The Challenge: Verification of Filling
In high-density reinforcement, sandwich walls, or “blind pours” (e.g., tunnel form systems, underwater tremie or pipe concrete), visual confirmation of the fill level is impossible. Without digital detection, engineers risk structural voids that are only discovered later through expensive non-destructive testing (NDT).
The Solution: Verifiable Placement in Blind Pours
Digital detection acts as “eyes” inside the formwork. Using acoustic or ultrasonic sensing, the system detects the transition from air to liquid to concrete and signals when the material reaches the sensor position.
Engineering Impact & Key Benefits
- Eliminate Voids and Air Pockets: Ensure complete encapsulation of reinforcement and full filling according to standards (e.g. ACI 309R)
- Underwater Verification: Effectively track levels in bored piles or underwater foundations where traditional measurement is impractical.
- Reduce Test Drilling & Rework: Replace costly core drilling with real-time verification of concrete presence.
- Safe Concreting Against Existing Structures: Monitor concrete placement in challenging geometries to avoid gaps and ensure structural integrity.
- Monitor Concrete Level When Pumping from Below: Real-time level tracking during upward pumping prevents overpressure and incomplete filling.
