Sewage Pipes | Asbestos-Cement Products

The manufacture and usage of asbestos-cement in Germany was band by the amendment of the Hazardous Substances Ordinance (Gefahrstoffverordnung) in 1993. The company Eternit changed its manufacturing process to non-asbestos containing fibre cement between 1987 and 1993. Non-asbestos containing fibre cement consists of approx. 40 % Portland cement (binder), 11 % additives e.g. limestone, 2 % synthetic organise reinforcement fibres (vinyl alcohol-fibre or Polyacrylnitril-fibre) and 5 % cellulose fibre. Asbestos-cement installed prior to 1993 may remain installed provided it is still in good condition. Asbestos-cement is classed as non-friable. Particle emission is therefore only likely when it is damaged or in weathered condition.

Asbestos-cement cladding

Exterior cladding of corrugated asbestos-cement sheeting. In this case several elements have already been exchanged.

Asbestos-cement cladding

Damaged asbestos-cement cladding on the roof of a high-rise building. Replacement is recommended to prevent the emission of asbestos particles at damaged edges.

Asbestos-cement cladding

Damaged asbestos-cement wall cladding. Enhanced emission is expected due to the numerous broken edges. The man-made mineral fibre insulation is also exposed causing additional emission of particles (see Section MMMF).

Sealing compound

Sealing compound between two exposed aggregate concrete slabs. Owing to the date of construction and its appearance the compound it  is thought to contain asbestos. This type of asbestos containing compound known as Morinol was predominantly applied in the former German Democratic Republic.

Roofs | Parapet Walls and Dormers | Asbestos-Cement Products

Corrugated asbestos-cement roofing.

The asbestos is embedded within a hard cement matrix. Provided the asbestos-cement sheeting remains in good condition and is not damaged asbestos particles are not readily released to the environment.  The total asbestos content lies below 15%.

Flooring and Wall Tiles | Asbestos Containing Vinyl Products

Floor Flex tiles

Floor Flex tiles made of asbestos containing PVC. The tiles have a relatively small format and have a typical pattern. These tiles were available almost in any colour.

Floor Flex tiles

Floor Flex tiles

Floor-Flex tiles were made of hard PVC and contained approx.  5-20 % Chrysotile. The asbestos fibres are embedded within the plastic and are not easily emitted. Typically the tiles were 25cm x 25cm or 30cm x 30cm and were quite brittle.

Floor Flex tile adhesive

Black Floor Flex tiles and black tile adhesive. The tile adhesive  also often contained asbestos and sometimes PAH.

Floor Flex tiles

Floor Flex tiles may be frequently found underneath other flooring.

Window Sills

Asbestos containing window sill

Typical asbestos containing window sill often found in buildings constructed during the 1960's or 1970's. The material is non-friable, so that significant emission of asbestos is unlikely. The application of machine hand tools during removal should be avoided owing to enhanced particle emission. Health and safety measures are described in "TRGS 519".

Lift Brake Pads


Lift brake pads

Cable lift drives were fitted until 1989 with asbestos containing brake pads. Asbestos content was as much 40%. This picture shows a decommissioned lift drive. As people seldom access the machine room and brake pads are classed as non-friable, potential risk to the building occupants is considered to be small.

German regulations i.e. "TRGS 519 (Section 16.4)" and "BGI 664" describe health and safety measures for maintenance and repair of brakes and clutches.
