When Dubai Airport contacted Waterblasting Technologies it faced a number of challenges. One was finding a waterblasting system that would operate successfully in the 42º-52ºC daylight heat of the summer and also to find the fastest and most productive waterblasting system because of very limited runway closure time. Chemicals, shotblasting and other waterblasting equipment had been tried on the runways, but eventually engineers and management chose the Stripe Hog SH8000T manufactured by Waterblasting Tech
