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.
