How to stop water coming through treated pine sleeper joints?

[Barbara35]

I have had flooding  my neighbours from water through a colourbond fence and flooding my yard.

He will not do anything about this water which floods my yard and randwick council have been of no help after repeated requests to have the neighbour properly drain his property. This has been going on for 20 years.

I have put three rows of treated pine sleepers across the bottom of the colourbond fence and siliconed all of the joints  to divert the water  which is working however the silicone doesn't last and the water comes through the joints.

I desperately need advice on what I can put on these joints between the treated pine sleeper to stop the water.

Hi @Barbara35,

I understand how frustrating ongoing water issues can be, especially when they affect your property for so long. It’s important to remember that water from neighbouring blocks needs to be managed carefully, as restricting runoff can sometimes cause more pressure behind your sleeper wall, potentially leading to damage. Retaining walls are usually designed to allow water to flow through and relieve that pressure.

If you want to reduce water coming through the joints in your treated pine sleepers, using a durable sealant like Sikaflex can be more effective than standard silicone, though water may still find its way underneath. Another practical option is to install drainage in front of the wall to catch and redirect water safely to your stormwater system.

Since modifications affecting water flow and retaining walls can be subject to local regulations, it’s a good idea to follow up with your local council to ensure any changes comply with their requirements. This can help protect your property and make sure the water management solution is sustainable and safe in the long term. 

Please let me know if you have any questions.

Thank you for your reply the sleepers a three high and divert the water to the rear corner where it comes under the colourbond  fence and is diverted with more sleepers down the side to drain.

I will try the product that you have suggested.

I have bought a roll of Jack Edge Barrier protects fences and walls and prevents water however I would have to put this on the front side where the water comes through as the side the water comes from is flush against the colour bond fence and I can not put anything on the side it is coming from.

I will have to wait until everything dries up now.

I really appreciate your help

Kind Regards

I forgot to mention that there is drainage along the fence and all over the yard but the volume that comes through was lessened  with the sleepers and the silicone on joints but sometimes silicon comes out so maybe the Sikaflex will help although it will take quite a few tubes

Hi again @Barbara35,

For larger areas, it's best to go with the large trade sausage version of Sikaflex. It's more economical that way.

Thanks Mitchell,

 There is a 600ml concrete grey Sikaflex 11 f c purform  that is $36.72 and another sika 600ml concrete grey sikaflex pro+polyurethane sealant for $28.65

Could I use the second one it would be cheaper if I could

How do I apply the sausage product?

You could use the Sikaflex Pro @Barbara35. It would still be superior to standard silicone.

For the sausage product, you will need a Paint Partner Aluminium Caulking Gun.

Hi Mitchell,

Could I use hard as nails?

[MitchellMc]

You'd be in the adhesive territory with construction adhesive, like hard as nails, which is not a sealant like Sikaflex, @Barbara35. It doesn't have any waterproofing qualities, though it could work to block the water to some degree.

Thank you Mitchell,

 I will have to wait until everything dries out before attempting this.
