DIVCON Inc. Spokane Valley, Washington
Using wireless real-time data on concrete maturity, strength, and temperatures, the Divcon team was able to reduce liability and make fast, accurate decisions to ensure the complete safety and integrity of a 40,000 square foot elevated post-tensioned podium slab deck they were building.
PROBLEM
Messy and unreliable wired maturity systems For decades Divcon Inc., a full-service general contractor based in Washington state, relied on wired maturity sensors to monitor concrete strength and maturity in the field. Eventually, they became frustrated with:
mislabeled wires
accidental cutting of wires
accidental damage to sensors
reading errors caused by wire cross-over
Finally, they decided to look for a better, more reliable way to monitor the strength of concrete in the field.

SOLUTION
SmartRock wireless maturity sensors for concrete Divcon adopted SmartRock wireless temperature and strength sensors for a 40,000 square foot elevated post tension podium slab deck.
They tagged 18 sensors and tied them directly to the rebar around the entire perimeter of the slab’s frame. Once connected, the sensors started sending real-time temperature and strength measurements directly to the crew’s smartphones.
RESULTS
Remote monitoring & data sharing Concrete temperature and strength data was recorded in the free SmartRock app (available for iOS and Android), where it could be accessed from anywhere at any time by the site team. This ability to share data instantly was a big time-saver and allowed for fast and informed decision making.
Increased accuracy of results When compared to cylinder break tests, maturity sensors provided much more accurate and consistent results, thereby ensuring the complete safety and integrity of the concrete Divcon was delivering.
Reduced liability & unexpected costs With the automated reports generated by the Smartrock app, Divcon was able to show that the temperature of the ready-mix concrete never dropped.
