TORC & DOFF Cleaning

We use the best machines in the industry – the DOFF and the TORC.

We operate from self-contained vans, so a power or water supply is never an issue and are fully trained on and use the best machines in the industry – the DOFF and the TORC. Unlike other steam system/pressure washer systems, these can achieve temperatures of 150°C.

DOFF systems are only available from the manufacturers, Stone Health, and their expertise and systems are the first choice for architects and building maintenance professionals. More information on the DOFF can be found on the Stone Health website: www.stonehealth.com along with videos of the DOFF in action and a list of approved contractors.

Our DOFF system uses steam/super-heated water and will remove:

• Paint coatings
• Certain types of graffiti
• Bird or vermin fouling
• Algae, moss, fungi
• Grease
• Oil
• Chewing Gum
• Other biological matter and will also kill spores
• Wax coatings

There is no need to use a chemical biocide during the removal process or as a protection against further biological matter.

Our TORC system – a very light abrasive system – removes:

• Carbon sulphating
• Lime & cement-based paints
• Paint residues
• Some old oil based paints
• Bitumen
• Lime scale

This does not damage the ‘patina’ of the stone we are working on.
