Waterproofing Of Bricks

Brick waterproofing is a popular and very important work for each building, which allows for reliable and long-lasting prevention of brickwork in various structures. In order for the work to give the maximum effect, and the materials to retain their insulating qualities for many years, it is necessary to strictly follow the technological requirements, select only the most reliable components and perform waterproofing work responsibly and carefully. And at the same time, it is necessary to clearly understand the features of brick as a building material with its own characteristics and difficulties.

Why do you need waterproofing of brick walls?

Any building brick – be it red clay or white silicate, solid or porous – is a building material with high porosity. And where there are pores, there is the ability to concentrate moisture. And moisture will settle and accumulate without much dependence on the climatic features of the region. To put it simply, moisture will be everywhere and always. Over time, this will inevitably lead to sad consequences, among which the most unpleasant are:

• Formation of fungus and mold;

• Increased humidity and deterioration of the indoor microclimate;

• Reduction of the thermal insulation properties of bricks, including due to the appearance of cracks;

• Significant reduction in the service life of a brick structure.

As a result, the need for expensive major repairs will become the only possible way to correct the situation. In order not to bring the situation to a critical point, it is necessary to perform professional waterproofing of brick walls.

Materials for waterproofing

Currently, waterproofing materials are divided into the following types:

1. Pasted - roll, sheet or panel materials for waterproofing. Perhaps one of the most accessible and widespread methods of protecting brick structures, as well as concrete, blocks, etc. They are not particularly durable - with the exception of the latest developments based on fiberglass.

2. Coatings are protective materials for waterproofing walls, including brick ones, based on bitumen with latex or polymer hydrophobic additives. To achieve improved antiseptic action, they may contain additional components that block the reproduction of pathogenic flora. Processing with liquid mastics takes a minimum of time and does not require leveling the wall, gives a good result, but is more expensive than roll analogues.

3. Waterproof plaster based on a polymer-cement mixture is a good option for waterproofing, which allows not only to protect brick structures from moisture, but also to disguise external defects. An important advantage is that such waterproofing does not require drying the wall. On the contrary, moisture helps to fix the material.

4. Injection materials are special penetrating compounds for a radical solution to the problem of waterproofing brick walls by filling cracks and microcracks with mortar by pumping it in. Used mainly for repairs, not prevention

The choice of material must be made depending on many related factors - the type of building, what specific element needs to be protected, what materials the brickwork comes into contact with, etc. Experienced specialists will help you choose the best method of protection.

Technology of waterproofing a brick wall

Each of the materials described above can also be called a technology for waterproofing brick walls. However, it is no less important to choose correctly not only what to insulate with, but also which side is more correct to do it from in each individual case.

External waterproofing

When waterproofing brickwork from the outside of the wall, the following work plan must be followed:

• The insulated object is carefully inspected, significant irregularities and chips are removed, after which the surface is plastered;

• Then the wall is treated with polymer-bitumen mastic to improve insulation and fastening of the material;

• Pre-cut rolls or sheets are laid - necessarily in the same direction and overlapping, carefully squeezing out air bubbles and folds. To improve protection at the corners and in places where the walls meet the foundations, technological cuts are made and additionally glued with mastic.

If a second layer is made to improve the insulation of the brick, it must be made across the first.

Internal waterproofing

It is best to carry out internal waterproofing not as an independent work, but as part of a comprehensive solution to the problem - that is, together with external. Experts recommend using bitumen-polymer mastic.

Surface preparation is the same as outside - carefully inspect, thoroughly clean and level out any unevenness. Then you need to apply the mastic - it is best to do this with a roller or a construction brush. Particular attention should be paid to weak points - the entry points of communications and the corners of the structure. After the first layer has completely dried, you can continue working and apply the second layer.
