Turning data into Understanding.
And understanding into Action.

We think the most powerful engineering breakthroughs start with a simple question:

What if?

What if your refuge chamber was built into the TBM to be readily available at a moment’s notice?

What if wireless gas detectors can be mounted near the cutterhead to continuously stream gas readings for monitoring in real-time?

What if you had options for purchasing or leasing safety and communication equipment on a program designed to work with your specific financial needs?

Strata has asked and answered these questions.

Communication, ventilation, worker safety and emergency readiness are all vital components to underground tunnel construction. Strata is your single source for all.
