DESCRIPTION OF PREFERRED EMBODIMENTS

(14) FIGS. 1 to 6 show a waterproofing building product, generally indicated with the reference numeral 10, for use in waterproofing a joint 12 between an operative upper first roofing panel 14 and an operative lower second roofing panel 16. In this embodiment the first and second roofing panels 14, 16 are Lysaght Enseam panels. Waterflow along the waterproofing building product 10 is indicated with the reference numeral 17.

(15) Although the below described embodiments refer particularly to roofing panels, it will be appreciated that the invention is not limited to that application and can be employed to provide waterproofing between various other types of building components. The waterproofing building product 10 includes an overlapping section 18 operatively adapted to overlap a portion of the second roofing panel 16. The waterproofing building product 10 further includes an underlapping section 20 operatively adapted to underlap a portion of the first roofing panel 14. The waterproofing building product 10 further includes a transition section 22 located between the overlapping section 18 and the underlying section 20 which connect the overlapping section 18 to the underlying section 20.

(16) The waterproofing building product 10 longitudinally extends between a first end 24 and a second end 26. The overlapping section 18 at the first end 24 includes a ridge overlapping section 28 operatively adapted to overlap a first ridge 30 of the second roofing panel 16, shown in FIG. 5. The ridge overlapping section 30 defines a ridge recess 32 operatively adapted to receive the first ridge 30 of the second roofing panel 16. The overlapping section 18 includes a transverse groove overlapping section 34 operatively adapted to overlap a groove 36 of the second roofing panel 16. As shown the groove overlapping section 34 extends longitudinally between the ridge overlapping section at the first end 24 and the second end 26.

(17) The underlapping section 20 at the first end 24 includes a ridge underlapping section 38 operatively adapted to underlap a first ridge 40 of the first roofing panel 14. The underlapping section 20 includes a transverse groove underlapping section 42 operatively adapted to underlap a groove 44 of the first roofing panel 14. The groove underlapping section 42 extends longitudinally between the ridge underlapping section 38 and the second end 26. The ridge underlapping section 38 defines a ridge insertion portion 46 operatively adapted to be located within a first panel recess 48 defined by the first roofing panel 14. The ridge insertion portion 46 includes a transverse support rib 47.

(18) The overlapping section 18 includes a transverse overlapping flange 50 at the second end 26 of the waterproofing building product 10. The overlapping flange 50 is operatively adapted to be located adjacent a second ridge 52 of the second roofing panel 16.

(19) The underlapping section 18 includes a transverse underlapping flange 54 at the second end 26 of the waterproofing building product 10. The underlapping flange 54 is operatively adapted to be received within a second panel recess 56 defined by the first roofing panel 14.

(20) In the embodiment waterproofing building product 10 the groove overlapping section 34 includes a groove overlapping face 58 having a first groove overlapping width 60 at the first end 24 and a second groove overlapping width 62 at the second end 26. It will be noted that the magnitude of the first groove overlapping width 60 is different, here larger, than the magnitude of the second groove overlapping width 62. The groove underlapping section 38, in turn, includes a groove underlapping face 64 having a first groove underlapping width 66 at the first end 24 and a second groove underlapping width 68 at the second end 26. In this embodiment waterproofing building product 10 the magnitude of the first groove underlapping width 66 is different, here larger, than the magnitude of the second groove underlapping width 68.

(21) The differences in width magnitude enables the building product 10 to accommodate multi-axial changes in direction of roofing panels, that is, changes in angle and rotation as dictated by a particular roofing profile. In this embodiment the first and second Lysaght Enseam panels 14, 16 will exhibit an amount of rotation after fixing. Such rotation is catered for by the embodiment building product 10. Further, to ensure an aesthetically pleasing appearance the waterproofing building product 10 at the overlapping section 18 includes rows of snap-off points 74 to enable a portion of the overlapping section 18 to be snapped off. The underlapping section 20 is not perpendicularly offset relative to the first roofing panel 14. However, as this offset is hidden from view behind the first roofing panel 14, snap-off points are not provided.

(22) The embodiment waterproofing building product 10 is produced by an additive manufacturing method, particularly three-dimensional printing. It is, however, envisaged that the printed waterproofing building product 10 could be used to create a mould for use in an injection moulding process. The embodiment waterproofing building product is printed according to the specific profile of the first and second roofing panels 14, 16 to enable a beneficial watertight seal between those roofing panels as it has a fully lapped joint, an integrated weep hole with additional enhanced silicone application. Three-dimensional printing offers unlimited scope to match existing or future roof profiles. The waterproofing building product 10 can be configured to corrugated iron or a profile sold under the trade mark KLIP-LOCK. Those are likely the most common roof sheet profiles in use in Australia. The waterproofing building product 10 could also be made to more traditional metal cladding profiles and other roofing material.

(23) The embodiment waterproofing building product 10 is produced from Acrylonitrile styrene acrylate (ASA) which provides non-toxic monolithic robustness as well UV and thermal stability. It will of course be appreciated that a range of other polymers could be used for producing the waterproofing building product 10, for example Acrylonitrile Butadiene Styrene (ABS).

(24) In a non-illustrated embodiment a waterproofing building product is provided for use with guttering. In this embodiment the waterproofing building product includes a first underlapping section operatively adapted to underlap a portion of a first roofing panel and a second underlapping section operatively adapted to underlap a portion of a second roofing panel. This embodiment waterproofing building product includes a transition section located between the first underlapping section and the second underlapping section and connecting the first underlapping section with the second underlapping section.

(25) In a non-illustrated embodiment a waterproofing building product is provided for use as ridge capping. In this embodiment the waterproofing building product includes a first overlapping section operatively adapted to overlap a portion of a first roofing panel and a second overlapping section operatively adapted to overlap a portion of a second roofing panel. This embodiment waterproofing building product includes a transition section located between the first overlapping section and the second overlapping section and connects the first overlapping section with the second overlapping section.

(26) It is envisaged that the embodiment waterproofing building product provides alternative aesthetic features. The embodiment waterproofing building product can be painted to match roofing colour. It is also envisaged that the embodiment waterproofing building product is able to be installed without the need for skilled roofing tradespersons.

(27) When using a waterproofing building product to change direction, it is possible to reduce leaf loading on gutters. Reducing the amount of leaves in gutters can deter leakage and also reduce the risk of bushfires. In this application the waterproofing building product is located at the end of a roof edge and the gutter located beneath the waterproofing building product. In one typical installation the gutter is located 600 mm below the embodiment waterproofing building product. Leaves moving down the roofing will tend to reach the waterproofing building product and tend to drift past the gutter below, while water will flow towards the waterproofing building product and cascade into the gutter.

(28) In use, a non-illustrated silicone bead will be located at a position indicated with the reference numeral 70 in FIG. 1. The waterproofing building product 10 includes a non-illustrated integrated weep hole drainage cavity so as to feed water through the waterproofing building product 10 to a weep hole outlet 72. This feature is made possible as a result of the waterproofing building product 10 being produced by way of three-dimensional printing. The integrated hole drainage cavity in effect creates a porous layer in between the an outside and inside surface of the waterproofing building product 10. In this instance, the porosity of the internal infill structure creates a water aquifer so that should the waterproofing building product 10 experience weakness, as is common with any silicone application, then an additional route is provided for water to pass through the waterproofing building product 10. That feature provides enhanced protection against hydro-static pressure (such as prevailing winds and stormy weather), enhanced protection against capillary action (common on metal to metal overlaps), and enhanced protection against silicone application failure.

(29) Embodiment waterproofing building products could be produced with various profiles/shapes to accommodate different roofing profiles. FIGS. 7 to 9, for example, show an embodiment waterproofing building product 80 shaped to be employed with a CUSTOM ORB profile 82. FIGS. 10 to 12 show an embodiment building product 84 shaped to be employed with a KLIP-LOK profile 86. It would be appreciated that embodiment waterproofing building products could be produced to accommodate a range of other non-illustrated building products.

(30) Although the invention has been described with reference to specific examples, it will be appreciated by those skilled in the art that the invention may be embodied in many other forms.
