Abstract
Abstract The method involves the laying along each groove or space, a longitudinal sealing element having an inverted flexible channel which bridges the groove or space and having lateral flange parts extending over adjacent portions of the concrete structure. A junction sealing element is disposed at each interconnection of the grooves or spaces, the junction sealing elements also having, like the longitudinal sealing elements, inverted flexible channels and lateral flanges, the channels of the junction sealing elements being in ''''L,'''' ''''T'''' and ''''X'''' form for the sealing of the intersections of said grooves or spaces.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
183 words
A method of sealing interconnected grooves, gaps or other spaces between sections of a concrete structure, the method including the steps of arranging along each space a flexible longitudinal sealing element having a longitudinal inverted flexible channel part open along its lower side and having also integral flexible flanges extending laterally outwardly from the lower open side of said channel part, said flange at one side at least of said longitudinal sealing element being disposed substantially flat upon the concrete structure, arranging at each interconnection of adjoining spaces, a junction sealing element having angularly related flexible channel parts and associated integral flexible flanges corresponding to the flexible channel part and flexible flanges of said longitudinal sealing element, the flexible channel parts of said longitudinal and said junction sealing elements extending over corresponding parts of the spaces and the flanges of said elements extending over adjacent portions of said concrete structure, connecting the channel parts of said sealing elements together to provide a generally continuous seal, and applying screed to the concrete structure so as to cover the flange parts of the sealing elements.
Claim 2
Independent Claim
183 words
A method of sealing interconnected grooves, gaps or other spaces between sections of a concrete structure, the method including the steps of arranging along each space a flexible longitudinal sealing element having a longitudinal inverted flexible channel part open along its lower side and having also integral flexible flanges extending laterally outwardly from the lower open side of said channel part, said flange at one side at least of said longitudinal sealing element being disposed substantially flat upon the concrete structure, arranging at each interconnection of adjoining spaces, a junction sealing element having angularly related flexible channel parts and associated integral flexible flanges corresponding to the flexible channel part and flexible flanges of said longitudinal sealing element, the flexible channel parts of said longitudinal and said junction sealing elements extending over corresponding parts of the spaces and the flanges of said elements extending over adjacent portions of said concrete structure, connecting the channel parts of said sealing elements together to provide a generally continuous seal, and applying screed to the concrete structure so as to cover the flange parts of the sealing elements.
Claim 3
Dependent Claim
48 words
A method as claimed in claim 1, wherein a longitudinal sealing element is connected to a junction sealing element by engaging in one end portion of the channel part of said longitudinal sealing element, a joining element which protrudes from a channel part of said junction sealing element.
Claim 4
Dependent Claim
43 words
A method as claimed in claim 1, wherein the screed is so applied to a section of the concrete structure that the screed has an exposed surface which is substantially level with the top of the channel part of each adjacent sealing element.
Claim 5
Dependent Claim
57 words
A method as claimed in claim 1, wherein the screed is so applied that the depth thereof is less than the depth of the channel parts of the sealing elements, and wherein floor covering material is applied to the exposed surface of the screed so as to be substantially flush with the tops of said channel parts.
Claim 6
Dependent Claim
60 words
A method as claimed in claim 1, wherein said sealing elements are assembled on the concrete structure, in the form of an endless gasket system, the hollow interior of the channel part of the longitudinal sealing element communicating with the hollow interior of the associated channel part of the junction sealing element to which said longitudinal sealing element is connected.
