It is forgotten that asbestos is not only found on roofs in the form of eternit (templates) or asbestos-cement roofing (wavelet) but can also be found on flat roofs where asphalt strips – bitumen roofing or cardboard – were used as roofing.

Detection of asbestos in these coverings is only possible on the basis of the results of a pre-remediation survey. The removal of asbestos-containing asphalt strips is quite challenging due to the nature of the material and the time of year in which the work is carried out (asphalt expands and is harder to work with in summer). We, therefore, recommend that this work is carried out at colder times of the year.

The presence of asbestos-containing materials was identified in the various layers of the roofing – asphalt strips – following a pre-implementation survey. Due to the location of the building, which is close to residential properties, a remediation procedure was proposed in a closed controlled zone, which was approved by the investor and the regional sanitary station (hereinafter referred to as KHS).
