Hydrocleaning, high pressure cleaning or waterblasting is the use of water propelled at high speeds to clean surfaces and materials. By focusing and pressurizing the water stream, the force generated can remove, for example:
- Paint from walls, metal, and highways
- Rubber from runways
- Sealants and membranes from concrete
- Gum from side walks
Any time a hard surface, such as asphalt, concrete or metal, needs to have a coating applied, the surface must first be prepared.
The use of high pressure and ultra high pressure water has been used to prepare various surfaces for the purpose of repair and reapplication of such coatings.
Coatings are used to protect concrete from the elements, rain, salt, and to create a friendlier surface for human use.
Concrete can also be covered with carpet or tiles using a heavy duty glue or mastic.
Asphalt and concrete can be painted to communicate acceptable travel patterns, potential hazards, or for aesthetics.
High pressure water can be used to clean these materials off when new ones are desired.
High pressure water has been used to remove:
Membranes:
- Elastomeric
- Rubber
- Urethane
- Hot applied
Paint from:
- Highways
- Runways
- Parking structures
- Metal surfaces
