The BUILDERA CRACKMON® 3D Three-Axis Crack Monitor is a stainless-steel, industrial-grade crack monitor for the repair, restoration, and long-term monitoring of concrete, masonry, plaster, stucco, and steel structures where 3-axis measurements are required. Most crack monitors or crack meters measure in one or two dimensions, but not all three. The BUILDERA CRACKMON® 3D is ideal for foundation and basement restoration, seismic retrofitting, or any structural, geotechnical, or civil engineering project that requires ongoing monitoring of structural defects and cracks in multiple dimensions.
Available in flush, inside, and exterior-corner mount versions, BUILDERA manufactures each CRACKMON® 3D in the USA using state-of-the-art precision laser cutting. Durable type-304 stainless steel with high-contrast laser-etched markings provide permanent readability even in harsh, corrosive outdoor environments.
Fasteners and epoxy supplied separately.
