Similarly, one or more devices or sub-systems or elements or structures or components proceeded by “comprises . . . a” does not, without more constraints, preclude the existence of other devices or other sub-systems or other elements or other structures or other components or additional devices or additional sub-systems or additional elements or additional structures or additional components. Appearances of the phrase “in an embodiment”, “in another embodiment” and similar language throughout this specification may, but do not necessarily, all refer to the same embodiment.

[0024] In addition to the illustrative aspects, exemplary embodiments, and features described above, further aspects, exemplary embodiments of the present disclosure will become apparent by reference to the drawings and the following detailed description.

[0025] Referring to FIG. 1A, a sealing element 100 is shown, in accordance with one embodiment of the present disclosure. The sealing element 100 comprises a housing 105. The housing 105 may be provided in a shape of square, a rectangle, and so on. The housing 105 may be made of an elastomer, a polymeric material, such as a plastic, a rubber, ethylene vinyl acetate, and a combination thereof. The housing 105 comprises a top end 106, a bottom end 107, a first side 108, and a second side 109. The distance between the top end 106 and the bottom end 107 defines a length of the housing 105. The distance between the first side 108 and the second side 109 defines a width of the housing 105.

[0026] The housing 105 further comprises a plurality of fins 110 provided at outer surface of the housing 105. Specifically, the plurality of fins 110 are provided across the length of the housing 105. In one implementation, the plurality of fins 110 are provided in perpendicular to the first side 108 and the second side 109 of the housing 105. Further, the plurality of fins 110 are provided in symmetrical at the first side 108 and the second side 109 of the housing 105. The plurality of fins 110 may be placed at equal distance from one another.

[0027] Now referring to FIG. 1B, the plurality of fins 110 provided in asymmetrical at the first side 108 and the second side 109 of the housing 105 is shown. As can be seen, the plurality of fins 110 may be placed at varied distance from one another.

[0028] Now referring to FIG. 1C, the plurality of fins 110 provided at an acute angle with respect to the first side 108 and the second side 109 of the housing 105 is shown. In one example, the plurality of fins 110 may be placed at 45 degrees with respect to the first side 108 and the second side 109 of the housing 105. It should be obvious to a person skilled in the art to place the plurality of fins 110 at equal or varied distance from one another and to position the plurality of fins 110 in a symmetrical or asymmetrical manner as explained above.

[0029] Referring to FIG. 1D, the housing 105 compressed is shown. It should be understood that width of the housing 105 becomes less than 5 mm. In one example, the housing 105 is compressed to have a width of 1 mm. In another example, the housing 105 is compressed to have a width of 0.6 mm. FIG. 1D shows the housing 105 (shown in FIG. 1A) compressed which has a width of 1 mm. Similarly, FIG. 1E is provided to show the housing 105 (shown in FIG. 1B) compressed which has a width of 1 mm. Further, FIG. 1F is provided to show the housing 105 (shown in FIG. 1C) compressed which has a width of 1 mm.

[0030] It should be understood that the housing 105 may compressed such that width of the housing 105 prior to compression and after compression can be in the ratio of 10:1. As such, if the width of the housing 105 prior to compression is 6 mm, then the width of the housing 105 after compression can be reduced to 0.6 mm.

[0031] Referring to FIG. 1G, a front view of the sealing element 100 is shown. In one example, the length of the housing 105 is 10 mm. Further, the width of the housing 105 is 6 mm to 8 mm. It should be understood that the width of the housing 105 may be selected in the range of 6 mm to 15 mm or more. Similarly, the length of the housing 105 may be selected in the range of 6 mm to 15 mm or more.

[0032] Now, referring to FIG. 1H, a perspective view of the sealing element 100 is shown. The housing 105 of the sealing element 100 is provided in a solid structure is shown. Further, the housing 105 is provided in the shape of rectangle. It should be understood that the shape of the housing 105 could be square, circular and the like.

[0033] The sealing element 100 can be used to seal a gap provided between concrete pavements. Referring to FIG. 2A, the sealing element 100 used with a concrete pavement 200 is shown. As known, the concrete pavement 200 may be separated by a cut as e.g., a first pavement S1 and a second pavement S2 having a first wall 202 and a second wall 204, respectively. The distance between the first wall 202 and the second wall 204 defines a gap 205 provided between the first pavement S1 and the second pavement S2 to accommodate changes in the concrete pavement 200 due to expansion and contraction. Generally, the gap 205 is provided having a width of 6 to 10 mm or more and liquid sealants or hollow seal are used to cover the gap 205. However, due to at least 8 mm width, the edges of the first pavement S1 and the second pavement S2 may get damaged when vehicles are moving over the concrete pavement 200. In order to overcome the problem specified above and to increase the life of the concrete pavement 200, the gap 205 between the first pavement S1 and the second pavement S2 may be reduced. For instance, the gap 205 between the first pavement S1 and the second pavement S2 may be reduced to 5 mm or less.

[0034] In order to cover the gap 205 of 5 mm or less provided between the first pavement S1 and the second pavement S2, the sealing element 100 is used. As can be seen from FIG. 2A, the housing 105 having a width e.g., 6 mm may be used to insert in the gap 205 provided between the first pavement S1 and the second pavement S2. In one example, the sealing element 100 is inserted using an applicator machine (not shown). Further, the sealing element 100 is inserted into a crack induction cut of the concrete pavements S1, S2. In order to insert the housing 105, at first, the housing 105 is compressed such that the width of the housing 105 becomes less than the width of the gap 205 provided between the first pavement S1 and the second pavement S2. For example, the housing 105 may be compressed to have width of 1-2 mm and brought inside the gap 205 as shown in FIG. 2B. Subsequently, the housing 105 may be released such that the housing 105 expands thereby increasing the width of the housing 105. In order words, the housing 105 expands outwardly and moves closer to the walls (202, 204) of the first pavement S1 and the second pavement S2. The housing 105 expands outward and the sealing element 100 is held against the walls (202, 204) of the first pavement S1 and the second pavement S2.

[0035] As explained above, the housing 105 comprises the plurality of fins 110 provided at outer surface (length) of the housing 105. The plurality of fins 110 are used to provide additional grip to hold the sealing element 100 against the walls (202, 204) of the first pavement S1 and the second pavement S2. It should be understood that the when the housing 105 expands outward, the plurality of fins 110 are also held against the walls (202, 204) of the first pavement S1 and the second pavement S2 and provides additional grip.

[0036] In one implementation, the sealing element 100 comprises an adhesive (not shown) provided at surface of the sealing element 100 i.e., across the length of the housing 105 to hold the sealing element 100 against the walls (202, 204) of the first pavement S1 and the second pavement S2 and to provide additional grip.

[0037] Referring to FIG. 2C, a perspective view of the sealing element 100 placed in the gap 205 provided between the concrete pavements S1, S2 is shown. The gap 205 is provided along the length of the concrete pavements S1, S2, as shown. The concrete pavement 200 is separated by a predefined length of cut, for example, the length of the cut is 15 mm. It should be understood that the length of the cut may be selected in the range of 15 mm to 25 mm or more.

[0038] Referring now to FIGS. 2D, 2E and 2F, the first pavement S1 and the second pavement S2 comprising a cut section 210 is shown, in accordance with one embodiment of the present disclosure. The cut section 210 may be provided in bevel shape, slant, slope or any other shape. The cut section 210 may be a length of 3 mm or less. The cut section 210 is provided to insert the sealant element 100 easily in the gap 205 provided between the first pavement Si and the second pavement S2. Further, the cut section 210 is provided to reduce stress when the vehicle comes in contact with the first pavement S1 and the second pavement S2.

[0039] It should be understood that the above disclosure that the sealant element can be used to seal the gap between the concrete pavements of 5 mm or less. The seal element can be made using a fabrication/extrusion process. The sealant element can be inserted in the gap as a continuous strip with ease. Further, the seal element can withstand high stress due to its expansion property as being in the solid structure.

[0040] While specific language has been used to describe the disclosure, any limitations arising on account of the same are not intended. As would be apparent to a person skilled in the art, various working modifications may be made to the method in order to implement the inventive concept as taught herein.

[0041] The figures and the foregoing description give examples of embodiments. Those skilled in the art will appreciate that one or more of the described elements may well be combined into a single functional element. Alternatively, certain elements may be split into multiple functional elements. Elements from one embodiment may be added to another embodiment. For example, orders of processes described herein may be changed and are not limited to the manner described herein. Moreover, the actions of any flow diagram need not be implemented in the order shown; nor do all of the acts necessarily need to be performed. Also, those acts that are not dependent on other acts may be performed in parallel with the other acts. The scope of embodiments is by no means limited by these specific examples. Numerous variations, whether explicitly given in the specification or not, such as differences in structure, dimension, and use of material, are possible.
