Hi,

I had a Tobermore Tegula patio put in about 4-5 years ago. The installer was OK, not perfect. A few biggish gaps on cruves etc.

Anyway, my problem is the moss/weeds etc in the joints. I am having to powerwash it every year now. I brush in the fine sand afterwards but I'm getting tired of it!

Is there any different method I can use to fill in the gaps? A sand/cement type mix that will set?

I know I can never cure the problem but anything that alleviates it would help.

The main open areas are fine, no big gaps, but they tend to get moss. It's the cuts on curves etc that have large ish gaps. I could put my finger down some of them.

Also, I would be worried about putting something in that looked like I was grouting it... i.e a grey filler. I ahve the reddish/gray/beige mix of blocks.

Any advice?

Tegula heather tbh I would replace the bad cuts with new block it's only 5 years old so won't look to different and will weather quickly. I wouldn't normally allow a gap of more than 3mm on my paving so to get a finger into them is not good. Plenty places in dublin will stock you block and just hire a saw or a grinder to do the cuts.

OK I can understand that and while it is another chore (I have a long list) I can get my head around it.

I have a problem in certain areas too with grass growing up, even on narrow, "proper looking" gaps. I don't use chemicals to kill stuff so am battling it.

I was just wondering if there was something I could brush in that would be more effective than the dry sand.

It's like as if I let it get too bad at one point, and even after I power wash it clean, there are still roots deep down and they grow back up after a few weeks.

the only other alternative to relaying is, to apply a good weed killer, pressure wash, wait for it to dry out and apply a good sealer/and stabiliser which will help to stop the weed roots getting hold.

Would it be possible to use a resin mortar? I understand it might not work on the narrow gaps, but there are decent gaps on the curves, and also, over time there has been chipping (mainly from powerwashing) on the corners of the blocks, and resulting bigger gaps.

I could put down a layer of resin and see how much it fills and then a layer of dry sand for the rest.

It's just my back patio and there are no services underneath it so I am not planning on lifting it anytime soon etc. When I laid it I had it made a decent size, so no plans to extend or modify it in any way, in case putting resin in would affect that.
