Hi,
After the rain, we noticed that the tiles and grout were oversaturated in a small area near the garage door. This area is under the veranda cover.
Could someone please advise on the possible sources and pathways of the water?
thanks
Hi @emmab1986,
It’s a little difficult to pinpoint a specific cause based on the photo provided, as it doesn’t give much context around the surrounding structure, edges, or drainage points. If you’re able to share a wider photo of the area, including the surrounding walls, edges, and any drainage points, we’d be happy to take a closer look and provide more specific guidance.
Even under a covered verandah, wind driven rain can sometimes reach areas you wouldn’t expect. If there are large openings near here, it is likely that wind driven rain is a contributing factor.
It could also be that the substrate beneath these tiles was not graded properly and there is a low point beneath these tiles. Considering tiles and grout are not waterproof, wind driven rain could find its way on to the verandah, soak between the tiles and then drain to a low point that is hidden beneath these tiles.
Another thing to check is if any nearby downpipes or gutters are contributing to the water on the verandah. Observing and documenting how they react during the next downpour could help guide you towards issues that may be contributing such as blocked or inadequate gutters and downpipes.
If upon inspection, there is nothing obvious that could be addressed, then it is likely worth speaking with a leak detection specialist who will be able to assist with locating the source of the water. Tools such as thermal imaging cameras can often be used to trace the source of a leak back to its origin.
Let me know if you have any thoughts or further questions. When you can provide some further context, I could certainly assist further.

There is no underground drain near this area, but the balcony drains water towards the north (see photos), while the garage door is to the south.
I’m not sure why this issue is only happening here and not in other areas. Could you help explain the possible cause?
thanks!
Nothing about that corner really jumps out at me.
As I mentioned, it could be that there is a low point in the concrete beneath the tiles that water is draining to. Even if the surface water drains to the north, water can become trapped under the tiles which will pool in low spots in the concrete.
A leak detection specialist could help you determine this through the use of thermal imaging.
Unfortunately, if this is the case, then the only real solution would be to pull up the tiles, regrade the concrete and then relay the tiles.
Let me know if you have any further questions.
