We were the main specialist exterior cleaning contractor used for cleaning of  St Marys, Tramadog Gwynedd a Coade stone lynch gate.

For this project we used Stonehealths TORC system.

We are now using Restorative techniques “Vortech” which we find a massive improvment on the Stonehealth system

The TORC/Vortech system creates a gentle swirling vortex using a mixture of low air pressure, little water and a safe inert fine granulate.

There are variations in the type of abrasives used depending on the type of substrate being cleaned.

The key characteristics include:
Particle size (maximum size and size distribution)
Shape (rounded, angular etc.)
Hardness (value expressed in Mohs)
