We specialise in using a low pressure sand jetting system that has been used nationwide for various cleaning tasks. The system, in our trained hands, causes minimal damage to an underlying surface and is flexible enough to tackle most property restoration cleaning tasks. The low pressure sand jet can clean surfaces without injecting large quantities of water into the surface, and with minimal surface damage, at the same time, the 'wet' system also captures dirt and abrasive, preventing the health and safety risks associated with dry blasting.

That being so, there are times when alternative methods are called for, one of which is Dry Ice blasting. Here a surface to be cleaned is blasted with CO2 particles, and the surface is cleaned through thermal shock, and some abrasion of the surface contaminant.

The advantage of this system is that the 'abrasive' evaporates rapidly, so the only 'debris' is the material being removed.

Disadvantages are the costs compared to alternative systems, in particular the raw ingredient dry ice evaporates when it is not used, so needs to be used rapidly.

It is used widely in the printing industry to clean print rollers, and for mould and weld cleaning.

Dry Ice will remove paint from a metal surface, but it is slow, and does not leave a surface keyed suitably for Zinga application

horizontal rule

bulletA very 'clean' cleaning system. Cleaning chemicals / abrasives do not contaminate the work surfaces.
bulletIt is not a chemical process so no noxious or harmful slurries or fumes are generated.
bulletThe system is regularly used indoors, but good ventilation is required
bulletConsiderably less mess than other systems.
