Concrete corner crack monitor - Humboldt
- 12 months limited warranty
- Angles between 70° and 180°
- Monitor two dimensional movement
The concrete corner crack monitor uses a hinged mounting bracket to allow monitoring of cracks in corners with angles between 70° and 180°.
Designed for precise crack movement monitoring in concrete corners
The Concrete Corner Crack Monitor is used by structural engineers, building inspectors, and restoration professionals to track the width and movement of cracks that form at corners and junctions in concrete and masonry elements. Objective crack monitoring supports condition assessments and helps identify whether cracks are stable or progressing due to settlement, thermal cycling, or structural loading, as highlighted in industry inspection guides for infrastructure evaluation and maintenance planning.
Professionals value the corner crack monitor for its simple installation, clear measurement scale, and ability to record subtle changes over time during periodic inspections. Compared with visual estimates, this dedicated tool provides repeatable, documented crack width data that improve inspection accuracy and support quality control, risk assessment, and decision‑making in construction, renovation, and structural evaluation workflows.
Inner and outer corner crack observation
Observes both inner and outer corners in concrete and masonry structures. The corner gauges are based on the proven plus gauge design and feature four small alignment pegs that ensure accurate positioning during installation. These pegs are removed once monitoring begins, allowing unobstructed and reliable crack movement readings over time. 
Accurate measurement and flexible installation
The corner crack gauge includes integrated measuring flats, enabling precise measurements with calipers during inspections. It can be securely fixed to the surface using screws or adhesive, depending on site conditions and substrate type (fixings not included).
This crack monitoring solution is commonly used in structural inspections, building condition surveys, infrastructure maintenance, and civil engineering projects. It is valued for its simple installation, repeatable accuracy, and ability to monitor difficult corner geometries where standard crack gauges are not suitable.
Supplied components
Supplied with clear installation instructions and a record sheet to document crack movement readings. Sold in pairs for convenient monitoring of multiple locations or comparative measurements.
Q&A
What types of cracks can this corner crack monitor measure?
