Preparing a PATIO SUB-Base - GARDEN RENOVATION 

Nice one! 👍🏻

My neighbour mentioned doing this. It was probably the only part of the renovation that really drove me mad! 🤣

Glad im not the only one 😂. Recently just done this, drove me mad trying to level the MOT. Sharp sand compacted on top and it leveled off perfectly with a straight edge within minutes.

@@jonathanb5552 yep thats the one mate, fck trying to level harcore lol.

I agree, I’m thinking the same !!!

Good tip. Thanks

Cheers 👍🏻 I recon you’d be sound doing that, shouldn’t be an issue.

@@NoviceGardener cheers fella. Keep up the grind!

I think it was either 2 tonne or 3 tonne of hardcore. I may have replied to an earlier comment with the exact number. Sorry I can't be of more help!

I used 3 bulk bags if I'm remembering right. About 1 ton each.

​@NoviceGardener what was a price for.a 1.ton bag

You can do it with both. Nothing has come through as of yet thankfully.

The main reason for using geotextile/ landscaping fabric is to separate the sub base material from the subsoil as over time they would mix. It also is used to for filtration and to improve the ground stability. People call it weed membrane as that is what it is primarily sold as in the likes of b&q and wickes etc. But this is more true if you are using to under some decorative stone or mulch on flower beds as when using it 100mm+ underground it is unlikely any grass will grow through anyway due to lack of photosynthesis. Typically I wouldn't recommend using the stuff in 1 meter rolls as it will only help with the separating of the sub-base from the sub-soil and is better in the 1.5 - 2.25m rolls as it'll help improve the ground stability, this can be done with the 1m stuff but it needs pegging to the ground. The difference between the black and white is that the white is non woven and has better filtration properties than the black woven geotextile which isn't suitable for permeable drainage situations.

I’m not 100% sure. But it is quite straightforward once you start. Seems daunting at first, but once you get into the swing of things, it’s not too bad! Good luck with your project 👍🏻

You can't use ballast as it doesn't bind together enough as the particles are too fine and will just wash away.

That’s great, I may try this at some point if I do something similar again 👍🏻

I had 2 bulk bags for my patio and it was about 11 sqm so 4 may do the job for you.

@@NoviceGardener may have missed it but depth were you aiming for on your type 1?

100mm, but that’s just at a minimum

its an interesting concept but Im not sure it would be easier as you would have to make sure its mixed correctly in a mixer and that makes it time consuming. Maybe worth trying on a small area.

You can just mix with a spade and a rake it doesn't need mixing in a mixer

@@yeah-nawould cement be cheaper than purchasing a ton of hardcore MOT
