A Primary Mission of the Council is to promote effective means of surface preparation in the maintenance industry using water and water/abrasive blasting techniques.

Operating conditions, cleaning rates, and performance differ substantially from standard equipment with several significant advantages applicable in todays environmentally and safety- conscious society.

Early in 1971, the first ultrahigh-pressure compact intensifier pumps were under development representing the only significant technological change in high pressure pumps in recent history.

Based upon the practical and economical use of prime movers, an operating pressure of 35,000 to 40,000 psi was selected, with maximum pump flow rates to 6 gpm.

Most frequently, this tool is equipped with two to four .009″ diameter nozzles and used to remove heavy, thick materials such as rubber or concrete.

The high speed jets of water cut through many energy-absorbing materials rapidly, and erode large quantities of the more stubborn materials much faster than low pressure/high volume water or grit blasting.

This same tool can be used to do “dental work” on concrete structures removing deteriorated concrete from spaulled areas while simultaneously providing a light surface scarification for new protective coatings.

the same ultrahigh-pressure pump can be used to remove a coating, lightly scarify, decontaminate, or erode deep into the concrete by simply changing the application tool/end effect.

The size of the nozzle used on the rotating lance is dependent upon the thickness and tensile adhesion of the coating.

High velocity jets are especially well suited for this type of use since the jet speed allows actual cutting of the rubber just prior to separation from the substrate.
