Keeping Bridges Strong: Inside Sixense’s Crossbow Method

How do you assess the health of a prestressed bridge without leaving a mark?

At Sixense, we use the Crossbow method to measure the actual tension inside post-tension cables. This value is one of the most reliable indicators of structure’s remaining service life.

The Crossbow test provides clear and accurate data while keeping every strand intact. It is a fast and non-destructive way to understand how an infrastructure is truly performing.

Over the past three years, our teams have applied this method across Bahrain, Saudi Arabia, and the UAE, helping asset owners extend the life of critical structures and plan maintenance with confidence.

Tip from the field:

Regular tension assessments help detect strand degradation long before visible signs appear. Early insight reduces unplanned maintenance and extends asset lifespan.

Developed by Sixense, Crossbow transforms precise measurement into actionable insight, supporting safer and longer-lasting infrastructure.
