The essence and principles of solving problems of retaining walls using Gradtek technologies

What is the retaining wall?

For more than 40 years, the retaining walls are used to hold the ground array or as carrying structures.For example, those that are needed in the construction of motorways and railways, dam, supports of bridges, sea shafts, dams, golf courses and other classes of structures.

Wall or soil systems are popular because they allow engineers, architects, landscaped and road designers to effectively integrate economically appropriate and constructively reasonable projects in initially unsuitable conditions for the operation of the object.Today there are many variants of wall structures and technologies, including geogrids, segment blocks or plates, wire mesh and bunker wall.

Wall Stability in Soils

The main problem of designing retaining structures was and there are their durability in the soil and water environment in which they are used.Problems begin when aging walls begin to collapse and lose their structural integrity due to corrosion of materials (for example, galvanized steel) or water infiltration, dispelning the supporting soils behind the wall.

From the practice of Europe's engineers, the frequency of failures of the retaining walls is 1-y per 1000-y.The studies determined that the retaining walls are concerned about the "bad engineering study" in the project team.And in particular, in subservation and, as a result, the underestimation of the "water" factor.

Application Граундтек in the repair of retaining walls

At the beginning of the repair process, engineers apply various assessment schemes for the causes and mechanisms of corrosion and degradation of the erected design.Georadar (georadiolocation examination) is often used to detect emptiness behind the walls.

If the soil is gained, then Граундтек is called to fill the void and restoration of the bearing base ability.In consultation with engineers for each project, Граундтек develops an individual polymer injection plan to stabilize "loose" soil and filling out voids to stop the further erosion of soils and / or structures.

During injection, the Граундтек command uses laser equipment to track the slightest movement of structures in all directions.Each operation is calculated so that the wall does not collapse from the material pressure.

Advantages of using polymers when repairing retaining walls

The polymer actually displaces the water from the soil massif and does not absorb it during and after work.After completion of the curing process, the polymer slows down as much as possible further infiltration of water even in non-exposive and non-linked soil.

Using the polymer Граундтек and the method of depth injection, private and legal entities reduce the time and expenses without resorting to the complete replacement of the retaining wall.

I correctly understood that your material, or rather its spread in the ground, can be compared with the roots of trees, with the help of which previously strengthened the slopes from landslides!?

It all depends on the type and characteristics of the soil.If the soil is connected, yes, distribution goes according to the scenario of the fault of the formation and, as a result, education resembles the roots of trees

Injections concern only the foundations?Or along the wall itself it makes sense to carry out injections?

All individual and depends on the specific case.First, you need to examine and determine the current conditions and limitations.

Unfortunately no, the retaining wall can be enhanced with the help of technologies of grained, but the design itself must be erected using other technologies.

Grained materials can be injected into the body of the structure.The range of resins varies up to 40 items depending on the purposes and tasks

In this case, of course, technologies can help, but it is necessary to learn each project separately, given all the data available and possible for collecting and studying

If the wall is in the soil, then it is quite possible.Our material arrange hydrobers in Europe

In such cases, it is necessary to study a specific case and carry out engineering calculations specifically in terms of the situation.It should be understood that it is necessary and better at the place: to remove the reason or work with the investigation

It depends on what task it is necessary to solve.With a fifth wall it is more convenient for solving, however, and without a spot there are opportunities to help
