To avoid *rising dump* a reinforced polyethylene film shall be laid over the first layer of concrete blocks.
All brickwork shall be visual brickwork, however installation slots and holes have to be filled smoothly.
The walls have to be even, get coated with a primer and ready to get plastered or painted.
The structure complies with the requirements of local fire brigade.
"Rising damp is the common term for the slow upward movement of water in the lower sections of walls and other ground-supported structures by capillary action. Although rising damp of up to 5 metres in height has been observed[9] the height of rise is typically much lower and is rarely above 1.5m. Rising damp has been a widely observed phenomenon for at least two hundred years. [10] There is also strong evidence to suggest that it was a problem understood by the Romans and Ancient Greeks.[11][12]
"In simple terms rising damp occurs when ground water travels upwards through porous building materials such as brick, sandstone, or mortar, much in the same way that oil travels upwards through the wick of a lamp. The effect can easily be seen by simply placing a piece of porous brick, stone, or mortar in a shallow tray of water and observing how the water is absorbed into the porous material and is transported above the water line.
"Rising damp can be identified by a characteristic "tide mark" on the lower section of affected walls. This tide mark is caused by soluble salts (particularly nitrates and chlorides) contained in the groundwater. Due to the effects of evaporation these salts accumulate at the "peak" of the rising damp.[13]
