Who do we work for ?

Municipalities and Local Authorities

Municipalities regularly undertake infrastructure projects such as roadworks, network modernization, and public construction. These projects significantly impact both residents’ daily lives and local authorities’ schedules. We help local authorities to confidently manage their projects, ensuring smooth execution and minimizing unexpected issues.

Civil Engineering and Public Works Companies

Detect Réseaux empowers civil engineering and public works companies to operate with full confidence by accurately identifying underground utilities before a single machine breaks ground. As a trusted partner on thousands of job sites, we are a vital link in the construction value chain — and a growth opportunity for franchisees ready to play a key role in building the cities of tomorrow.

Project Owners and Managers

At Detect Réseaux, we go beyond locating underground utilities — we deliver the critical intelligence that drives safer, smarter, and more efficient infrastructure projects. Our cutting-edge detection methods give project owners and managers the confidence to plan with precision, reduce uncertainty, and optimize costs from the earliest stages.

Utility Companies

Managing complex underground networks demands precision, reliability, and real-time visibility. Detect Réseaux delivers high-accuracy mapping solutions — including geo-referenced orthophotos and detailed as-built documentation — to help utility providers maintain full control over their infrastructure. For franchise partners, this means contributing to the backbone of modern cities and supporting essential services with cutting-edge geospatial expertise.
