Prestress Force Measurement Units: Ensuring Reliability in Concrete Structures
Prestress force measurement units play a critical role in ensuring the structural integrity and long-term performance of pre-tensioned and post-tensioned concrete systems. These specialized systems are designed to accurately monitor, measure, and verify the applied and residual forces in tendons and reinforcement cables. Whether for bridges, buildings, parking structures, or precast components, these units help engineers maintain the desired stress levels and detect force losses due to creep, relaxation, or anchorage slippage. Used both in laboratories and in field conditions, they improve safety, reliability, and compliance with engineering specifications.
Civil Structure Test Tech supports B2B clients across North America with a curated portfolio of prestress force measurement solutions for construction, infrastructure, and industrial environments.
Based in Vancouver, BC, we deliver advanced testing systems backed by expert support, quality assurance, and compatibility tailored to real-world needs.

Case Studies
Case Study 1 – U.S. Highway Bridge Retrofit (Illinois)
During a major bridge rehabilitation project in Illinois, prestress force measurement units were installed to evaluate tendon effectiveness in retrofitted girders. The system detected an unexpected force drop in two tendons, allowing engineers to re-stress in compliance with ACI 423 guidelines—saving both time and material costs.
Case Study 2 – Precast Segmental Construction QA (Texas)
In a large precast yard in Texas, embedded anchor force gauges were used across multiple concrete segments for a viaduct project. The data helped validate consistency in tensioning and provided automated reports for DOT compliance.
Case Study 3 – Canadian Hydroelectric Containment Wall Monitoring (British Columbia)
Civil Structure Test Tech deployed a combination of hydraulic sensors and strain gauges in a hydroelectric dam containment wall project. The solution ensured post-tensioned cable systems maintained target forces over long-term loading, with real-time alerts transmitted to engineering teams.
