Complete guide to professionals and amateurs –

The brick is an ecological construction material, used in various works due to the extensive duration, of thermal insulation and aesthetic aspect. Discover in this article what are the advantages of the brick masonry, but also the challenges that a professional or amateur manufacturer can face. Also, find out what the solution recommended by a macostter for the humidity of the ascension is.

What are the advantages of the brick masonry?

Brick buildings have many advantages such as:

• Mechanical resistance and durability – the brick walls resist impeccable decades, even in hard climatic conditions; However, an element that affects this material is the infiltration of the water, the problem which, however, has some very simple solutions and we will speak below in the article;
• Fire resistance– the brick is much more resistant to fire than other building materials due to non -flammable products from which the production process is made of high temperatures;
• High degree of thermal insulation – check the technical sheet of the products the values ​​for thermal conductivity (they must be as low as possible) and for the thermal resistance R (it must be higher);
• aesthetic appearance – The brick walls left apparently have a special appearance and can be integrated into internal and external provisions.

The challenges of the brick masonry

The brick has a mechanical resistance, but it is sensitive to water. In particular, it is an absorbent material, which has capillarity. This is a natural phenomenon, characteristic of thin pipes or porous bodies and which can cause an ascending liquid movement.

Simply, if the water comes into contact with a brick masonry, the humidity «rises» through the walls. This is a serious problem and aesthetically, technically and hygienic:

• aesthetically – infiltrations in brick damage the finishes (Gyleum, paint, etc.), on the entire portion in which the water was absorbed; The restoration of the finishes is recommended only after solving the infiltrations (wet walls), so that the problem does not repeat the investment in renovation is not lost;
• technically – the mechanical qualities of the bricks are reduced by prolonged exposure to water; Unlike concrete, which does not lose its mechanical properties if it is moistened, the brick is ground under the action of the infiltration, which leads to a loss of resistance to the construction;
• hygienic – the ascending humidity that occurs in the brick can lead to the appearance of mold and hygrasia that creates an unhealthy climate in the house; Among the negative effects there are the unpleasant smell and favor the propagation of microorganisms due to the humid environment. These can lead to allergies or series of respiratory conditions.

How do you plan that water infiltrations in brick?

To resolve brick infiltration, it is necessary to block the ascending humidity. A product that reaches this is the impermeable injectable injectable Sikamur injection. Penetrate the wet wall and refuses the water forming a resistant barrier that breaks the capillarity and blocks the infiltration.

Most of the time, this is the only product that can be applied, because the walls inside the infiltration house cannot be hydrodic. Therefore, the only practical solution is the injection of a substance that blocks infiltrations. The injection cream can be applied on all types of masonry and, by default, on:

• brick masonry – in old buildings, in the buildings of the heritage or from the period between the two wars;
• brick masonry with objectives;
• Irregular masonry of stone or broken bricks.

Advantages of waterproof waterproofing for brick walls

Choose the Sikamur injectable waterproof to block the infiltration from the brick masonry due to its advantages:

• The product is prepared and is easily applied with a salami type cartridge pistol;
• It does not require double perforation and waiting times to absorb the material, as in the case of other infiltration products;
• Consumption is easy to estimate; Add 10% losses to the quantity suggested in the technical documentation of the product.
• It does not flow and does not stretch on the walls, which helps you maintain a clean work area;
• It does not lead to damage to the masonry, because the perforation holes are made in the joints, not in bricks.

How to apply the injectable waterproofing?

Subsequently, we have prepared more information and useful suggestions for the correct application of injection waterproofing:

• 12 mm Trapani holes in the masonry joint, 15 cm high compared to the level of the floor; The holes must be at a distance of 12 cm from each other;
• The depth to which the holes are perforated depends on the thickness of the wall;
• In the case of double brick walls, it is recommended to perform the treatment with injection cream on both sides of the wall, as if 2 independent structures; If this is not possible, pierce a deep hole, so that the injection is made in both walls;
• In the event that the wall is made of broken bricks or natural stones, a line should be followed that is close to the 15 cm quota compared to the floor;
• If the wall is built in stone with porous structure, such as tiles, it is possible to create the perforation holes in the material, not in the joints;
• If the wall is not uniform and has variable thicknesses and fried particles, which detach and cover the perforated holes, it is recommended that the wall is treated with a treatment with cream injection on both sides; Therefore, the injected product can create a uniform barrier.

Here are other important details you know:

• Hidroizolatia injected by Cream if he tries to the temperature of the plague 0 degree Celsius;
• Temperatures should be positive at least 48 hours after applying injection waterproofing, so that the product works correctly;
• After the injection, the perforation holes can be blocked with products of the repair mortar range;
• If on the surface of the wall, in the injection area, white spots appear, you can easily clean them with a rough brush.

Application of steam permeable materials

After solving the infiltration, the wall should be restored with steam permeable materials that allow you to evacuate the remodeling humidity. Therefore, we recommend Gles and lime -based plaster, such as those in the Mapentique range, for the restoration of heritage buildings.

For the finishes, the products that allow brick masonry, as in the case of silicate paints are indicated. After the wall has been restored, the room must be correctly ventilated, of course or with the help of dehumidifiers. This allows the evacuation of the vapors generated by the humidity of the resignation.

Types of bricks for masonry

Before presenting, briefly, the types of products for which you can opt, find out what brick is: a construction material made with a mixture of clay, sand and water, which can be enriched with other materials; It is burned in ovens at temperatures greater than 800-900 degrees Celsius.

What kind of bricks can you use at home? Here are the options on the market:

• brick with objectives: it has good thermal and solid isolation properties due to the shape with empty spaces;
• BRICK FULL – It has no good thermal properties like the one with holes, but it can often be used for thick walls or as a material for aesthetic finishes.

It is also important to know what the bearing brick means: this product has increased resistance and is used for walls or elements with a structural role.

Execution of the brick masonry

For the correct lifting of the brick walls, it is necessary to take into account the specifications of the project: the positioning of the walls, their thickness, the type of materials used, etc. Subsequently, we will answer a series of frequent questions.

• How to build brick? For greater stability, it is advisable to place the waitresses (classical masonry, hunger, English, etc.). In addition, the bonds can be made in length, in width, block, cross, in a triple layer
• With what material is the construction of the brick? You need a mortar for masonry. The thickness of the horizontal joints should have about 12 mm and vertical ones can have 10 mm.
• What do you cut the brick? You can use a saw with a brick canvas or a segmented diamond disc cut.
• What is brick painting? The wall can be finished with an internal or external washable paint after applying a plaster. If you have applied the treatment of injection cream to block the capillary, it is necessary to use products that allow the wall to breathe and allow residual humidity to evacuate.

In order to benefit from the duration and other properties of the brick masonry, resolve the problem of infiltration as soon as possible. Therefore, it avoids the formation of hygrasia and mold, but also the deterioration of the finishes.
