Different types of materials are possible to use for waterproofing of green roofs. One of these materials is bitumen sheet. Two types of bitumen sheets are used for surface treatment when applied in the roof vegetative structure. In the part where the bitumen sheets are under the vegetation layer, a fine grain gritting is used. In the part of the roof, where the bitumen sheet extends to the surface (above the level) of the vegetation stratum and is exposed to UV radiation, the coarse grain gritting is used. Water in the liquid and gaseous form between the layers of bitumen sheets may be a source of the failure and subsequent damage of the entire roof. Particular emphasis should be placed on the design of bitumen sheets, which are set in one layer [1]. The content of water in bitumen sheets is determined by two test procedures. Although only one procedure is currently valid, it is possible to meet both test procedures in the practice. It is therefore advantageous to know the relationship for a quick orientation to determine values of the water-absorbing capacity of the given bitumen sheet.
The article deals with the issue of the water absorption of bitumen insulating sheets in terms of sprinkling. It compares two methodologies that can be used to determine the absorbency of bitumen waterproofing sheets in terms of test procedures. Based on the experimental measurement, it compares the water absorption results of both methodologies for separate bitumen sheets and determines the interdependence between individual results and investigates the effect of selected parameters on the water absorption of bitumen sheets. Results were formulated based on the statistical evaluation of data obtained from laboratory measurements. |
