There was a need to insulate a concrete tunnel at the water treatment plant in Brussels. The objective was to prevent the heating up and expansion of concrete walls (0.30m thickness) after cracks were injected with epoxy mortars against water leakage.

Max temperature allowed: 167°F (75°C)
Temperature hot air inside when in operation: 248°F (120°C)
Air Pressure: 1.2 bar
Air speed in tunnel: 10m/sec
