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

SmartRock2 wireless maturity sensors for concrete

Divcon adopted SmartRock2 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 SmartRock2 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 Smartrock2 app, Divcon was able to show that the temperature of the ready-mix concrete never dropped.

Poured concrete curing at jobsite

SmartRock2 offers a much more accurate version of the strength measurement in the concrete.

When I was 400+ miles away from the jobsite and not able to be there all the time, I was able to get the Foreman and Superintendent to adopt the technology and share with me remotely for real-time information sharing and decision making.
