Asbestos Diagnosis Yverdon

Yverdon-les-Bains: a built heritage affected by asbestos

Yverdon-les-Bains is the second city in the canton of Vaud and the main urban centre of the northern Vaud region. Its history shapes a particularly varied building stock, the result of development strata ranging from Celtic and Roman origins to the industrial and thermal extensions of the twentieth century.

Yverdon’s thermal vocation, linked to the mineral springs exploited since Antiquity, has generated a fabric of hotels and bathing establishments, the most recent buildings of which date from the 1950s–1980s. These facilities were constructed or profoundly renovated with the materials of the time, including acoustic sprayed coatings in large halls, moisture-resistant floor tiles in baths and changing rooms, and high-performance thermal insulation around heating and water treatment installations.

Yverdon’s industrial dimension is equally structuring. The city hosted important industries in the second half of the twentieth century — particularly in the machinery and mechanical engineering sectors — which left a heritage of industrial buildings and warehouses from the 1950s–1980s now undergoing conversion or rehabilitation. Residential districts developed towards Grandson and Cheseaux-sur-Yverdon in the 1960s–1980s complete this picture with a stock of villas and small collective buildings typical of the period.

Which buildings are concerned in Yverdon?

The diversity of Yverdon’s building stock implies distinct risk profiles depending on the sectors.

Residential buildings

Residential districts constructed between 1960 and 1980 around the historic centre — towards Grandson, Cheseaux-sur-Yverdon and the northern sectors of the city — present the classic profile of the period: vinyl-asbestos tiles in apartments, fibre cement sheets on facades and balconies, suspended ceilings in common areas, heating column lagging. These medium-scale rental buildings generate many renovation projects.

Commercial and administrative buildings

Activity zones at Les Jordils and industrial buildings in the craft zone concentrate workshops, warehouses and production premises from the 1950s–1980s. Large corrugated fibre cement roofs, facade cladding, asbestos-cement industrial floor tiles, industrial pipe lagging: these end-of-life or conversion buildings require exhaustive diagnoses before any works.

Thermal and hotel establishments in the spa district, constructed or renovated between 1950 and 1980, present specific configurations: acoustic sprayed coatings in large halls, moisture-resistant tiles in baths and changing rooms, insulation of thermal water treatment installations.

Villas and single-family houses

Peripheral residential sectors from the 1960s–1980s include villas with common materials from the period: fibre cement roofing or annexes, boiler room lagging, tile adhesives, cellar floor tiles.

Common asbestos-containing materials in Yverdon

Yverdon’s diverse building stock implies a wide range of asbestos-containing materials:

• Large corrugated fibre cement sheets on roofs and facade cladding (industrial buildings)
• Asbestos-cement floor tiles in workshops and warehouses
• Lagging on industrial pipes (steam, heating)
• Acoustic sprayed coatings in large thermal halls, gymnasiums and multipurpose halls
• Moisture-resistant floor tiles in baths and changing rooms
• Vinyl-asbestos floor tiles (residential apartments)
• Adhesives for laying vinyl tiles and tiling
• Fibre cement sheets on facades (spandrel panels, balconies)
• Suspended ceilings in common areas of collective buildings
• Lagging on collective heating riser columns

Technical rooms in industrial buildings and thermal establishments — substations, boiler rooms, air treatment rooms — often concentrate the most problematic materials, sometimes heavily degraded after several decades of operation.

Regulations applicable in Yverdon

The canton of Vaud requires the pre-works asbestos diagnosis report (AvT) in any building permit file concerning a building predating 1991. This obligation, reiterated by Yverdon’s municipal services when processing applications, applies to the vast majority of buildings in the city.

Yverdon’s specificity lies in the diversity of building types concerned. Beyond housing, thermal hotels, converted industrial buildings and public facilities from the 1960s–1980s all constitute cases of application. For end-of-life industrial buildings destined for demolition, an exhaustive pre-demolition diagnosis is mandatory — the quantities of asbestos-containing materials these buildings may contain make this diagnosis particularly important for worker protection.

Frequently asked questions about asbestos diagnosis in Yverdon

Old industrial buildings in Yverdon are being converted. What type of diagnosis is required?

For a major conversion (transforming an industrial building into housing or offices), a comprehensive diagnosis covering the entire building is required. This diagnosis must identify all asbestos-containing materials, their location, condition and estimated quantities. It serves as the basis for the decontamination concept and conditions the costing of the project. Without this document, construction companies cannot correctly assess the costs associated with asbestos management.

Yverdon’s thermal establishments carry out renovation works regularly. How should diagnoses be managed over the long term?

For an establishment that carries out regular works, the best approach is to maintain an up-to-date asbestos management file, fed by successive diagnoses. Each phase of works gives rise to a targeted diagnosis on the zones concerned, whose results are integrated into the overall file. This documentary management is recommended by FACH Commission directives for complex buildings.

My commercial building dates from 1978. I want to sell it. Is a diagnosis useful?

A pre-sale diagnosis is not required by law, but it is strongly advisable. It allows potential buyers to be reassured by providing them with an objective assessment, anticipates negotiations on the sale price, and avoids post-sale disputes. For a 1978 commercial building, the probability of asbestos presence is high.

Must tenants be informed before the diagnosis is carried out?

It is advisable to inform occupants of the diagnosis, particularly to reassure them about the nature of the intervention. The diagnostician does not generate any pollution during their sampling, carried out according to strict containment protocols. A simple prior notification specifying the date and objective of the visit is sufficient.

My building was constructed in 1972 with grey ventilation ducts. Are they fibre cement?

Grey ventilation ducts from the 1960s–1980s are very often asbestos-containing fibre cement — it was the standard material for ventilation networks of this period. Sampling and laboratory analysis will confirm this. If asbestos is present, any drilling, cutting or removal work must be carried out with appropriate precautions by a specialist company.

Must the Vaud AvT report mention all materials in the building or only those in the works zones?

The AvT report must cover the zones directly affected by the planned works. It is not mandatory to diagnose the entire building for a building permit — only the parts concerned by the construction site. However, a comprehensive diagnosis is recommended for owners wishing to have a complete picture of the building and to plan their works over the long term.
