1. Installation of nets with double Polyane (instead of a simple one) by discussing with the principal to meet his specifications for the operation and his requirements.

Advantage of the double Polyane: the first soiled skin closest to the roof is removed by the asbestos remover and still remains a second protective skin in order to wait for the air analysis results.
Implementation of double Polyane:
The polyane used must be 200 µm thick to comply with regulations.
We ensure watertightness by using tape, clamping vices (or crampons), battens with light doweling, etc.

2.  Laying a heat-shrinkable or heat-welded film as close as possible to the roof before laying the netting allows perfect sealing, a real alternative to polyane film(s) on active sites or on storage areas.

This solution is particularly recommended in a sensitive environment such as a factory with a production line or with personnel working under the work area. This solution also makes it possible not to immediately cover the asbestos-free roof, because the thermo resists bad weather (rain and small storms).

Laying of netting + heat-shrinkable , insulating material that shrinks under the action of heat, it does not allow air or liquids to pass for safe confinement. Traditionally used for boat winter protection, the heat-shrinkable net comes in the form of an opaque white or gray tarpaulin which makes it possible to perfectly seal asbestos removal sites for the containment stage.

The advantage of our solutions is to be “turnkey”, from the study after on-site visit to the realization in autonomy and finally the supply of a PV (Process-Verbal) of reception. We can be present from the start of the project to exchange with the authorities in order to study the best possible solution according to the requirements of each one.

Depending on your needs in terms of surface area, volume to be treated and the configuration of the premises, CATMORA GROUP © analyzes the solution to your work problems for an optimal, secure and fast implementation.
