A sheet-like sealing web for use in construction above and under ground comprises a resilient elastic pressure-sensitive adhesive and sealing composition enclosed between two flexible layers, said lower layer not covering the sealing composition in the vicinity of one longitudinal edge of the web and said upper layer not covering the sealing composition in the vicinity of the opposite longitudinal edge of the web, thus forming two exposed sealing strips for bonding the webs to each other in an overlapping position. The novel sealing web can be further modified so that the adhesive and coating composition is not covered by said upper and said lower flexible layer in a narrow area along the longitudinal edges of the web opposite to the sealing strips, thus forming two exposed fixation strips for securing the web to a substrate or for bonding a cover material to the sealing web.

A sheet-like sealing web for use in construction above and under ground comprising a layer of resilient elastic pressure sensitive adhesive and sealing composition having upper and lower surfaces disposed between respective upper and lower flexible layers covering a major portion of the area of said upper and lower surfaces with the longitudinal edges of said upper and lower surfaces being exposed, thereby forming first and second exposed sealing strips at opposite longitudinal edges of said upper and lower surfaces for overlap bonding of said web to adjacent identical webs and first and second fixation strips at the longitudinal edges of said upper and lower surfaces opposite said sealing strips for securing the web to a substrate or for bonding a cover material to the sealing web, said fixation strips being narrower than either of said sealing strips.
