YieldPoint Inc.

We are a dynamic, global company in Kingston on the shore of Lake Ontario, in Canada. Our core skills are in the design and manufacturing of monitoring solutions for the measurement of all aspects of rock mass and reinforcement behavior around underground excavations.

Our highly innovative product line comprises both digital and optical instrumentation, which we support with world-class geotechnical research expertise. Case-in-Point, in 2019 we have introduced a new Bluetooth 5 geotechnical product line.

New!! Bluetooth 5 Product Line

YieldPoint’s BluPoint technology integrates Bluetooth 5 into geotechnical instrumentation. Bluetooth 5 features the same low power features as BLE but with 4x range (50m). YieldPoint’s BluPoint App provides Android Smartphone and Tablet functionality. Advantages of BluPoint instruments include:

• Extended range up to 50m (4 x BLE)

• Android phone/tablet access

• Extremely low energy

• User friendly BluLoggers

• BluGateways enabling WiFi, LTE-M connectivity

• Cloud data platform (VantagePoint) and analytics (+VantagePoint)

• Economical pricing

Typical applications include:

Ground movement monitoring

• Extensometers for precision monitoring of hard rock
• Civil extos for monitoring subsidence in soft rock
• GMMs for measuring convergence in potash and salt mine
• Crackmeters for monitoring individual cracks and interfaces
• Tiltmeters for monitoring angular deformation of structures
• Crown Pillar Monitoring

Reinforcement monitoring

• Optically instrumented rebar bolts with 1.25mm spatial resolution
• Digitally instrumented rebar bolts
• Instrumented 7-wire stand cable
• The world’s only instrumented Split-set bolt
• Instrumented fore-poles for large civil tunneling projects
• Tieback monitoring downtown Toronto.

Geo-environmental monitoring

• Thermo-strings for mining in frozen ground
• VW sensors and interfaces for monitoring stress and pressure
• VW interfaces for water-level monitoring
• HID cells for stress change monitoring
• Temperature monitoring for deep mining
• High resolution (1.25mm) optical thermal monitoring
