I'm now thinking that this may not really be an issue at all, and I can just go without a fall (or maybe do 1-2mm that won't get noticed) from the wall?

How about putting a channel drain along that wall? I'm guessing that would solve all problems and satisfy building control? It would be a nightmare to install as I'd need to remove the gravel around my inspection chamber etc., but I can probably do it.

That's a good idea but that would make it more difficult when it reaches the paving slabs that aren't shown to the left of the picture that go along the side of the house. I've also completed the sub-base and drainage, so that would be a lot of rework.

I'm doing a patio at my house and around my new extension. My plan was to have a fall going perpendicular to the original house wall, but I realised that it won't actually fall away from the new wall as the fall runs parallel. You can see it in the picture below (both green areas as a...

I'm going to lay some Tobermore kerbstones and have found a pipe going through where they'll go and the pipe is almost exactly at the level where my stones will be laid. I'm wondering whether I can do what I've put in the picture with a lintel to support the cut blocks? Everything will be on...

This is the post that lead me to the back drop. This is domestic. It's rainwater and approx 2.5m in length. https://www.diynot.com/diy/threads/maximum-drainage-pipe-fall-for-rainwater.656984/#post-6247682

Not quite what you're saying. It's a new inspection chamber, so no issues with digging down to it. This web page shows exactly what I'm looking to do and appears to be the same riser in the photo...

It's a round Floplast one https://www.screwfix.com/p/floplast-push-fit-inspection-chamber-riser-450-x-235mm/57228

It's the riser that I need to drill, not the pipe. The 110mm pipe will enter half way up the chamber.

I need to cut into the plastic risers on an inspection chamber and was wondering if/how to seal the pipes (110mm). I'm doing it for a back drop pipe, and it's only for rainwater. Do I just use sealant around the pipe or is there something better?

Pea gravel? I thought that might move too much?

I will be doing a new patio and have dug out in a few places for inspection chambers and drainage pipes. Can I re-use the dirt to back fill if I compact it as much as possible or do I need to use scalpings for everything other than pea gravel immediately around the pipes? I don't want to waste...

I'm laying concrete slabs with sand between the joints. I was wondering how I do the edges, because I would expect the sand to fall out if there isn't something solid there (like sand an cement). I have two ideas at the moment: 1. Contrasting setts and use sand and cement, but the joints may...

There is no 'main chamber'. My pipe is the end of the run and it goes into a neighbors property, so I currently don't have access to any chambers. It requires me adding a new chamber. As the ACO drain is quite close to where the existing pipe is, I would need to dig out most of the area for a...

Maybe I will. I was avoiding that as it will be a lot more money (a whole inspection chamber) and a lot of work (digging down at least 1m deep). I would also probably need to redo an existing pipe with a backdrop as it will probably need a different level for the chamber.
