Before any work of demolition or removal of asbestos, the company must send the work plan to the supervisory body at least 30 days before the beginning of the work. In case of urgency, there is no thirty-day obligation, but the date and time of commencement of work must be communicated. In terms of costs for remediation by removal, we have seen that the cost for asbestos disposal and removal starts from $ 20 per sqm. For the asbestos removal Vancouver this is the best option now.
Asbestos encapsulation and slabs
Compared to removal, encapsulation is certainly a cheaper remediation activity. The asbestos encapsulation procedure involves treating the material and the slabs with products that cover the material. In this case, the artifact is not removed but protected and secured.
The intervention must be done in compliance with Ministerial Decree. The asbestos remediation procedure through encapsulation secures the material making sure that the asbestos fibers are fixed to the material and their dispersion is not possible.
In order to guarantee that the intervention is done correctly, a certificate of conformity of the works must be issued. Furthermore, a maintenance and control program must be provided to verify the validity of the intervention over time.
Asbestos confinement or over-coverage
This remediation technique involves installing a new roof on the existing roof asbestos confinement. This intervention is possible only if the underlying structure in asbestos cement is able to support the weight of the new covering. Over-coverage is now a little-used asbestos remediation technique and as we have seen very expensive.
The legislation on asbestos remediation
With regard to the legislation on asbestos remediation in our country, we highlight the fundamental standards, which over the years have been joined by high standards, laws, and regional circulars.
When asbestos is dangerous
Asbestos is a mineral with a fibrous structure. Its fibers are resistant and extremely thin. To give you an idea, a fiber is about 1400 times thinner than a hair.
Asbestos is resistant to fire, to acids, to traction, it is practically indestructible. Being a fibrous material, it is extremely flexible and has high thermal and acoustic insulation qualities. All these features have led to the use of asbestos in construction, and not only, since the early 1900s until the end of the 1980s. It is estimated that over 3,000 different products containing asbestos were created.
Unfortunately only after many years it has been discovered that asbestos is extremely dangerous for health and breathing its fibers is highly carcinogenic with the risk of various types of cancer, the best known is mesothelioma.
The legislation subdivides the materials into friable and compact and indicates if and how to proceed with asbestos removal:
Friable asbestos: that is that they can crumble with manual pressure very dangerous. Friable asbestos is dangerous and needs to be cleaned up. Compact asbestos crumbles only with the use of mechanical tools. In this case, there are no particular health risks.
Asbestos in construction: where it was used
In construction, its use has peaked for about 20 years since 1965 for its most famous product, asbestos-cement, which we can find:
- Covers of asbestos cement: asbestos roof and corrugated roofs , tiles, slabs
- Insulation of false ceilings, attics, heating pipes: in the form of wool or felt with asbestos.
- Water chests or tanks: materials with thick asbestos cement.
Seeing how many artifacts there were, you can understand how important it is to carry out checks at home or in the condominium and eventually proceed with asbestos removal.
