Injection hoses are used as a planned joint insert for sealing construction joints, butt joints, or block joints in structural engineering, civil engineering, and tunnel construction.
Hose systems show their advantages not only in heavily reinforced components or in complicated geometries.
In addition to conventional joint sealing systems, they can also serve as an additional “insurance policy” for leaks in the joint that occur years later, which can otherwise only be sealed with much greater effort.
In simple terms, in an injection hose system, a hose perforated with special slots is applied to the area of the subsequent joint using clamps before the concrete is poured, the ends of the hose are closed and stored so that they are still accessible after pouring.
Injection of grouting hoses with acrylate gel
The systematically installed injection hoses into the construction joints get grouted after the atrophy of the concrete is finished.
The first set of concrete is presumed. During the shrinkage process of the concrete, a joint is built up around the hose, which secures successful grouting of the same. These problems appear while compacting the fresh concrete, resulting in gaps and cavities that can be combed out.
Acrylate gel is characterized by a high elongation at break, high mechanical stability, and rubber-elastic behavior. Therefore, it is used for veil, surface, or crack injections and compression of injection hoses.
Injection of grouting hoses with polyurethane resin
Represents an effective method of improvement of mechanical and sealing properties of soil and rock environment and constructions, hardens and connects the disintegrated parts of the rock mass or grains of loose material.
Polyurethane grouting technologies spread significantly from mining applications to civil engineering and geotechnics. .
The principle of grouting technologies is the injection of liquid grouting material into the rock environment or construction under pressure.
During the grouting process, fissures and pores are filled with the grouting material, which subsequently.
