Sloped aco

[thewickedpickett]

I recently had a patio paved and a horizontal ACO channel
Installed joined onto an existing drain. It's working quite well however the drainage on the other side of it is now concerning me. It basically runs away down into my driveway. To solve this I want to install another ACO channel joined onto the existing one at 90 degrees.

However it needs to be installed on a slight slope away from the existing channel. Can one obtain internally sloped/compensated channels the opposite way to the natural slope or is this madness? Also is a 90 degrees join in the existing ACO channel a big deal?

There is another option of installing a small ACO channel on the actual driveway linked into a gutter drain to catch the run off water. But this requires cutting a channel in old asphalt and I'm not sure how difficult this is.

hi joining at 90% no problem just cut into side .water will find its own level as long as the back fall is not greater than depth of aco it will work no problem with water trapped in one end .multi depth aco are big £££
