Product DescriptionThe Buildera CRACKMON® 4020A Crack Monitor is a heavy-duty, commercial-grade crack monitor for the repair, restoration, and long-term monitoring of concrete, masonry, plaster, and stucco structures. Engineered and made in the USA from premium extruded polymer, the new CRACKMON 4020A offers unique features for civil/structural and geotechnical engineers.

X-Y Measurements Plus Polar Magnitude with TickDots™

The X-Y measurement grid includes a new polar-magnitude measurement function that computes the angular hypotenuse (magnitude) of displacement from the zero-crossing. To improve reading accuracy over the entire range, the measurement grid sports variable-length tick marks as well as patent-pending TickDots at 1x1-mm intervals. TickDots improve crack-measurement accuracy as the measurement cross-hairs traverse the grid. This is particularly helpful when the two plates are no longer parallel.

Vibrant, High-Contrast Measurement Grid

We print the CRACKMON 4020A in five process colors, including a high-contrast rich-black text UV-cured over a thick double layer of brilliant opaque white ink. The result is a bright, bold measurement grid with a 2X contrast improvement that is much easier to read over a wide range of lighting.

Engineering Traceability to the Crack

To improve engineering traceability, each CRACKMON 4020A crack monitor features a unique 15-character serial number that tracks the country of origin, design revision, and unique ID. This ensures forensic traceability in the field and offers a significant benefit in report writing and litigation.

Tamper-Resistant Mounting Flexibility

Mounting methods include epoxy and/or fasteners. Horizontal and vertical slots are optimally sized to accept four different screw sizes, including US (#8/#6) and metric (M4/M3.5) fasteners. A stainless-steel Torx-Plus® tamper-resistant mounting kit with anchors is also available. To ensure a secure and trouble-free installation, Buildera also offers corrosion-resistant stainless-steel washers to help distribute the load.

Peel-and-Stick Drilling Template

When hammer-drilling hard or rough surfaces like concrete or stucco, the percussive impact from a hammer drill makes it tough to accurately drill holes in the right place. A new impact-absorbing drilling guide (patent pending) features an aggressive adhesive that sticks to concrete, masonry, stucco, steel, wood, and other rough surfaces. Simply peel it, stick it, and drill it. Experience perfect holes every time—saving time and money.

Value for Money

The CRACKMON 4020A offers more value than any crack monitor on the market today. When purchased in bulk, prices are competitive with traditional crack monitors, but with the benefits and premium features that only the CRACKMON 4020A delivers.
