Should this Joint be Mastic or have some Damp Course?

[50020]

I have moved in to a new home recently, and I have noticed that a garden boundary wall which adjoins the house brickwork, there appears to be no damp course in the wall, and also, no damp course between the garden wall and the house.

As you can see from the pictures, the joint is mortar. Since there 'appears' to be no DPC in the high garden wall, I would either expect the joint between the house and the garden wall to contain DPC, or, the joint to be made up of mastic.

I have looked at similar properties on the development, and the joint appears to be mastic.

Not being a builder, what would I expect between the walls if the garden wall has no DPC?

I hope I have explained this well enough.

It's cosmetic. A mortar joint will crack as you can see, but mastic will not show a crack. But there is no technical reason why it should be mastic. No DPC required either.

Do you actually have a problem, or just anticipate that you might get one.

The latter, I anticipate I may get one ... I don't wish to wait 5 years for a problem to develop.

What problem do you imagine could occur?

And don't say "damp to the inside" because that wont happen. The rain will hit that house wall just the same if that garden wall is there or not

In fairness I was concerned dampness may creep up the Garden Wall, and across to the house.

You have a cavity wall. Moisture wont get across the cavity - and it it does you have a different problem in any case.

Thanks for taking the time to reply ...

What did the planning officer and building control officer say about it?

Eh? Why would either even be interested?

 

[Nakajo]

Because this is the Building Regs and Planning board

The 'Planning board'? Are you drunk Nakajo? Lot of that going around here lately.

Discussion board

Looks like someone should be posting in the miserable old fart forum instead.

I would, but I'm not miserable.
