Saugnac Gauges: a story of innovation in crack monitoring

After 15 years in business, Janpierre Saugnac (ETP and ISBA) opened a construction survey practice in 1972 (EUREX, which became EURISK in 1994).

Confronted early on with cracking problems on buildings and structures, he looked for a reliable way to track crack width over time — an alternative to plaster crack monitors, which he considered unreliable. Drawing on the vernier principle, he designed the G1 Gauge, a simple and accurate crack width measurement instrument that is easy to install.

Realising that this solution could also meet the needs of other surveyors and construction professionals, he developed and brought to market the first SAUGNAC gauges for structural monitoring, made in France.

For more than three decades, we have kept our products evolving to meet real-world site requirements: mechanical gauges, digital instruments, wireless systems and a monitoring application…

Our commitment remains the same: to provide simple, reliable tools, made in France, for structural monitoring.
