For elastic sealing of construction joints or cracks with sealants in the shape of thin-layered tapes of elastic bitumen material which is protected by aluminium foil. 


 

The elastic sealing of construction joints and cracks is the aim of everyone in the industry of building materials. It is crucial and it cannot always be achieved by silicone, polyurethane or other types of sealants applied by extruding. In many cases, it is necessary that the sealant covers very wide areas around the joints which allow the overlapping with the following covers or the draining of the water away from the joint. This could be easily accomplished sealants in the shape of thin-layered tapes of elastic bitumen material which is protected by aluminium foil.
