Damp rising as far as the dpc

[joella]

Hi guys,

I finished my patio a couple of months ago...you may remember as i made a couple of posts at the time.
I used Rompox for the pointing, including the gap bettween the flags and the house.
It seems to soak up the waterr when it rains, and then that transfers to the brick on the house.
Now i am well below the DPC, but the water seems to travel up the brick as far as the DPC (where the black plastic stuff is bettween the bricks.
Is this ok, or do i need to do something about this?

thats what the DPC is there for
ideally water should have a slight fall away from the house,about 1:60 ,but sound slike the dpc is doing its job

Yeah it does have a slight fall away, but i think the rompox absorbs some of it before it falls away and then transfers it to the brickwork.

I guess i just wanted to know whether replacing the joint by the wall with some mortar rather than rompox would be necessary. From your comment, it doesnt sound like it is.

thanks
Joel

check your cavities and ensure they are not blocked above dpc, and if they are clear your dpc is ok, and water will not penetrate higher.

below your dpc level are the bricks engineering ? if not i would treat with a sealent but only when totaly dry . done lots of jobs where frost has blown the face off and had to replace.

sealing water in compounds the problem james, a brick actually lets water evaporate over time
if you seal it the water stays in there and then freezes and blows the brick.
make sure your gutters dont leak joel,thats a major cause IME

LLL please read my post . Not trying to teach you to suck eggs

i stand corrected
but i am shocked after being taught 1 way for 20 years i.e. high cement content,water seal etc.
in the last 5 yearsthe latest thinking suggests that that type of remedial work does more harm than good
i shudder when i think of all the houses i have pointed in 3:1 mortar and painted with waterseal
:O :O :O
