GPR concrete scanning in Ahmedabad

Scanforte's registered base is in Ahmedabad, at Rajvi, New India Colony, New Nikol. Surat, Vadodara and Rajkot are covered from this base on scheduled visits, with multiple sites combined into one mobilisation where possible. Structural consultants, forensic engineers, retrofitting and rehabilitation contractors, testing laboratories and asset owners across the Gujarat industrial belt are the primary clients from this base.

• Rebar detection and cover mapping
• PT cable and tendon detection
• Void and delamination mapping
• Core cutting location survey
• HILTI PS 1000 rental with operator

As built reinforcement moves. Ducts sag between supports. Conduits are added during service and never recorded. A drilled hole that severs a main bar becomes a structural repair, and a core through a stressed tendon becomes an incident. Ground penetrating radar answers the question the drawing cannot: what is actually in this element, at what depth, at this exact position, today.

That question comes up in three situations most often: before core cutting, where bars and ducts need to be located and a clear window identified; before drilling and anchoring, on renovation, fit out and strengthening work; and when an anomaly, a void, a delaminated zone or a moisture affected area, needs to be turned from a scattered bright spot into a plan extent that can be marked up, priced and acted on.

Foundations, machine bases, industrial slabs and embedded services, surveyed without interrupting operations, which is the profile of much of the Gujarat industrial belt this base covers.

The HILTI PS 1000 X-Scan is a three antenna ground penetrating radar system that produces plan view images of concrete, not the single line trace of a covermeter or a rebar scanner. It records a 600 by 600 mm image scan grid in a single set up, extendable to 1200 mm by 1200 mm for larger elements, and detects to a stated maximum of 300 mm in concrete. Default settings assume dry, ordinary concrete, so we acquire in expert mode with the phase of the signal preserved and calibrate the dielectric constant on the element in front of us, processed in PROFIS Detection together with our own MATLAB routines.

Enquiry. Send the element type, thickness, exposure condition and what you need to locate on WhatsApp. Photographs, drawings and any previous scan output help us assess it fast.

Plan. We check access, moisture, exposure and reinforcement congestion against your target, confirm radar is the right test, and schedule the visit.

Scan and mark. Calibrated on the element, scanned in an orthogonal grid, and marked directly on the surface for your coring or cutting crew, same visit.

Report, if needed. Depth slices, plan extents and permissible core diameters, issued as a written report when your project requires formal documentation.
