Overview

Post-Tension Monitoring Systems

post-tensioned concrete structures rely on internal force systems to maintain strength, resist cracking, and support high loads. Over time, stress losses from creep, relaxation, or improper installation can compromise structural performance. Post-tension monitoring systems help engineers and asset managers detect changes in tendon force, cable elongation, anchorage movement, and corrosion risks—critical for ensuring long-term safety and extending service life.

This webpage details the latest sensor-integrated monitoring tools designed to deliver actionable insights during construction, stress transfer, or long-term service phases. Load Force Measurement serves clients across North America with scalable post-tension monitoring solutions for bridges, buildings, silos, parking decks, and tanks. Backed by rigorous R&D, expert technical support, and precision-built hardware, we equip B2B clients with dependable solutions for critical infrastructure monitoring, stress verification, and maintenance planning.

Case Study 1: High-Rise Tower Stress Monitoring (Chicago, IL)

During construction of a 40-story residential tower, Load Force Measurement provided embedded strain and jack load monitoring systems. Data captured during each floor’s tensioning process confirmed design force targets and ensured consistent tendon elongation

Case Study 2: Segmental Bridge Long-Term Monitoring (Austin, TX)

Texas transportation officials partnered with us to install long-term post-tension monitoring on a major urban bridge. The system provided 24/7 cloud-based stress data, detecting gradual stress loss near an anchor zone—prompting early intervention

Case Study 3: Parking Structure Rehab Project (British Columbia)

A Canadian engineering firm working on a 1980s parking deck retrofit used Load Force Measurement’s tendon force tracking to evaluate stress loss over time. Our technology identified unexpected variations in cable performance, influencing the repair scope and safety strategy
