How to stop water seeping through garage wall?

[zhenbin313]

hi, i've found out that water is seeping through my garage wall and I think some maintenance work is required to be done so that it does not cause a big problem down the road.

there are 2 big questions I need help of.

1) Could anyone provide some details on how this dividing fence is installed? Is this hard to be removed for access purposes?

2) what kind of maintenance work is recommended for my garage wall once access is allowed. My mind is hard-plaster the wall to patch gap opening and put on water-repellent paint over it?

I am looking forward to any suggestions.

Thank you.

Welcome to the Bunnings Workshop community @zhenbin313. It's wonderful to have you join us, and many thanks for your question about water penetration.

How much water comes through the wall, is it just becoming damp?

The fence could be removed, but it will require a decent amount of work. Given that your home appears to be newish, I suspect the fence is fibre cement. If this is an old fence that has been left in place, there is a possibility that it is asbestos, as that was a commonly used profile. If the fence was built after 1990, then it wouldn't be asbestos.

The areas you've circled in the image appear not to have had mortar applied correctly rather than a deterioration issue. They can be filled with mortar that's been coloured with an oxide or mortar gap filler.

You could paint the wall, but first, I'd have a professional check to see whether there is a drainage issue on the roof that's allowing water to penetrate the top of the wall. There might be a leak allowing water to enter rather than water penetration from the face of the wall.

Please let me know if you have any questions.

Hello I just saw the photo of your house and I was wondering what your render colour is? I’m looking for a cool beige to render my house

Let me tag @zhenbin313 to make them aware of your query. It appears to be a light sandstone colour finish but let's wait for zhenbin313 to confirm the colour.

If you need further assistance, please let us know.

Hi @zhenbin313,

I will assume you have been living in the house for a while and everything was OK... and then one day you noticed the dampness.

How long ago did you notice the dampness and was it during a wet spell?

With respect to East/West is that side of the house facing North or South?

When water seeps through a wall there is usually a discoloration or staining, which will look noticeably darker than the surrounding areas.

I see none of that which is puzzling 🤔

I would wait for warmer weather and monitor the area.

Cheers
