Penetron waterproofing is one of the most popular materials in the construction industry. It is produced in the form of a dry mixture, which includes quartz sand, specialized albolite and chemical modifiers. A composition is used for waterproofing reinforced concrete and concrete surfaces of structures. Penetron increases the resistance of buildings to moisture, low temperatures, acids, alkalis, groundwater, sea and sewage.
Scope of waterproofing Penetron
The insulating material can both play the role of an independent composition, and can be applied in combination with other auxiliary mixtures from a similar series of products. The specific application depends on the type of construction.
Penetron penetrating waterproofing is used when there are cracks on the work surface with a width of 0.4 mm. If the size of the defects is more significant, then the Penecrit composition is also used. Both mixes eliminate cracks, joints and wide joints.
The advantage of Penetron is its radioactive purity and environmental friendliness. Waterproofing is completely safe for the environment and human health.
The composition for waterproofing monolithic and prefabricated structures of concrete and reinforced concrete is used. The surface treated with such a composition better resists moisture, aggressive agents, its strength and frost resistance increase.
The advantages of building mixtures
Penetron waterproofing is today considered one of the most effective methods of protecting concrete from moisture.
Among the advantages of the composition are the following facts:
- Penetrating waterproofing is not subject to mechanical wear, as concrete acquires all the insulating properties. The service life of the coating is equal to the service life of the structure on which it was applied.
- More technological way of application. For example, the waterproofing of the Penetron foundation can be carried out on either side - the penetrating properties of the mortar will do their job without drying the concrete itself.
- Dry building mix is able to close cracks forming during operation in concrete with a width of not more than 0.5 mm. When seeping into the pores of the base of the water, crystals build up that expel moisture.
- Penetron does not alter the physical properties of the concrete mix — strength, mobility, setting time, and others. An exception is water resistance.
Proprietary Penetron solutions help even in cases where similar mixtures fail.
The principle of penetrating waterproofing
A liquid solution for insulation is applied only to the wet surface of concrete. Interacting with the base material, the mixture creates a high chemical potential while maintaining a lower potential of the internal structure of concrete. The resulting osmotic pressure contributes to the penetration of the Penetron deep into the material of the insulated structure.
The higher its humidity, the faster and more efficient this process will be. Waterproofing components are able to penetrate deep into concrete structures by several tens of centimeters.
Unique properties of Penetron
Penetrating mixtures have certain characteristics that greatly simplify their use and increase efficiency.
- Such solutions are applied to both wet and dry surfaces. Preliminary drying of the base is not required, which saves money when performing work.
- Special surface preparation before applying Penetron is not required.
- It is possible to apply waterproofing on any brand of concrete. In addition, she reacts not only with him, but also with reinforcing components.
- Environmental cleanliness and safety of waterproofing allows you to use it for the treatment of tanks with drinking water.
Surface preparation
Before applying to the concrete surface of the solution, it is desirable to clean it from sand, dirt, dust, old paintwork and decorative coatings. For this purpose, you can use special equipment that delivers a stream of water under high pressure.
Concrete cleaned from dirt and dust is washed with a weak acid solution and left in this form for one hour. This is done to eliminate fatty traces and accumulations.
It is worth remembering that the best effect of Penetron waterproofing can be achieved if the entire structure of concrete is soaked in a solution and applied to a damp surface.
Penetron waterproofing: application technology
The process of processing concrete structures is started after the surface is completely cleaned of dirt and the necessary amount of mixture is prepared. Penetron waterproofing is applied in two layers with a brush made of synthetic fibers or a special spray.
As mentioned above, all work is carried out only with wet concrete. The first waterproofing layer is applied immediately after the surface of the structure has been moistened with water. Then they wait some time so that the composition “seizes”, after which the concrete is again wetted and a second layer is applied.
The main requirement is the uniform distribution of the composition on the surface of the structure, without gaps and gaps. On average, about 0.8-1.1 kg of the mixture will have to be spent on one square meter of area, but the presence of defects and surface irregularities can significantly increase consumption. Penetron waterproofing is often used in conjunction with Penekrit and other materials from a similar line, which can eliminate leaks, seams, joints and joints of block structures.
Penetron waterproofing: reviews and approximate cost
Before buying any building materials, it is important to ensure their quality. You can do this by looking at reviews from real consumers. Waterproofing materials of the same line receive mostly positive feedback, including Penetron dry mixes. The price of these building materials is perhaps the only item causing dissatisfaction.
If we compare the cost of laying an adhesive type of waterproofing, taking into account its operational life, then the cost of purchasing a dry mix will not be so great.
On average, for one package of Penetron waterproofing, the price varies from 200 to 300 rubles.
Maintenance of structures treated with waterproofing
For three days after applying the composition, the concrete surface must be protected from mechanical damage and impact. The base also should not dry out - this can cause cracking and peeling. To avoid this, you can spray water onto the surface with a spray gun or cover it with plastic wrap.
In most cases, concrete structures are finished with decorative materials. When treating surfaces with Penetron waterproofing, subsequent finishing work is possible only after 28 days.
