Acrylic resin - a representative injection technology

value and especially injectable formulations

use of such techniques can be very effective to carry out waterproofing and strengthening (amplification) the bases and walls in correcting mistakes and defects (cracks, cavities, etc.) The construction of new facilities, the reduction of the bases and walls inold buildings, subjected to prolonged exposure to a variety of external factors, in other cases.

In Progress uses high-pressure pumps, special valve adapters, called packers and working compositions, pumped via the above items of equipment produced by the through-holes of a small diameter.Advanced technologies in that they make it possible to carry out the work with a high level of quality, the elimination of the causes of the defect and for the rest of the life of the repaired structure.

need Separately noted that thoughtless use of injection techniques alone can not lead to a successful repair.The result can only be achieved through an integrated combination of knowledge and competent engineering solutions when determining the cause of the defect is eliminated.

Also, it should be noted the importance of the correct choice of the necessary equipment and injection material, places its injection.And, of course, should strive for high skills and performance skills of people directly performing all phases of work.

types of injection formulations

resin two-component polyurethane is an excellent material for waterproofing works with bases and foundations of concrete.Property compositions to increase their volume ten times successfully used to create a waterproof membrane, fully protecting the water isolated in this way part of the design.

Moreover, the resin penetrates and fills all voids, leaks and channels themselves for such injections.Polymerizing (grasping), it is a single structure, strengthening the overall high strength and stable properties.

Polyurethane resin (one- and two-component) was one of the first injectable formulations which have been used in waterproofing works.The first successful results gave impetus to research, and for the same purpose were effective and convenient compositions based on polyacrylics.

And now for the qualitative isolation from groundwater is considered the most effective and polyacrylic polyurethane injection resin.Among the advantages of these formulations should be called the ability to set and adjust the time of polymerization.It can be changed by the performer if necessary, from seconds to hours.

Further developments led to the creation of special acrylate gel, multi-component, enabling faster and more reliable to eliminate the flow of water in basements, tunnels, etc. Such gels -. Real "cure" for the emergency facilities.Once used, this tool provides further trouble-free operation for the entire period of existence of the object.

How to use injectable resin?

like acrylic, polyester resin has been successfully used for injection works.For processing pursuing more repair work plan, for example, bonding and filling the entire length and volume of cracks, voids are more suitable epoxy-based resin.

polymerizing, they form a very hard materials with increased strength.Working compositions applied on the normal water providing the necessary high flow resins and adhesiveness.Of the materials used for injection methods are also used ultra-fine micro-cement.They are characterized by fluidity, as used in the filling of cracks, voids around the reinforcing frame, which ensures its enhanced protection from corrosion and other protection from water.

To perform this work, in general, can not do without special equipment (pump), capable of providing materials in injection pressure of up to two hundred and fifty atmospheres.In addition, given that the cost of most compounds is high enough before proceeding shall be conducted serious engineering research and correctly determine the cause of the defect.

On the basis of this study concludes applied scheme of work and the location of the valve adapters.Otherwise the result could be, not the elimination of the defect, and the empty flow of materials and resources.

Among the most common variants of the practical application of injecting resin called experts need to address water ingress under pressure, isolation bushings systems in basements facilities (power utility power, water, sewage, etc.), basements and cellars, tunnels under the ground, a variety oftanks and swimming pools, etc.
