When cutting steel and reinforced concrete, sharp-edged abrasives are added to the high-pressure water-jet, allowing steel as thick as dozens of centimetres and reinforced concrete that is up to half a metre thick to be cut. Water-jet cutting causes no vibrations to the cutting target, and the amount of material waste remains very small, thanks to its narrow kerf. It also does not result in the release of any hazardous or toxic compounds during the cutting process.

Creosote, i.e. coal tar, is a toxic substance that was commonly used in old buildings, mostly as a water sealant in walls and floors. The PAH compounds that break down in creosote have very harmful health effects. When handling or dismantling creosote-treated materials, it is important to have good ventilation and protective gear. Breathing masks and vacuums should be equipped with active carbon filters. Waste is transported to hazardous waste centres. The work requires special expertise and only experienced companies in the field can carry out creosote demolition.Occupational health and safety officials require the use of various levels of protection, including when handling microbe-damaged materials.
