Utility mapping and hidden network tracing
We know where your services run — even if you don't.
When working on an existing building, not knowing where pipes and cables run can cause expensive damage, project delays and — in the worst cases — serious accidents on electrical or gas installations. We map the path of water, heating, drainage, electrical and gas lines with centimetric precision, using professional radio sondes, electromagnetic locators and — for non-metallic networks — dual-antenna ground-penetrating radar. We deliver an immediately usable operational plan, with floor markings (tracer paint on request) and CAD/DWG files overlaid on the architectural plan for designers.
Mapping techniques
For pressurised piping we use radio sondes inserted into the line through an access point (tap, valve, manhole) and tracked at surface level with a handheld receiver. For non-pressurised conduits (sewers) we use CCTV with integrated sondes that return position and depth every metre. For buried electrical cables we use passive electromagnetic induction (for live cables) or active (with signal generator). For non-metallic conduits and PVC ducting we use 250-500 MHz ground-penetrating radar, capable of detecting objects up to 2-3 metres deep. Technique selection depends on network material and ground conditions.
Final deliverables
We deliver a plan with documented network paths, measured depth at survey points (typically every metre or at every direction change), on-site markings with temporary or permanent tracer paint (on request), and — on large sites or for designers — CAD/DWG files directly overlaid on the architectural plan. We include a colour-coded legend by system type (water, electrical, gas, drainage) per the UNI-CIG standard. All documentation is immediately usable by designers, construction companies, safety officers and surveyors.
When mapping is needed
Before excavation work or wall chasing to prevent breaking pipes and cables, especially in buildings with incomplete or missing technical documentation. On industrial acquisitions and change-of-use to document as-is system conditions. During design of major renovations, to avoid overlaps with existing systems. As part of the safety coordination plan documentation for sites of a certain size.
Where we operate
Our operative base is in Casale Monferrato (AL). We operate throughout northern Italy — Piedmont (Turin, Alessandria, Asti, Cuneo, Vercelli, Novara), Lombardy (Milan, Bergamo, Brescia), Aosta Valley, Veneto (Venice, Verona, Padua), Liguria (Genoa, Savona, La Spezia), Emilia-Romagna (Bologna, Modena, Parma) — and on request also in France and Switzerland with agreed response times. Our logistics keep a single dedicated technical crew on site from initial survey to intervention completion, avoiding handovers between teams and ensuring continuity throughout the job.

Frequently asked questions
Does it work on complex industrial sites?
Yes — we have years of experience on multi-network industrial plants: water, fire protection, technical gases, process drainage, compressed air networks, data cable ducts. On large plants we work with dedicated crews over multiple days.
Is mapping destructive?
No, it is completely non-destructive. We do not excavate or open chases — the technique is based on electromagnetic and ground-penetrating radar from outside. Any small openings needed to insert sondes at access points are agreed in advance with the client.
How long does a full mapping take?
Half a day for a standard home. From 1 to 3 days for an industrial warehouse or large condominium, depending on size and network complexity.
