What cell can form a flat water proof layer?
A cell which can form a flat, water proof layer known as the cell membrane is called the epithelial cell.
What are properties of a cell membrane that allows particules to pass through it?
Note ... the property of a cell membrane is that no particles can pass through it. At least not unaided. Cells have (make) specific proteins that are embedded within the membrane to pass materials back and forth. Due to the construction of a cell membrane (fat on both sides of a monomolecular layer of water) only molecules that are soluble in both lipids and water can get through at all.
What is a damp cloth?

Where do you find damp proof membrane in brickwork?
Usually there is a damp-coarse just above the concrete slab or if it is a peered hose about level with the top of the piers.
What is damp proof course in construction?
Damp proofing is waterproofing applied to foundation walls to prevent moisture from passing through the walls into interior spaces of a buildingDamp-Proof Course (DPC) - A horizontal barrier designed to resist moisture rising through the structure by capillary action - a phenomenon known as rising damp
What is Damp proof membrane under concrete slab?
This is a heavy gauge polythene laid under the concrete to stop dampness rising upwards
Full form of dpc in building?
Damp Proof Course is one meaning.
What remedial work can be done to damp proof a basement?
This will depend on the construction of the basement and whether the structure has failed, or there is an existing damp-proofing that has failed. Another factor will be the drainage external to the basement. If the water pressure from the soil is very high because of poor drainage, many damp-proofing systems will fail.
What does DPC mean in construction?
Damp Proof Course. In modern houses it usually consists of a roll of polythene set into the brick/block courses about six inches above the ground level to prevent damp in the ground from being sucked up into the walls. Matt
What is the definition of DPC?
Damp proofing course. A damp-proof course (DPC) is a barrier through the structure by capillary action such as through a phenomenon known as rising damp. Rising damp is the effect of water rising from the ground into your property. The damp proof course may be horizontal or vertical.
Why is damp proofing used in relation to construction?
Damp proofing is used in relation to construction to ensure that buildings are waterproof when they are built. Damp problems can cause major structural problems so ensuring they remain dry is essential.
Is it necessary to use an underlayment if the roof is stripped out with 1 X 4's before putting on the metal roof?
Yes, you need dpm [damp proof membrane] between the two metal is prone to condensation.
What is damp proof course used for?
prevent moisture from caving into a building
What is the purpose of damp proof course?
So moisture seep into buildings
