Every building, structure and building structure needs protection from moisture or harmful effects from corrosive liquids. Insulation is also required indoors with high humidity. The methods and materials with which this can be done are varied. What materials are there? How to choose the right one? What to look for? A review from the editors of the site "bestx.htgetrid.com/en/" will answer these questions. We've also prepared a ranking of the best waterproofing products for 2020.

Material classification
All materials are divided into 2 large groups:
- For the protection of facades.
- For interior decoration.
Interior finishing involves the insulation of surfaces inside the premises in those places where contact with water is possible. External means protecting the facade, plinths and roof.
Waterproof materials are made on the basis of:
- rubber;
- tar;
- polymers;
- minerals;
- bitumen.
There are also all kinds of dry mixes for penetrating insulation on sale.
For each part of the building (roof, walls, foundation, etc.) and under different conditions, a different type of waterproofing material is used.
Main characteristics
Criteria for choosing a waterproofing material:
№ | Characteristic | Explanation |
---|---|---|
1 | Material elasticity | An important characteristic when covering corners, joints and abutments. The material must be flexible enough to cover the surface evenly. |
2 | Mechanical strength | Responsible for protecting the material from loads during construction and operation. |
3 | Hygroscopicity | Upon contact with water, the material does not change its properties and structure. |
4 | Resistant to UV and other weather conditions | The special substances included in the composition prevent the harmful effects of the environment. |
5 | Compliance with the temperature range of application for the climatic zone | The temperature range should be well matched to the climatic zone. |
6 | Vapor permeability | Thanks to modern waterproofing materials, it is possible to remove condensate without passing moisture from outside. Such protection is especially important for wooden structures. |
In order not to be mistaken when choosing, it is important to consider each parameter.
Application methods
Anti-filtration insulation is a comprehensive protection of underground and underwater structures, as well as their elements. It protects against 3 types of exposure:
- Wrapping.
- Water pressure head.
- Capillary effect.
Anti-filtration insulation is used for moisture protection of basements, shafts, caissons, pools, dams, canals, sluices and other structures. Below are the most common waterproofing methods.
Coating
One of the most common methods of moisture isolation.This technique is used both for external work (to protect the house and structures from capillary moisture) and internal (for example, when waterproofing basements). Apply compositions based on bituminous mastics or cement mortars.
The product is applied in 2 or more thick layers, while the thickness of the coating should be between 2 mm and 1 cm.
The advantages of coating bitumen moisture insulation are a high degree of protection against moisture, a good indicator of elasticity, an affordable price and ease of implementation. Among the disadvantages: fragility (at zero temperature, the coating becomes brittle, as a result of which its destruction occurs - such a coating protects for no more than 6 years), fire hazard of work (high heating temperature of bitumen).
In this regard, recently, mastics with the addition of rubber and polymers are gaining popularity, which improve the properties of materials.
Mastics, sealants and bitumen are toxic, so they can only be used on a dry base.
Lubricating moisture insulation using cement mortars also has excellent moisture-protective properties. A striking representative is the two-component polymer modified cement mortar sika top 109. After hardening, the coating retains its elasticity and flexibility. Such a composition is used for moisture protection of foundations, stone and reinforced concrete structures, internal and external protection of pools and other reservoirs. In addition, it is used as a primer for protective elastic coatings.
Oleechny
This type of work involves the use of roll or sheet materials that are glued in several layers using bitumen mastics or synthetic resins.
Materials consist of several components:
- adhesive base, which simplifies the procedure for attaching the material due to its location on the frame (this layer is optional, but it is often found);
- a substrate made of cardboard, polymeric materials, etc., is a frame for applying a protective layer;
- a waterproofing layer on top contributes to moisture protection.
The easiest way to make such insulation is on horizontal surfaces. This method of insulation is suitable for protecting concrete and other types of surfaces.
The curtain should be installed with an overlap of 10 cm to avoid overlapping joints of adjacent elements and subsequent leakage.
Dyeing
Paint-type waterproofing forms a membrane that does not allow porous building materials to absorb moisture. Most often, these are emulsions based on polymer, polymer-cement, epoxy resins or bituminous mastics. Components that improve their properties are often added to the composition. Waterproofing by painting is done with a brush, roller or spray gun. This method is used for interior and exterior decoration.
Bituminous mastics are applied in 2-3 layers, each of which should be at least 2 mm. For synthetic compounds, 1-2 layers of 1 mm thick are sufficient.
In terms of composition, waterproofing paints can be divided into:
- bituminous (emulsions with the addition of bitumen and auxiliary agents);
- polymer (consisting of synthetic resins, rubber-resin mixtures, paint and varnish components);
- bitumen-polymer (based on bitumen and various synthetic polymers);
- polymer-cement (based on polymer-cement compositions, water glass, Portland cement and other similar materials);
- tar-epoxy (thixotropic two-component tar-epoxy resins).
The painting method is used both for external protection of building structures (covering cracks in walls, foundations) and for interior decoration. Moisture accumulates under the tiles and in the places where pipes pass, as a result of which mold appears, and building materials are gradually destroyed.
Waterproofing the walls and floors in bathrooms in case of flooding prevents water from leaking to the lower floors.
Waterproofing plaster
This type of moisture protection is designed to prepare surfaces with a high level of humidity for finishing.These include primarily basements, foundations, basements and exterior walls of houses.
According to their composition, moisture-proof plasters are divided into 2 types:
- Asphalt.
- Cement-sand.
The latter are relatively inexpensive. You can even make them yourself, and the coating procedure itself is similar to ordinary plastering.
Cement plastering is applied in several layers (from 5 to 40 mm.)
Asphalt plasters are more often used in industry. They are not so budgetary, and special equipment is needed to work with them. Asphalt plaster is used in cold and hot (heating up to 180 degrees Celsius) methods.
Asphalt plasters must be laid in 2-3 layers, each layer from 2 to 4 mm.
Penetrating
This method is considered the most popular and effective. The functionality consists in the penetration of the moisture-protective composition into the structure of the material to a depth of 20 cm. Thus, the waterproofing layer displaces moisture, filling all possible pores and microcracks.
Advantages of a penetrating moisture protection method:
- giving additional strength to concrete structures;
- simultaneous repair of all existing cracks;
- no need for a primer and a protective layer;
- increased resistance to low temperatures;
- formation of a sealed and seamless coating.
They use penetrating waterproofing for moisture protection of foundations of different heights, basements against groundwater, pools and other water tanks, bathrooms, baths and underground structures.
The best penetrating mixtures:
- Penetrol.
- Osmosil.
- Hydrotex.
- Hydrochitis.
- Akveton.
- Crystallizol.
- Sprayed
Waterproofing of this type is carried out using a spray gun. Acrylic, bituminous and polyurethane compositions are used as sprayed products. Such protection resists not only moisture, but also the effects of more aggressive substances.
After application, the moisture-proof mixture hardens, forming a durable protective layer with pronounced anti-slip properties. Such waterproofing is durable - protection lasts up to 50 years.
This method is used to protect basements, swimming pools, foundations and roofing works.
Injectable
It is used in construction when it is necessary to introduce an insulating compound into cracks, seams and pores, as well as during repairs. As a rule, the injection method is used along with other types of waterproofing to further strengthen hard-to-reach places.
Resins are used as moisture-protective compositions based on:
- polyurethanes;
- silicates;
- acrylates.
Cement and special emulsions are also used.
Zasypny
It is aimed at protecting the structural parts of the building from water penetration using free-flowing mixtures. When interacting with water, a dense moisture-proof protective layer is formed.
This type of insulation is used to fill any cavities in the foundation, floors and walls. The advantages are high thermal insulation characteristics and durability.
The disadvantages include:
- high cost;
- settling over time;
- the complexity of installation.
The composition of free-flowing mixtures contains bentonite, mineral wool, ash and perlite sand.
