HOW IT WORKS

Cleaning operatives work from a Vacuum Cabin, attached to a telescopic arm mounted on a specially adapted truck

An ultra-fine powder is projected under low pressure and removes accumulated pollution deposits without affecting the masonry beneath

Powerful fans at the rear of the cabin capture the spent powder and dust and transfer it to ground level where it is held in containers before being removed for recycling

The boom can reach up to 42 metres (12 floors) from ground level

For high-rise buildings, such as the 56-storey MetLife skyscraper in New York (cleaned in 2001) the cabin is suspended from outriggers secured to the roof

A smaller machine is available for buildings in narrow streets or with other access limitations

The entire process is extremely quick and up to 200m2 can be cleaned in a working day

Traffic management signage put into position

The working site is established and equipment delivered

Pedestrian tunnel erected to ensure thoroughfares remain accessible

All power supplied by Thomann-Hanry - no services required from clients

MARC CROSS, ASSOCIATE DIRECTOR: BUILDING CONSULTANCY - HARTNELL TAYLOR COOK

Despite the presence of exceptionally high levels of pollution which had accumulated on the limestone façade over many years, Thomann-Hanry was able to clean the entire seven storey building in just two days. They organised all the permits and managed the site so that the work could be undertaken on one of London’s busiest streets without disrupting traffic, pedestrians, retailers or office workers. Their operation was excellent and best of all, the building’s appearance was transformed.

ECO-FRIENDLY

façade gommage® is...

The Adelphi, London WC2

Unlike other masonry cleaning systems, façade gommage® offers an extremely eco-friendly cleaning solution. The process does not require water or chemicals and the powders that are used are either biodegradable or have been made from recycled materials. The spent powder and the dirt from the building are eventually recycled for inclusion within Type 1 aggregate.

SECURITY

In organisations or buildings where security is essential, façade gommage® offers the perfect alternative to scaffold.

The cabin, which is manned by a single operative and covers only a small area of your façade at any given time,is removed at night. This ensures that no unauthorised access is possible at any time.

JONATHAN BYRNE, CHIEF OPERATING OFFICER - ROYAL AERONAUTICAL SOCIETY

We chose Thomann-Hanry to clean our building because we needed a system that would transform its appearance quickly, in preparation for our role as ‘Japan House’ hosting Japan’s guests and VIPs during the London Olympics.

The work was completed in a fraction of the time of the alternatives with no disruption to normal business activities during the clean and we were delighted with the results.

In addition to stone cleaning, Thomann-Hanry also offers repair and restoration services.

It is not usually necessary to scaffold a building simply because restoration work is required. Thomann-Hanry has demonstrated that following a clean, virtually all types of work can be undertaken from platforms and without the need for scaffold.

Many buildings in the City and in the West End have benefited from restoration without scaffold. On Fleet Street, Cornhill, King William Street, London Bridge and other locations in the City, dentil repairs, stone indents, repointing, asphalt replacement, painting, lead work, mastic replacement and bird proofing have all been under-taken this way. Similar works have been carried out at many locations in the West End including at the London Marriott Hotel Park Lane where more than 200 windows over seven storeys were refurbished from platforms.

MARK ANDERSON, CHIEF EXECUTIVE & CLUB SECRETARY - LANSDOWNE CLUB

When we decided to clean and refurbish The Lansdowne Club façades it wasessential we could do so quickly and without disrupting our members or any ofthe events we host at the club.

Thomann-Hanry undertook the entire project including surveying the building, obtaining Listed Building Consent and securing road permits. Working from platforms they were able to complete the façade clean and stone repairsexceptionally quickly and without disturbance to members, staff or traffic.

We were very impressed not only with their professionalism but also with the outstanding results and I would not hesitate to recommend their work.

Our associated practice is able to undertake detailed fabric and structural surveys of the façade to produce an annotated photographic report. Additionally, we can provide a specification and schedule of maintenance and repair works for incorporation into maintenance and planning budgets. We also provide an in-house design and inspection service for any structural issues relating to the façade and its ongoing integrity.

façade protection

After treatment

Concrete paving before treatment with Aqua Fend

All-in-one invisible protection against water, oil, dirt, pollution & graffitiOnce building surfaces have been cleaned and restored they should be protected against future weathering and deterioration.

The primary concern is to prevent the build-up of dirt particles and damp which can react with the masonry and reduce its life. Protecting surfaces also extends the cleaning cycle.

Aqua Fend impregnation products offer the highest grade of surface protection. Aqua Fend effectively protects concrete and stone surfaces, forming an impenetrable but breathable barrier against surface contaminants without affecting surface colour.

As the capillaries of the surface are protected, contaminants will literally sit on the surface top, allowing basic cleaning operations to remove the otherwise problematic blemishes. Pollution, oil, grime, grease, bird dropping, algae and other surface contaminants are no longer a problem or expensive to remedy with Aqua Fend treatments.

Aqua Fend offers a quick return on investment in both budget saving and area aesthetics and comes with a 15 year manufacturer’s guarantee.

All-in-one protection against water, oil, dirt, stains and fouling, pollution, graffiti, chewing gum, vegetation, moss & lichens, freeze-thaw cycle, carbonation & ASRResists mild acids, alkalis and fuelInvisible once dry Suitable for walls, floors and roofsNon-film forming – the surface remains fully breathableNon-toxic/hazardousSolvent and silicone free, readily biodegradable0% VOCsUV resistant – does not discolour the treated surfaceInterior and exterior applicationReduces heat loss by keeping the structure dryLimits the formation of efflorescence

AUSTRALIA HOUSELOCATION: ALDWYCH, LONDON WC2CLIENT: AUSTRALIAN OVERSEAS PROPERTY OFFICE SUBSTRATE: PORTLAND STONE

SURFACE AREA: 6,500m²DURATION: 20 DAYSCATEGORY: PUBLIC BUILDINGS

Following Thomann-Hanry’s survey on this Grade II Listed building, the company was appointed by The Australian High Commission (AHC) to undertake a restoration programme, for completion within a tight six-week deadline in time for the Olympics. Works included façade cleaning, stone repairs, restoring high level bronze statues, regilding lettering at the entrance and repainting wrought iron gates. The AHC were not prepared to take any risks with security by scaffolding the 6,500m2 structure and so Thomann-Hanry undertook all these works from platforms.

“Restoration work does not come much more high-profile than this! Land Securities is the largest property company in the UK with a 40 metre high Head Office building on one of London’s busiest streets and retail tenants below, so when Thomann-Hanry approached us saying they could not only clean all the stone, aluminium and glazing from platforms but replace all sealant and defective grout without scaffold as well, we were intrigued. Their systems performed exactly as they said they would and were a perfect fit with our image as an industry leader.” Eamon Condon - Contract Administrator

The campus at the LSE was restored during term-time despite the presence of the large student population through-out the works. Façade cleaning, lead work repairs, stone restoration, repointing and painting were all carried out from platforms. This removed the potential danger and security risks that scaffold would have presented and enabled university studies to continue uninterrupted.

“Thomann-Hanry’s façade gommage® system is the perfect solution for cleaning the exterior of hotels. Their unique system meant we were able to clean three elevations includ-ing the main entrance without disruption to our guests and we were able to keep all our rooms available. The set-up and cleaning process is remarkably quick as they do not use scaffold and most importantly, the results are outstanding.”Andrew Churchill – Chief Engineer
