The need for waterproofing

Modern construction standards oblige developers to carry out work related to external waterproofing of parts of buildings and structures located underground. Thus, for example, before closing the pit, waterproofing must be applied from the outside of the basements of buildings, underground passages. This insulation method creates the effect of "pressing" the protective layer against the outer part of the structure, which additionally prevents the penetration of water. Installing insulation inside buildings leads to the opposite, “squeezing out” effect, which over time affects the insulating properties.

Today, the highest quality and most reliable protection against water ingress can be achieved by applying the method injection waterproofing. This method appeared quite recently, but, nevertheless, most experts confidently consider it the best method for isolating underground structures of buildings and structures from water.

Advantages of injection waterproofing

Compared to other methods injection waterproofing has a number of advantages:

Significant savings during repair and construction work:
- a) insulation can be repaired in local areas.
- b) the amount of work is minimal both in terms of time and means.
- c) there is no need to stop the operation of the object.
- d) there is no need for ground work in case of underground waterproofing.
The method is applicable at any time of the year.
Waterproofing is monolithic - it has no seams and joints.

Injection waterproofing - all-weather,
performed from inside

Features of injection technology

This method involves drilling through holes in the surfaces of structures. Through these holes, using elongated packers, an injection solution is pumped under high pressure onto the outer part of the structures. The compositions of insulating solutions are different, their choice is due to the water-absorbing properties of the surrounding soils. To fill voids of large volume, fine-grained compositions based on cement binders, acrylic gel, low-viscosity polyurethane resin are used. Each composition requires compliance with special rules when working with it, compliance with the temperature regime, the use of special pumps for injection, etc. Solutions for injection have different ability to respond: slow, fast, instant.

The most effective and practical in terms of quality and price, according to many experts, are the polyurethane compounds PeneSplitSeal and PenePurFoam. They are resistant to physical stress, plastic. In the process of interaction with water, they polymerize. They are hydroactive. Polyurethane compounds are used in the waterproofing of wet and dry cracks, as well as for the permanent sealing of moving openings.

In addition, the injection method makes it possible to completely protect the outer part of the building wall during work from the inside. Sometimes this method of waterproofing is called "veil". Veil waterproofing is carried out using polyurethane material using a one-component pump. After the preparatory work and marking the drilling of holes, through holes are directly created at an angle of 90 degrees.

Waterproofing by injection involves the introduction of special polymers into the body of the repaired structure. These can be hydrophobic or hydrophilic materials.

Such polymers (sealants) are pumped under pressure up to 500 atm.

Injection works materials penetrating from the inside is a technological process that is carried out using special equipment, reliable sealants and experienced craftsmen. They allow to significantly improve the operational terms for any buildings and construction structures.

One of the most common foundation wall problems is cracks. Foundation cracks can be minor or major in terms of structural failure, depending on the location, size, and direction of the crack. But even a slight, less than a hair-thick, crack can contribute to water leakage. And a small movement of water (infiltration) through a crack can expand it, and if it is not "treated" with punctures - injections, problems with the foundation will make themselves felt.

Horizontal waterproofing

Horizontal cut-off of capillary moisture, elimination of moisture suction, filling cracks in concrete and masonry (injection of cement slurries), blocking groundwater with active backwater - we have been doing these works every day for 11 years. That is why we will deal with any such problems in the shortest possible time and as reliably as possible.

The increased humidity of brick or rubble masonry in old buildings often makes itself felt. In some cases, these problems may also occur in new buildings. It is necessary to professionally solve this problem and start the reconstruction of the building as soon as possible. Restoration of wet masonry by injecting the required polymers is a widely used method. In contrast to mechanical methods of masonry restoration, pressure injection waterproofing does not require significant intervention in the structure and is therefore building friendly.

Impregnation (anti-capillary) waterproofing

Injection waterproofing can be conditionally called impregnating.

The impregnating waterproofing device involves the introduction of special solutions or melts into the waterproofed surface, which penetrate and clog the pores, thereby isolating from water penetration.

Why is impregnation waterproofing needed?

The main purpose of impregnation is to increase the density of the surface layer of the protected coating, make the coating waterproof and weatherproof the entire structure as a whole. The use of this method makes it possible to increase the frost resistance of concrete, ensure the corrosion resistance of surface reinforcement, and protect surface layers from weathering and other damage caused by atmospheric factors.
The efficiency of the process is determined by the depth to which the special solution penetrates. The greater the depth of impregnation, the more effective the protection against water penetration.

Every year the development of human civilization is moving in a forward direction, and this development in various areas of human activity is progressing exponentially. This applies to such sectors of the economy as energy, industrial and housing construction, transport and special construction, etc.

The vast majority of objects under construction have buried part or completely underground. In this regard, the relevance of reliable waterproofing is becoming increasingly relevant.
However, it is not a secret for anyone that in practice it is almost impossible to meet an object where its protection against moisture would be made without defects. There are many reasons for this - these are errors in the project and the quality of construction, and of course, unreasonable savings, especially in the application of injection waterproofing technologies. As a result, what was considered secondary at the construction stage, comes to the fore at the stage of commissioning the facility and its operation.

This situation Today it is very typical, which causes enormous damage to our economy, leads to a delay in the commissioning of facilities, a decrease in the period between repairs, their service life, an increase in operating costs and can lead to emergency situations and even to the impossibility of operation and leads to an increase in lost profits .

Most often, in buried and hydrotechnical facilities for various purposes, leaks occur through working and expansion joints, junctions and interfaces of structural elements, utility inlets, formwork attachment points, etc.

Effective fight against such leaks- namely, with the help of injection waterproofing, the main specialization of our company INJECT LLC, which was created in 2007 in partnership with our German colleagues and partners Minova CarboTech GmbH specifically to meet the challenges of the most advanced and efficient method of repairing leaks and waterproofing.

The video shows: Educational film. Practical training in injection waterproofing for the injection of acrylate gels. Taken in Samara (Russia) metro station Moskovskaya (2008). Training is conducted by Heinrich Arnold (Germany).

With strong technical support of our German colleagues, already in 2008 managed to win a significant position in the market of waterproofing services (injection waterproofing) because the demand for such services, due to its effectiveness, did not decrease even during the crisis of 2007-2009! On which the period of formation of the company fell.

The point is that the method injection waterproofing, despite its "high cost", it often turned out to be very effective and reliable in comparison with more "cheap" technologies, and most importantly, it solved several problems at once.

Today, in contrast to the "zero", when in Russia the technology of injection waterproofing appeared no one needs to prove its effectiveness. So how does injection waterproofing, this technology compares favorably with other waterproofing methods, and why has it gained so many fans so quickly?

See what it allows:

Allows you to arrange or restore external waterproofing from the inside. That is, without external excavations.
Allows you to repair and stop the water inflow locally, preventing water from entering the structure.
In most cases, injection waterproofing is repairable.
Allows you to heal cracks and restore the bearing capacity of the structure in its thickness.
Allows you to create volumetric waterproofing, to deal with loosening, while increasing the bearing capacity of the structure.
Allows you to restore the performance of expansion joints located in hard-to-reach places, etc.

Today it's hard to imagine, how a few years ago we did without this "lifesaver". Injection waterproofing has found its consumers as private traders during construction:

foundations,
basements
pools,

and in residential and industrial construction, as well as the operation of objects for various purposes. These objects include:

Moskollektor,
Moscow subway,
Moscow Metrostroy,
Gormost,
Vodokanal,
other hydraulic structures,
HPP, Railway and car tunnels,
pools,
underground parking lots, etc.

For ten years of existence of LLC Inzhekt, with our materials and with our participation, many iconic objects were completed throughout the country, which unequivocally confirms the fact that injection waterproofing allows you to successfully deal with leaks, including pressure ones, and its use is absolutely justified.

If done market overview of products used as injectables, then the first place in terms of volume (but not in importance) occupied by polyurethane resins. Not infrequently, hydroactive polyurethane resins are used for this purpose, foaming on contact with water and, expanding, they clog cavities, providing temporary waterproofing. Along with the undeniable advantages of these resins they have a significant disadvantage- not long service life.

As a rule, after a year, and sometimes even earlier, leaks form again in the repaired areas. The fact is that in most cases we use one-component polyurethane to localize leaks. The catalyst (accelerator) often mistaken for the second component is not.

The second component for them is water, without which the polymerization of "one-component" resins is not possible. Such polyurethane resins are intended only for temporary stoppage of leaks and are completely unsuitable for long-term waterproofing.

Another common mistake the use in construction of injection materials intended for other tasks, for example, intended for use in the mining industry, is considered! It should be borne in mind that in mining, other requirements are imposed on materials and other priorities are set.
So, as in construction, such high requirements for the quality of waterproofing, as well as increased requirements for the physical and mechanical properties of resins, are not set. It is no secret that the properties of polyurethane depend on the foaming coefficient, which is strictly limited in resins intended for construction in order to obtain a denser structure. For the same reason, injection materials for construction have a significantly different pore structure, which leads to longer service life.

In order to provide the tasks necessary specifically for the construction industry, special, more expensive raw materials are used, in addition, the use of phenols is prohibited in injection materials used in construction.

"Low" price of building injection materials should alert consumers.
Another important group of injection materials for injection waterproofing are acrylate (polyacrylate, methacrylate gels). They are indispensable for the construction of expansion joints and cut-off waterproofing.
World experience and our practice over the past 10 years has shown significant advantages of injection waterproofing and injection technologies, which are most often used in the most hopeless cases.
OOO Inzhekt is one of the informal leaders in the field production and use of injection waterproofing materials in Russia. Consumers have already been able to evaluate our materials and technologies at such facilities as:

Moscow subway,
Government House ("White House"),
building of the President's office on Myasnitskaya street,
Musical College named after the Gnesenykh
the building of the tennis development fund in Russia,
new Olympic swimming pool on the Leningrad highway,
Zagorsk HPSP-2,
Balakovo HPP,
Saratov HPP,
road tunnel No. 2 and railway tunnels No. 3 and 5 in Sochi, etc.

Over the years, we have supplied hundreds of tons of our products to various facilities in Russia. The most well-known products for injection waterproofing include such brands as HansaCryl and Proflex.

Buildings made of concrete and brick are durable, stable, able to withstand strong mechanical loads and temperature changes. But joints remain between the plates, groundwater penetrates into the expansion joints, and any crack in the wall can become a source of leakage. Waterproofing a concrete foundation, masonry or brickwork helps prevent a “flood”. With its help, you can eliminate existing leaks and, by closing the cracks in the plates, prevent the appearance of new ones.

Waterproofing by injection involves restoring the integrity of the system with a hydrophobic material. During the work, a polymer injection is made: a substance is pumped under pressure into the destroyed structure. Varmastroy uses powerful pumps that are safe for concrete slabs and bricks. The advantage of the method is the absence of the need to dismantle structures for the sake of injection.

Varmastroy performs injection restoration of:

working (cold) seams;
expansion joints;
microdefects and cracks;
inputs of engineering communications;
attachment nodes.

The contractor offers a cut-off insulation device. All work is carried out using modern European sealants.

Cold seams

It is technologically impossible to pour all concrete structures at the same time. Molecular tension arises between the old, already frozen, and the new layer. Sooner or later, water begins to seep through the working seam. The liquid destroys the concrete slab and the reinforcement inside. As a result, the strength of the entire structure is reduced.

Defect locations:

flat or ribbed floors;
foundation;
columns;
beams.
