VJ panel over waterproof membrane

[Sheridan91]

My partner and I are currently renovating our laundry into a combined bathroom and laundry. We are installing hardiegroove panelling ontop of aquacheck wall linings and are unsure on the best method to fix it without compromising the waterproofed membrane that we have used on the joints of the aquacheck. Nailing or screwing on the hardiegroove panelling where we have waterproofed our aquacheck joints would mean puncturing the waterproofing membrane. Would use stud adhesive or something similar be sufficient in these areas?

Hi @Sheridan91,

Thank you for your question about installing Hardie Groove Lining in your bathroom.

Unfortunately, there is no advisable method for installing Hardie Groove that will not penetrate a waterproofing membrane. The Hardie Groove Lining Installation Guide must be followed for it to be a warrantable installation. The method described in this guide will puncture a waterproofing membrane.

Is this in a direct wet area like a shower?

Can you upload a photo of where exactly you are looking to install the Hardie Groove?

It sounds like you've applied a waterproofing membrane over a plasterboard join as an additional measure. Is this correct?

If this is the case, then this membrane may not be necessary, and you'd be fine to screw through it.

If you can upload some photos and provide answers to my above questions, I'm happy to assist further.
