How to block the gap between Colorbond fence and bricks?

[marvinshane]

My property is higher than my neighbor. He complaint of sand coming through the gap. What's the best sealer that I can use?

Hello @marvinshane 

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

I suspect that sand from your pavers is making its way to your fence every time it rains. I suggest using a Saxon 100mm x 10m Black Garden Edge as a border to prevent the sand from getting carried away to the neighbour's side. Carefully insert the garden edging between the pavers and Colorbond receiving channel at the bottom and leave at least 50mm exposed to the surface. This exposed section will serve as a barrier to both the water and sand that is flowing to your fence.

Let me call on our experienced members @Dave-1 and @Nailbag for their recommendations. 

If you need further assistance, please let us know.

Good Evening @marvinshane 

I really like @EricL 's suggestion. I used the same to stop the fine gravel from doing the same for my garden path. You may need to scrape out a bit of a channel in the soil/sand so the edging goes in far enough. One of the main reasons I like it is because it will stop the sand disapearing from your path, that will lead to uneven pavers for sure (if you get them just lift the pavers and add a little sand and tap them back into place with a mallet, not a hammer)

Hi @marvinshane 

@EricL suggestion of Saxon 100mm x 10m Black Garden Edge  is an excellent one. You would just need to use timber stakes to wedge it between the pavers and fence. Alternatively you could use treated pine Plinth which may provide a stronger edge to maintain the pavers in place long term. Its also 50mm higher.

Thank you for all your response, I might do the Saxon Garden Edge, which @EricL  suggested.
Is it okay if I will insert Gap filler rod in between the garden edge and colorbond, then and seal it with Sikaflex sealant?

Hi @marvinshane,

I don't think there'd be much benefit in using a gap filler rod and sealant because the sand will be eroding from below the pavers. If anything, it would make water pool against the fence, which could lead to corrosion issues.

I would just use the garden edge, tap it down below the bottom of the pavers and the fence using a rubber mallet and then lock it in place with some garden edging pegs.

Let me know if you have any further questions.

appreciate your quick response @JacobZ. Might be a stupid question, but Do I insert the garden edges vertically?

[JacobZ]

Hi @marvinshane,

There are no silly questions; they are all relevant. 

Yes, you would insert it vertically.

You would do this by setting the bottom edge in that narrow gap between the fence and the pavers and then tapping it down, so it cuts into the soil below.

Assuming there is space, you could then add the pegs to lock it in place. If there isn't enough room, the edging is likely wedged well enough that you wouldn't need them.

Let me know how you go.

Hi @JacobZ 

Would this Saxon 150mm x 10m Black Garden Edge - 10m   be high enough to use, so I can just insert this Horizontally? or do you think it is not deep enough?

Also, where should I insert the garden peg, between brick and the garden edge, or between garden edge and colorbond?

Forgive me for many questions.

Thanks,
Marvin

Hi @marvinshane,

Unfortunately, it wouldn't be rigid enough to tap it down. For it to be usable, you would have to remove the pavers, dig out the soil, put it in place and then backfill.

If you're concerned about the depth of the edging, you could use a larger piece of rigid edging, such as these Jack 1180mm x 200mm Garden Edging Strips.

Let me know what you think.
