SMUTI

SMUTI is Strength Monitoring Using Thermal Imaging.

SMUTI is a totally new method of monitoring the early strength development of shotcrete. The whole of the shotcrete tunnel lining can be scanned from a safe position in real time using a thermal imaging camera and SMUTI software. 

SMUTI is as quick and easy as taking a photograph. To give an idea of what you see when you look at shotcrete through a thermal imaging camera, a video is posted below. 

SMUTI will only be accurate for the first 24-36 hours. By this time the shotcrete will typically have a strength in excess of 25 MPa.

SMUTI is a 'strength monitoring' method, not a conformity test. If the wrong shotcrete mix is delivered to the pump, the wrong strength will be calculated. Therefore conformity testing is still required to verify that the specification is being met.

SMUTI is implemented in 3 stages:

1. lAB TESTING

First you send small samples of your shotcrete ingredients to Inbye's lab for testing

2. CALIBRATION

Then we need to spray some shotcrete on site so we can calibrate the system

3. TRAINING

The system is ready to use so all we need to do is train your site engineers - this literally takes less than an hour!
