Connecting Aco Hexdrain to the gully (also subsidence)

[rafter_01]

Hi All,

Its the first time I am installing Aco Hexdrain in my front drive and I was hoping to get some advice on how the Aco would connect to the gully. See the attached pics.

My intention is to run the aco against the house and connect it to the gully.

My gully cannot go any lower and I am unsure how the aco would connect.

I would really appreciate any advice/responses.

Thanks

You could connect to the large boss on the side of the gulley and it could be done with rainwater pipe -- drill a suitable size hole and same hole in the side of the aco - seal with a mastic sealant . Glue any fittings needed in the rainwater pipe. That should be fine

You can also use the adapter : https://www.drainagesuperstore.co.u...mestic-channel-drain-outlet-end-cap-a15-.html

and cut out the side wall of that boss

So use this adapter and connect to the side of the gully?

Before you go too far, where is the DPC in the wall?

Why is there a gaping hole in the wall, and what are you going to do about it?

The garden has been dugout for a new drive and this has exposed that area. This is underneath the recently built porch.

yes just drill out the blanking on the gully..you probably don't need to take all of it out just a half moon.

but what are the answers?

Slightly off topic, how would you connect Aco hexdrain under steps? Would I use a rainwater pipe cemented underneath the steps connecting both ACOs? So like a U shape connection between the two drains?

sorry I am not a builder. Is DPC what you put between the rows of the stone?

Personally i would use eezee drains as you don't need tees etc, just cut with a saw and make your own angles.

The have low cost adapters for going to round pipe : https://www.drainagesuperstore.co.u...n-socket-outlet-end-cap-with-50mm-outlet.html

Aco do have a round to channel fitment but they are about £22 each.

Other alternatives are just carry on with the channel under the steps and use a bit of plastic to mask off the drain holes.

OK I'll tell you then.

One of your pics shows some bits of slate hanging out of a collapsed wall. The purpose of the wall is to hold the house up

The slate is the DPC. When the house was built it was positioned in the wall about 9 inches above ground level and its job was to prevent damp rising up the wall, and into the house.

Slate does not wear out and it lasts millions of years.

Some ignorant buffoon has raised the ground level against the house so the DPC no longer works. You have got to dig out the ground to restore the correct level.

Possibly your clay gulley and drain were cracked and broken and had been leaking since, I would estimate, 1942.

Your house wall has a gaping hole in it because, I guess, the water leaking out for the last 80 years has turned the ground to mud and washed it away and the bricks have fallen into the hole If the mortar between the bricks was lime based (not cement) then that will also have been washed away. You have got to dig out the mud and reinstate the foundation and the wall. You might be able to make an insurance claim for subsidence.

An alternative possibility is that some incompetent builder has broken away the base of the wall that your house stands on.

You must not, repeat not, cover it up and hope it goes away. It will get worse and more expensive. If anybody suggest silicone injections, rendering, or pouring concrete into the hole, kill them and hide their body in the cavity.

Thank you for the information.

Is not the wall the house stands on, that is the porch foundation that was built a few years ago. It is exposed because we have removed the gully and soil around it.
