How to close gap between sliding doors & slab?

Freya

Hi All.  My partner and I are owner building our own home and we have had the exterior walls installed with Hebel Power Panels.  However, we have been left with gaps under our sliding doors which are letting in water to the exterior.  Any ideas about how we can 'close the gap' so we can keep the outside from coming 'inside'?  Thanks

Hello @Freya 

Welcome to the Bunnings Workshop community. It's sensational to have you join us, and thanks for sharing your question about your sliding door gap.

It appears that part of the sliding door frame is not sitting on a solid surface. Can you please lift the plastic moisture barrier and take a photo of the bottom? This will give our members a better idea of what is underneath. Generally speaking, it might be necessary to add more concrete under the aluminium frame. But we will have a better idea once we see what underneath the plastic.

If you have any other questions, please let us know.
