InjectionInjection is the method applied to the repair and restoration damaged, having small cracks / concrete or concrete designs. This repair is necessary as through these cracks porous designs are saturated with moisture, begins to rust and loses as a result durability. Injection is applied to the repair and strengthening which are submitted influence of moisture and the thawing ice of external areas of socle rooms, to a waterproofing and dehydration of surfaces. On the basis of the available experience, we fulfilled a number of the technologies helping effectively and in a short time to solve a considerable circle of problems of elimination of various defects of stone and concrete constructions.
Services in strengthening of designs- device of deformation seams;
- repair and restoration of concrete;
- strengthening of can of elements by an injection method;
- strengthening of can of elements with application of special plates and fabrics from the monodirected carbon fiber and (or) aramide fibers;
- restoration of the bearing ability and the general "geometry" destroyed (to 50%) can of elements and local sites of a surface;
- production of concrete and solutions (in postroyechny conditions) with special properties (high durability, frost resistance, water tightness, fluidity, a tiksotropnost, etc.), with application of the special modifying multipurpose additives.
Technology of injectionIn the presence of big cracks in reinforced concrete designs the method of injection provides good repair. But it is very often heavy to define what will give the best final result - this method or the applied technology of removal of old concrete and its restoration by means of special solutions. If concrete of excellent quality and a rust is not present, and defect of a design resulted from a crack, then it is better not to find injections of a way.
The main operation of a method is introduction of pitch of the corresponding compounding. A large amount of defects, cracks in can designs turns out from the shift, shift, and pitches with big coefficient of elasticity can also lead to emergence of new cracks, near repaired. The choice of the correct recipe is extremely important. Today widely epoxy, polyester and their mixtures use pitches. These pitches possess the acceptable viscosity, viscosity, ability at rather big temperatures to injection, small elasticity, and also coupling with the moistened concrete. The last parameter is very important.
On the basis of the available experience and continuous monitoring of new technical information, we fulfilled a number of the technologies and technical solutions helping effectively and in a short time to solve a considerable circle of technical problems of elimination of various defects of stone and concrete constructions. First of all it concerns waterproofing questions: elimination of a direct filtration of moisture and active leakages, waterproofing of "cold" seams, device of a horizontal gate-type waterproofing, device of antifiltrational veils, etc. Other scope of injection technologies is strengthening of elements of designs.
