reg. rising damp: does the dampness rise between bricks and plaster or through bricks. do bricks get wet?thx?

Answer 1

Bricks are impervious.

Dampness can pass through mortar and plaster,especially when it is decrepid.

Often there is a root cause of the dampness that needs to be addressed.

Answer 2

The water rises through the brickwork, it also penetrates through the mortar and plaster. The bricks do get wet, when injecting damp fluid it "chases" the water out and it can be seen bubbling out of the bricks, some bricks are a lot more absorbent than others If it is not addressed right away it can also penetrate into any attached word-work and cause further repairs. After the damp-course has been repaired the inside plasterwork should be removed up to a height of at least one metre and renewed.

Answer 3

Through and between the bricks. The bricks do get wet. The damp stops at the Damp Proof Course.

By the way, the Irish guy above me who thinks rising damp is caused by condensation must have had a few glasses too many already.

Answer 4

What you need to do is to chech where out side the room ie in the garden? outside wall to see if your "air" brick is clear,so often damp is all to do with the brick being either below grond level or blocked also see where the damp course line is,this must be above and clear of the ground.So answer to your question, damp travels through the bricks.

Answer 5

If your house is an old one it is unlikely to have a damp course.the bricks on the inner walls are more than likely "common" brick ,this is porous, dampness rises by capillary action,i.e. it is attracted to the driest part of the wall,
if you have this problem,the only solution is an injection damp course.

Answer 6

Water can "wick" up any porous material but only so far depending on the material. General dampness on material surfaces are usually caused by condensation. If the surface temp is lower then the air temp and the air has a higher moisture saturation then the moisture will condense on the cooler surface. just like on the outside of a chilled mug of beer. Speaking of which. Salute.

Answer 7

Damp risis through bricks as well as plaster,See.www.dydata.com. For latest cures.

Answer 8

rising damp affects all surfaces ..one absorbs and is passed on to the next surfaces etc
