 UHP water is very effective in cleaning surfaces to remove dirt, debris, oil, grease and jet fuel stains and other foreign material from asphalt and concrete surfaces. As the UHP water passes through the nozzles at high velocity friction heats to water to approximately 140° F. The hot water cleaning is very effective in removing stains from the surface. Gum and other materials deposited on the surface will also be removed.
 UHP water is very effective in removing dirt from cracks in the concrete surface allowing sealers to penetrate the crack and protect the concrete from the damaging effects of salt and chloride penetration.
