TORC cleaning and masonry restoration · Bristol

TORC cleaning in Bristol.

The Stonehealth TORC system uses a low pressure vortex of air, water and fine inert granulate to remove paint, graffiti, carbon sulphation and biological soiling from stone, brick and masonry. We specify TORC when a gentle controlled abrasion is needed that DOFF steam alone cannot deliver. Managed by A Star and delivered by our Stonehealth Rosette approved specialist, under A Star RAMS. Delivered across Bristol and South West. Commercial decorating, frame restoration and facade cleaning across Bristol and the wider South West. Cabot Circus and Cribbs Causeway retail through to harbourside offices and the city's stock of painted render and stone. Much of it in conservation areas.

Why Bristol

Why choose us for torc cleaning and masonry restoration in Bristol and South West.

Track record

  • Managed by A Star and delivered by our Stonehealth Rosette approved specialist, under A Star RAMS
  • Inert non silica granulate, damp operated to contain dust and protect the substrate
  • Method chosen to lift heavy soiling while preserving the masonry surface

Right fit when

  • The substrate is stone, brick, terracotta or concrete with heavy paint, graffiti or carbon sulphation that needs controlled low level abrasion.
  • The surface is too sensitive for chemical strippers or grit blasting, but the soiling is too stubborn for steam or soft wash alone.
  • The building is listed, in a conservation area or on a World Heritage site where method approval needs a Stonehealth Rosette approved specialist.
  • A DOFF clean has been ruled out because the soiling is not solely biological or atmospheric, and a survey confirms TORC will lift the layer without substrate damage.

Bristol programme

How we run torc cleaning and masonry restoration schemes locally.

01

Survey

Substrate identified, soiling type and depth assessed, trial patch to confirm TORC suitability, moisture content, previous treatment history, access and containment feasibility.

02

Specification

Granulate grade selected, vortex pressure and water ratio calibrated to the substrate, containment plan with negative air where dust control needs it, damp operation protocol, and the condition record scope.

03

RAMS

Project RAMS covering COSHH for the inert granulate, exclusion zone radius, scaffold encapsulation, dust monitoring during works, noise assessment for neighbours, and traffic and pedestrian management on public highways.

04

Delivery

Encapsulation and MEWP or scaffold setup with full containment. Damp TORC application in controlled passes, continuous substrate inspection to avoid over cleaning, spent granulate and soiling collected by filtered vacuum. On completion, containment removed and a final inspection held with the client or conservation officer.

05

Handover

Post clean report: granulate specification, pass count, before and after photographs, moisture readings, substrate condition record, maintenance guidance and retreatment interval where staining recurs.

Frequently asked · Bristol

What clients in Bristol usually ask first.

Do you handle heritage and conservation-area facades?
Yes. DOFF steam and chemical cleaning are core to the South West programme, including listed buildings and conservation-area shopfronts where pressure washing isn't an option.
How quickly can you survey in Bristol?
Typically same-week. Bristol and the M4 corridor are a regular run for the team from our Dorset base.
Can you work around live retail trading?
Yes. Most Bristol retail work is phased around opening hours, with overnight cuts where the centre requires it.
Is the TORC system safe for listed stone?
Yes. TORC is a Stonehealth conservation system. The low pressure vortex with fine inert granulate is controllable and does not open the stone pores or abrade historic tooling when operated correctly. We run a trial patch at survey and supply method statements for conservation officer approval.
What is the difference between TORC and DOFF?
DOFF uses superheated steam at low pressure to lift biological and atmospheric soiling without abrasion. TORC adds a fine inert granulate into the vortex, giving a gentle controlled abrasion that removes paint, graffiti and hard carbon sulphation. If the soiling is surface dirt or algae, DOFF is ideal. If it is paint or a thick carbon crust, TORC is the right tool. The survey specifies which system suits your substrate.
Will TORC create dust?
TORC can be run damp, which suppresses airborne dust. For large facades or enclosed spaces we add full encapsulation and negative air extraction. The granulate is inert and non toxic, but we treat it as nuisance dust under COSHH and monitor during the work. It is far cleaner than dry grit blasting.
Can TORC remove several layers of paint from brick?
Yes. TORC is effective at peeling paint, bitumen coatings and graffiti off masonry. We adjust the vortex pressure and granulate grade to strip the layers without cutting into the brick face. A trial patch at survey shows the result and the number of passes needed.
How long does TORC cleaning take?
It depends on the soiling type, area and number of passes. A typical residential stone frontage runs 2 to 4 days including containment and handover. Commercial facades run to a programme agreed in writing. You get a day by day schedule after the survey.
