Hi vzgsxr, surface prep is a critical component to waterproofing applications, it is important to always have a smooth surface when applying product. If substrate is prepared correctly there should be no issues with the application of any Gripset's products, we can provide further details, just shoot us a line at info@gripset.com. In addition it is recommended to replace any damaged particle board in wet areas. As for under & over waterproofing, this is a detail that is being pushed by the building industry to offer greater performance and longevity to home owners and continues to be an option home owners and builders lean to for peace of mind. 100% agree doing it right from surface prep to product application, under or over will meet the minimum standard requirement, but its good to know there's plenty of applicators out there offering the additional service as an option. Thanks again for watching and all your support

Hi ExposeClothing, please email info@gripset.com, if you could please send some photos, our technical team will respond to you promptly!

Hi Duck Squash, that method is correct and we would advise to do so! Hope this helps :) Thanks for watching!

Hi Mark, Thanks for watching! The simple answer is no, if you follow Gripsets detail for waterproofing puddle flanges, our options are 1. OP non Porous Primer to SB sealed puddle Flange followed by membrane embedded with RF fabric (the RF reinforces membrane and ensures correct thickness to the down turn edge) 2. BRW PF square adhered directly to flange (no priming required) including downturn followed by coat Gripset liquid membrane(as detailed @ 13:55), again this method guarantees correct even thickness at edge. Membrane thickness to edge is only one of the issues discussed with Flange/Screed set up as shown from 6:00 - 8:00 but its one that can be addressed by the same methods as detailed above, Thanks again, you can find all details on products mentioned above @ www.gripset.com happy waterproofing!

Hi, to respond to this in more detail could you please send through some photos to info@gripset.com - thanks

Hi Nicko, Thread is designed to allow water to drain. Thanks for watching!

Hi Mark, this is the reason we recommend 2 puddle flanges if top membrane fails water will still drain from puddle flange below, flange is designed with leak control feature that should never be sealed, Thanks for watching!

Hi SLim, you will not as this will bond to the PVC and you will be able to cut to expose the waste!

@@GripsetIndustriesPTYLtd Thank you. The Xpress Lay membrane has a criss cross pattern on it and I wanted to smooth it out before glueing down the vinyl flooring. Could I use feathering finish, smoothing or leveling compound on the Xpress Lay membrane?

Hi Simon, insert grate specific drainage Flanges are available, we will cover this topic in detail, in future Sealed for Good Episodes, so make sure your subscribed to be notified, if you need full details now, let us know at info@gripset.com and Thanks for watching

Gripset Industries PTY Ltd. Thanks, looking forward to it. Been subscribed for a while to all your alerts. Keep up making good products and educating people!

Hi Stede, Thanks for watching! it is become common to waterproof under and over, especially upstairs shower areas. we recommend full waterproofing system at both layers including puddle flanges, Thanks

what happens in the event the concrete slab has been presloped and no screed will be used, just tiles onto waterproof membrane@@GripsetIndustriesPTYLtd

@@ExposeClothing With that scenario, as long as there are falls to drain, a single layer is more than adequate! 2 coats! Always refer to the manufacturer's TDS. Hope this helps! :)

@@GripsetIndustriesPTYLtd it sure does, thank you.

Hi Georgie, yes puddle flanges are required on balcony floor wastes. Thanks

@@gripsetindustries1949 Thanks guys! love your work

Hi PDB! if the intention is to only waterproof below screed then any puddle flange will work, twist style is a great design though, Thanks

@@GripsetIndustriesPTYLtd Great Channel. Also been really liking your c1p on my pools. Do I really need to detail the floor to wall connections when it's a one piece poured shell?
