Concreting over SWA cable

[Pete Verdon]

At the side of my house there's a rainwater drain that, being near the outside tap and hose, tends to also get used as a general drain for waste water (only water though, nothing nasty). However, around the drain itself is basically just mud. I'm considering slapping some concrete around it to form a kind of shallow funnel and to fill in a manky muddy gap between the house wall (below the DPC), the boundary garden wall, and a piece of concrete forming part of a patio (it's a complicated layout). About half a square metre of concrete.

In the same area, though, is a run of SWA that supplies the shed. It's clipped to the house wall, the side of the patio, and then to the garden wall to run down to the shed. This new concrete I'm planning would be poured over part of the cable, so it would come down the house wall into it, then emerge up the garden wall on the other side.

I don't expect to need to modify the cable. Any reason not to just concrete it up as proposed?

Cheers,

Pete

I can't see any reason why not - if you do ever need to get at the cable, it's only 5mins work with a lump hammer to break the concrete up

Might it be worth laying some kind of duct to allow for future additions or mods? N

The problem with such a duct in the "pouring" face of a drain gully is that the duct is likely to catch a fair bit of any water being poured in.

I suppose I could run the ducting a little way up the walls either side.

Mind you, I'd need some kind of split ducting to install it in-situ - I don't want to remove half the cable to feed it into a tube.

Best just slap concrete over the lot, I reckon. The odds of needing to get at that cable are minimal, and any future ones (also unlikely) can take a different route.

Cheers,

Pete

I would be inclined to stick a little bit of packing of some sort around the cable to keep the concrete off the cable itself. Just enough such that if the cable needs to move due to expansion, it is not being abraded and constrained by the edge of the concrete. Does not need to be anything elaborate - a small bit of split sided pipe insulation for example or a couple of bits of wood.
