DPC and engineering bricks?

[Tipper]

Noting that engineering bricks are used in damp resisting situations and also used as a rigid DPC, if a wall of a house, actually the whole house, is built of engineering bricks is an additional DPC required?

I've got a house built like this and can't see a DPC. Should I be worried.

There isn't any rising damp though.

Engineers are not a suitable DPC

i have had to inject quite a few times into these types of bricks,on high pressure but it goes in.

WTF?

 

[^woody^]

YOLO

1. are your walls solid or cavity?

2. why is this an issue?

3. some uk areas often used a facing, blue brick that resembled, but is not an engineerining brick. There's also a blue glazed terra cotta brick, but i doubt that a whole domestic residence would be faced with them.

4. for info: dont now, or in future, allow pressure injection in your brickwork, esp. blue brick, it doesn't work and it looks terrible.

Eh?

Don't know who's right and who's wrong here, but lots of properties have been built with a few courses of engineering brick as the sole DPC.

It does occur to me though, what is to stop damp wicking through the mortar, even if the engineering bricks are impenetrable? I guess a additive could be used these days but could mortar be made waterproof a hundred years ago? Or does the damp not penetrate?

Woody is quite correct, due to the fact that both class A and class B have absorption rate of <7%.

There's no such thing as rising damp anyway. So I wouldn't worry.

Eh?

When you draw up your next set of plans, just specify two courses of engineers and no physical DPC, and see what your BCO friends say

And after 20 or so years they get saturated and the damp appears

and yet again i will ask the question,
if rising damp doesnt exist and never has,then why oh why do they sell dpc material etc.
because surely if this is the case then hey we can build walls or install concrete floors etc without any dpm .

 

[Tipper]

It's all irrelevant anyway as a closer inspection has revealed a proper DPC is included.

Forget it guys...I'm no longer interested!

**** off to another thread then.

I'm waiting for softus to appear
