• Although rising damp of as much as 5 metres in peak has been noticed the peak of rise is usually much decrease and isn't above 1.5m.
• Rising damp is the frequent term for absorption of water within the decrease sections of partitions and other floor-supported constructions by capillary action.
• Rising damp has been a broadly observed phenomenon for at least 200 years.

Exterior walls can have the same problems if they're coated or painted. If you've plain brickwork on these walls, then you may notice that mortar between decrease bricks is coming unfastened or even falling out.
