Abstract
A method and strip (10) for sealing between opposed surfaces (22, 24), and formation of a sealable groove (20). The method of sealing utilizes a sealing strip which is introduced between the surfaces, and settable material (26) which is provided between the sealing strip and one of the surfaces (22), wherein the sealing strip (10) is provided with an elongate body portion (12) and a lengthwise extending and laterally extending flexible barrier (14), the sealing strip (10) being introduced through an opening defined by the surfaces such that the barrier resiliently engages the surface (22) and, when the strip is in position, provides a barrier between the body portion and the surface.

A method of sealing between opposed surfaces utilizing a sealing strip which is introduced between the surfaces, and settable material which is provided between the sealing strip and one of the surfaces, wherein the sealing strip is provided with an elongate body portion and a flexible barrier means secured thereto which extends lengthwise of the body portion and extends laterally outwardly from the body portion, the sealing strip being introduced through an opening defined by the surfaces such that the barrier means resiliently engages said one surface and, when the strip is in position, provides a barrier between the body portion and said one surface, wherein the settable material is provided on the strip and supported by the barrier means prior to introduction of the strip between the surfaces.
A method of sealing between opposed surfaces utilizing a sealing strip which is introduced between the surfaces, and settable material which is provided between the sealing strip and one of the surfaces, wherein the sealing strip is provided with an elongate body portion and a flexible barrier means secured thereto which extends lengthwise of the body portion and extends laterally outwardly from the body portion, the sealing strip being introduced through an opening defined by the surfaces such that the barrier means resiliently engages said one surface and, when the strip is in position, provides a barrier between the body portion and said one surface, wherein the strip is introduced between the surfaces using a tool used to form the opening and opposed surfaces, the tool subsequently being removed through the opening.
A method of sealing an upwardly open gap between two spaced surfaces comprising:
- a) providing a sealing strip comprising an elongate body formed of self-expandable material and having first and second opposed side surfaces, said body having barrier means secured to and extending lengthwise of the body and extending outwardly from the body with respect to said first side surface, adjacent to a corner of the cross-section of the body formed by said first side surface and a further surface of the body extending between said side surfaces, said barrier means being formed of resilient material;
- b) introducing said sealing strip into said gap by passing it downwardly thereinto, such that the further surface is lowermost and the side surfaces are generally parallel to the spaced surfaces, and such that the barrier means at a lengthwise extending free edge portion thereof engages one of said spaced surfaces such as to cause the barrier means to resiliently and sealingly press thereagainst, and to position said second side surface of the body against the other said spaced surface and to maintain the first side surface of the body spaced from the other said spaced surface;
- c) introducing settable material into the gap so as to substantially fill the space between the first side surface of the body and said other said spaced surface, leakage of the settable material downwardly past the barrier means being substantially precluded by the sealing engagement of said free edge portion of the barrier means with said other spaced surface;
- d) allowing said settable material to set;
- e) allowing said body to self expand so as to provide an effective seal between the first side surface thereof and a then formed adjacent surface of the set settable material and between the second side surface and the other said spaced surface,
- wherein the settable material is placed on the sealing strip before the sealing strip is introduced into the gap.
A method of sealing an upwardly open gap between two spaced surfaces comprising:
- a) providing a sealing strip comprising an elongate body formed of self-expandable material and having first and second opposite side surfaces, said body having barrier means secured to and extending lengthwise of the body and extending outwardly from the body with respect to each said side surface, adjacent to respective corners of the cross-section of the body formed by said side surfaces and a further surface of the body extending between said side surfaces, said barrier means being formed of resilient material;
- b) introducing said sealing strip into said gap by passing it downwardly thereinto, such that the further surface is lowermost and the side surfaces are generally parallel to the spaced surfaces, and such that the barrier means at lengthwise extending free edge portions at opposite sides of the body engage respective ones of said spaced surfaces such as to cause the barrier means to resiliently and sealingly press thereagainst, and to position the side surfaces of the body spaced from respective opposed ones of said spaced surfaces,;
- c) introducing settable material into the gap so as to substantially fill the spaces between the side surfaces of the body and the respective opposed said spaced surfaces, leakage of the settable material downwardly past the barrier means being substantially precluded by the sealing engagement of said free edge portions of the barrier means with said spaced surfaces;
- d) allowing said settable material to set;
- e) allowing said body to self expand so as to provide an effective seal between the side surfaces thereof and then formed adjacent surfaces of the set settable material,
- wherein the settable material is placed on the sealing strip before the sealing strip is introduced into the gap.
