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.
