Temperature monitoring service

Don't wait for the crack. Measure the concrete while it develops.

For mass concrete, strength isn't the whole story. We measure core, mid-depth and surface temperatures through the early-age period, so your team can act before thermal limits are reached.

Request a monitoring plan See how it works

Strong concrete can still crack.

A large element can reach its specified strength and still crack early. Heat of hydration builds up in the core while the surface cools faster. The core-to-surface temperature difference (ΔT), held back by reinforcement, foundations and adjoining concrete, turns into tensile stress.

  1. Heat of hydration
  2. Core temperature rises
  3. Core-to-surface ΔT
  4. Expansion, then contraction
  5. Restraint
  6. Thermal tensile stress
  7. Early-age thermal cracking

Elements that need thermal assurance.

  • TG foundations
  • Silo foundations and walls
  • Data-centre foundations
  • Semiconductor fab foundations
  • Heavy equipment foundations
  • Large rafts and pile caps
  • Transfer beams and heavy columns
  • Power and process plant structures

From prediction to proof.

We deliver the full thermal assurance cycle, not just temperature logs.

  1. 1

    Assess

    Identify whether the element carries a real thermal risk.

  2. 2

    Predict

    Estimate heat generation and expected temperature development for your mix and geometry.

  3. 3

    Plan

    Set sensor locations, project-specific control limits and response actions.

  4. 4

    Monitor

    Record core, mid-depth, surface and ambient temperatures live through the critical early-age period.

  5. 5

    Interpret

    Track peak temperature, ΔT, rate of rise and cooling against the plan.

  6. 6

    Act

    Flag when a limit is approached so insulation, curing or cooling can be reviewed in time.

  7. 7

    Verify

    Compare actual behaviour with the project requirements.

  8. 8

    Assure

    Hand over an auditable record that thermal behaviour was measured and managed.

What we measure.

  • Peak internal temperature
  • Core-to-surface ΔT
  • Rate of temperature rise
  • Cooling behaviour
  • Complete temperature history

A typical sensor arrangement.

Three sensors go into the concrete; the fourth port reads ambient air. Sensor positions and depths are adjusted to the geometry of the structure and the project requirements.

Mock-up first

For critical pours, a mock-up block of at least 1 m in its smallest dimension characterises thermal behaviour before the main pour.

Mix calibration

One sensor per cube for general testing; a fixed sensor in two cubes per mix to calibrate strength-maturity.

One temperature record, two answers.

The same temperature history that tracks thermal risk also gives in-place strength through the maturity method, once the mix is calibrated. Thermal assurance and strength decisions from one set of sensors.
