- Is 1:50 (2%) too much fall for a patio?
It is noticeable…Posted 2 years ago
According to paving expert typical fall for residential paving is 1:60 so you’re not a million miles away from that. I would only alter it if every time I looked at it I thought “that don’t look right” in which case it’d be worth it just to quieten that internal voice.

Sounds fine to me. Doubt you can see it unless its against a fence (and then I’d suspect the fence is out of level)Posted 2 years ago
Just so you can gauge it against something.
Road camber is generally 1:40 (2.5%) supermarkets usually want max 1:60 in their car parks so people can easily push trolleys.Posted 2 years ago
Ive set out a combined bin store and bike store today at that grade. I don’t expect Dan Atherton to use it as a section of his next red bull hardline course.Posted 2 years ago
It also depends how it falls in relation to it’ surroundings. Is it all falling away from the house at that grade. Can you get perpendicular and a distance away from it to notice the fall or does it go full width etc etcPosted 2 years ago
I’d say 1:50 is pretty steep, given 1:200 is the minimum gradient for road drainage.Posted 2 years ago
Once your beloved has decomposed a bit I’m sure it will flatten outPosted 2 years ago
Sounds well steep to me, unless you have very specific reasons that you can’t put in a retainer and backfill with crusher to make it level (obviously that means more groundworks and expense). At least you’re not going to get puddles!Posted 2 years ago
“It is noticeable…”
Yes, I’ve had this. My paving wasn’t close to a building and a small area, I set it almost level and it drained well. If 1:200 is good enough for a road…Posted 2 years ago
1:200 is not good for a road.
Most roads are designed to be no slacker than 1:100 longitudinally most councils will want see 1:80 if achievable.Posted 2 years ago
1:50 will be fine. It’s the default back fall for a railway station platform, do you notice that when you catch the train in the morning?
Any less such as >1:100 is likely to result in ponding.Posted 2 years ago

i can assure you the Morrison’s in Yeadon isn’t 1:60. Felt more like 1:5 when I was a schoolkid working there!!!

1:60 is the maximum gradient in car parks etc for wheelchair accessibility. They’d try and achieve that all over the car park if possible.Posted 2 years ago
Roads – it’s the camber that provides the drainage, not just the longitudinal gradient.
As said above, footpaths are (supposed to be) 1:60, so walk down the street and see if that’s noticeable to you.Posted 2 years ago
Well its a patio so think tables and chairs…Posted 2 years ago
Anyway, luckily its only marked out and graded so we are going to fix this. Meanwhile we are having a discussion about joint gaps, landscaper wants 15mm, I want 5mm. Its sawn and honed indian sandstone, 600×900.
He says smaller than 15mm and the sand cement joint, he suggested, will not stay in. I want smaller gaps because I have the same flooring for my garden room and kitchen and I want ti to be tight and neat.
Can sand cement stay in 5mm gap, or should they joint it with another product?Posted 2 years ago
Firstly before pointing let’s get it laid right. Indian sandstone has a nasty habit of popping and rocking if not done properly. Full bed and a SBR/cement primer painted on the back of each slab prior to laying 😉Posted 2 years ago
Thats exactly the plan, There is a concrete base, its been graded with 20mm to dust to get the level. Then gonna use cement/sbr primer on sand cement bed.
So joint size then?Posted 2 years ago
5mm is tight. I doubt it will last more than one winter, you just won’t be able to consolidate it properly in the joint. Some of the epoxy hose in types are good. I used it on my Indian sandstone. Prep is the key tho as it’s **** expensive so you really only want to be filling the joints and not any voids. There is a guide on the tub and I’m sure that recommends nothing less than 10mm for that type of pointing.Posted 2 years ago
Ok cheers, it would be good to match joint size throughout, I rally dont want 15-20mm gaps in the house. So will try for 10mm throughout.Posted 2 years ago
