Oh dear DPM forgotten

[LSB]

Hello 

Please can you advise what we can do about this without knocking down the bit of wall to redo.

 

HID forgot to put in the DPM skirt on this bit of wall (DPC is there) and we are wondering if any of you lovely peeps have any suggestions.

 

For context FFL will be at the block level below the red bricks which will be coming out, they are just there to hold the door frame.  There is another layer of insulation and concrete to go in.

 

Thanks

Angle grinder with a diamond blade, grind out the bed and lap the membrane in then re point it. 
 

I won’t tell anybody if you don’t. 😜

thinking about this, won't that damage the DPC ?

Can't see that - have they forgotten that was well?

Unless it is likely to be very wet there, I'd consider painting in bitumen.

Use Blackjack starting with a diluted (water) coat as it will penetrate cracks and crevices. 

Then a slightly diluted coat over joints and then everywhere, 

and then a full gunge one.

An extra coat over mortar and at the base too.

A tar brush is often best.
