Frequently Asked Questions

Q: What surfaces can the L-Shape Acrylic Crack Monitor be used on?

A: This crack monitoring gauge is suitable for a wide range of surfaces including concrete walls, brick and masonry structures, plasterboard partitions, building foundations, and interior or exterior wall corners. It is designed for any flat or L-shaped surface where structural movement needs to be tracked over time.

Q: Does the crack monitor require adhesive or special tools to install?

A: No adhesives are needed. The gauge features improved mounting columns that provide secure, stable fixation at wall corners using mechanical fasteners. The easy-installation system means you can set it up quickly without special tools and remove or reposition it without damaging the surface.

Q: How do I read the crack displacement measurements?

A: The two overlapping transparent acrylic plates each feature clearly printed X and Y axis scale markings. As the crack widens or shifts, the plates move relative to each other. Simply read the offset between the scale lines on each plate to determine the exact horizontal and vertical displacement of the crack in real time.

Q: Is this crack monitor suitable for outdoor use?

A: Yes. The durable acrylic material is designed to withstand varying weather and lighting conditions, maintaining panel clarity and measurement accuracy whether installed indoors or outdoors.
