoning. The plot is split into blocks, and each block is scanned when the plant can spare it – a loading bay at night, a yard during a shutdown.
3. Grid scanning. Open areas are covered on a grid so that pipes and cables running in any direction are caught, not only those crossing a single line.
4. EM tracing of live feeders. Where the plant electrical team can give access to a cable at a panel, we connect a transmitter and follow it underground.
5. Marking and handover. Finds are painted out in each zone as it is finished, so civil work can begin there while scanning moves on.

Night or shutdown working is charged separately from the per-metre rate, and we confirm it on the quote before the visit.

How does route work differ between the town, the estates and the highway?

Not every Sanand job is inside a fence. Cable and pipe routes also run through the older town, along the road towards Ahmedabad and out to villages around the estates. Each setting needs a different approach:

• Old town streets are narrow, with house connections, drains and overhead-to-underground risers packed close together, so line spacing is tighter and cross-lines are added at every lane mouth.
• Estate approach roads are wide, but their verges have been dug repeatedly; we scan both shoulders and the median where a crossing is planned.
• Highway and rural feeder routes are long and straight, which suits continuous radar lines with extra passes at culverts, canal crossings and junctions.

Where a crossing will be bored rather than trenched, we scan the bore path and both pit locations so the drilling team knows what lies between them.

What do GPR scanning services in Sanand cost?

Our charge is set per metre surveyed. Standard route or plot scanning is ₹24 a metre; adding a depth profile of detected services as an L-section raises it to ₹32 a metre. Any order under 4 km is billed as 4 km, and because Sanand is outside Delhi NCR, no project here is billed below ₹1,00,000. GST is added on top of every figure.

Large Sanand orders are discounted over their whole length, not just the excess. A Sanand order whose total exceeds 100 km sees each metre fall in price by 25%; exceed 500 km and the fall is 40%; exceed 1,000 km and each metre costs half. Night working, mobilisation, drawings in CAD/GIS and traffic arrangements or permissions appear on separate quote lines. See the slab table in full on our GPR survey price list .

Who distributes power around Sanand, and are we connected to them?

UGVCL – Uttar Gujarat Vij Company Ltd., with its head office in Mehsana – is the state distribution company for north Gujarat. Torrent Power holds the licence for Ahmedabad city itself, so a route that starts in the city and ends in Sanand may pass between two network owners.

Mezux Touch is not affiliated with UGVCL, Torrent Power or any other DISCOM. We work for the contractor, consultant or plant owner who places the order, and our findings go to them.

Does Sanand soil limit how deep the radar can see?

Depth reach depends on what the ground is made of and how wet it is. Clay that holds water, or ground carrying salts, weakens the signal; dry, sandy ground lets it travel further. Around Sanand the picture changes within a single plot – compacted fill under a plant road, natural soil in a green belt, low-lying patches that stay damp after the monsoon.

So we do not promise one depth for the area. A ground penetrating radar survey Sanand engineers can rely on records the depth actually achieved on each section, and says plainly where the radar could not see. If a crossing or foundation depends on proving a deep service, we can open trial pits or drill boreholes at those points on request. Our article on soil conditions and GPR limits explains the physics.

How do our crews reach Sanand from Faridabad?

We have no Sanand office. Crews travel from our Faridabad base with company-owned equipment – 58 GPR systems and 18 HDD rigs in total, run by our own staff, with no hired machines and no sub-letting. Since 2003 those crews have completed 1.5 lakh+ km of GPR survey in 28+ States and UTs.

Sanand is close enough to Ahmedabad and Gandhinagar that routes in all three can share one mobilisation, which lowers the travel cost per kilometre and brings a programme closer to the 100 km slab. The Gujarat GPR survey page lists the other towns we cover in the state.
