One of the first construction with technology and energy restoration of facades and roofs was been the parent company of the German Museum on Museum Island in Munich/Germany. The solid wall constructions is made of reinforced concrete, stamped concrete and mixed masonry, concrete walls, partially covered with natural stone or concrete walls.

But which system is one of the best to clean all these different substrates gently? This question was also presented for the staff of the architecture firm A + P, who created a public tender for the „concrete repair and - restoration of historic reinforced concrete facades of the „Deutsches Museum". This was the chance for our client, the company Keilberg GmbH & Co. KG from Glauchau/Germany, which competed with his torbo devices on the public tender.

However after receiving the application the architects had to find out more about the torbo system.

Therefore the company Keilberg GmbH & Co. KG was invited to make a pattern area locally and directly on the object. After inspection of the sample surface, they were convinced of the torbo system. Due to these positive results the responsible project manager Mrs. Hille sat with our sales representatives, Mr. Schmatter, in conjunction. After this contact a modified public tender was created that the restoration of the concrete facade was run only with the torbo system.

The foreman of the Keilberg company, who has been on site in Munich, told us that the cleaning of the facade was carried out in two phases. The first phase covered an area of ​​8,000 square meters and was gently cleaned in six months with torbo. The second phase followed and had an area of ​​7,000 square meters. For these areas other methods need more than five years since everything is cleaned gentle.

The Keilberg GmbH & Co. KG has been working since 2002 with our torbo devices and the workers are still amazed what areas of application are covered with our devices. And the architecture firm A + P has already taken more projects with the torbo wet abrasive sandblasting system in the eye so that further calls are pending with torbo.
