Moisture – proof materials for roofs walls and floors

Moisture – proof materials for roofs , walls and floors

Can be divided into moisture – proofing material into three main sections:
1 – flexible insulating material .
2 – insulating material semisolid .
3 – rigid insulating material (solid) .

First: flexible insulating materials

These materials are placed on the walls and the walls and floors because they bear a slight decline buildings without being broken.
Can be divided into the following:

1 – metal panels :

These materials are used to isolate moisture from surfaces , walls and floors , and these items:

A . Lead plates : Because lead rustproof it painted face with bitumen material , these panels are placed between the bricks and stone.

B . Aluminum panels : It is the most commonly used materials , as we know , because it does not rust.

C . Galvanized iron sheets .

D . Iron plates stainless steel .

2 – Bitumen :

Is a combination of natural hydrocarbons and bitumen ranges in texture between hardness and semi – rigid , horizontal painted walls and foundation walls in contact with the soil wet ground . Bitumen is one of the most used materials nowadays in moisture proofing because of the cheap price for the rest of the material other than its flexibility and ease of use and resistance to fungi and mites , ants and others.

Bituminous types :

A . Oxidized bitumen ( blown ) : What makes the softness and its ability to flatten and bending is to reduce the ratio of hydrogen to carbon in the molten bitumen and reduce the liquid oils contained in inflating the air .

B . Bitumen dry ( steel ): used when there is a high mechanical loads and low temperatures and turns to the state of rigidity when the expulsion of heavy oils when mixed composition by Bituminous distillation under high pressure to expel those oils.

T. . Suspensions bitumen : these pendants are divided into :
1. Suspensions fixed 2. Suspensions medium consistency.
3. Suspensions low stability by refraction of speed , depending on the speed of the separation of bitumen from the water.
Bituminous and melts at a temperature of 60-80 and placed in drums and placed upon the sand instead of asphalt is used to isolate the natural moisture in the walls or painted horizontal hot fish to reach at least 2.5 mm.

 Some other types of bitumen to resist humidity:

1. Bitumen with Hessian Base.
2.Bitumen with fiber.
3.Bitumen with Asbestos Base.
4.Bitumen with Hessian & lead.
5.Bitumen with fiber & lead.
6. Bitumen with Asbestos Base & lead
3 – waxed polyethylene :
Polyethylene is one of flexible materials that are resistant to buckling impact of falling buildings without light damage , which is black in color and for use as a buffer material should be 0.46 mm thick and weighs about 0.48 kg / square meter. Due to this thickness tarpaulin sheet for bitumen material preferably placed in to welds mortar buildings as well as to isolate the bathrooms and showers .

4. Insulator means of water:

Can rely on this method to prevent moisture from 3-5 years depending on the type of material and how exposure to moisture , this article of the kind with the possibility of isolating only, and makes this liquid substance paraffin to volatile oil as confused mixture brushing or spraying machines spraying private areas of buildings executed the highest water level of the earth ‘s surface .

Second: solid insulation material half :

This material easy installation and configuration in place to be isolated and are used to insulate buildings from moisture more often.
The most important of these materials :

1 – Asphalt :

It is a good buffer to moisture and disadvantages not afford to flatten power higher , especially when landing light , the building of asphalt cracking and damage and be susceptible to water leakage through it, and it would prefer not to put in these buildings only after a special study .
The asphalt has three types: natural asphalt , industrial, Asphalt Mstich : It is a rubber material asphalt .

2 – coil moisture – proof :

Used to isolate the water and moisture in the surface and carpeted surface to be isolated to burn the tape with a special device .
There are other materials insulation moisture sprayed onto surfaces and form a thin layer anti- moisture, and this layer resist also air pollution and resistant to acids, fats and oils, have the ability to withstand temperatures between 40-120 and has the ability to docking on the ceilings and there are several different colors are used as needed.

3. Asphalt coil and a thin layer of metal :

These scrolls are made ​​of asphalt material and the type of metal and aluminum is often used , and placed within the ceilings and walls.

4. Small asphalt chips :

These are used to isolate the slanted surfaces because they are easy to install and resistant to moisture and water

Third: rigid insulation material (solid) :

These materials are divided into :

1 – concrete whites :

Often this whiteness is placed on the foundations of the buildings in the normal soil of two layers each thickness of 0.6 cm, in the case of very wet soil must Bituminous paint on the white concrete layer .

2 – small asbestos panels :

A small cut asbestos has many forms . Mounted on ceilings suitable ride on top of each .

3 – wooden planks and rinse small :

These materials are commonly used in the curved surfaces and walls , but the drawback it is fast fire.

4 – asbestos cement sheets :

And made of Portland cement mixed with asbestos fibers that are wet and then pose to pushing plates, these panels are sometimes used in ornamental curved surfaces . At the present time , to prevent their use after it was discovered that asbestos causes cancer to humans.

5 – plastic layer :

Such as Formica and people prefer to use this article to be placed on the tables and in the cladding walls and furniture .

6 – glazed tiles :

Tile made ​​of ceramic material is good, and is used for ornamental curved surfaces is good to isolate the water, moisture and helps presence on slanted surfaces expel water from them quickly.
And requires the user to be brick fire completely free of holes or cracks , to be a smooth surface and if Nail beaten heard his voice sonorous voice is not heavy because recent evidence of cracks or incomplete brick fire
