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.
