WATERPROOFING AND REPAIR OF UNDERGROUND STRUCTURES
Characteristics of geopolymer resins allow to use them for strengthening and waterproofing of various underground designs. These include facilities such as collectors, mine pipelines, wells, fuel tanks, underground tanks, basements, etc.
If in the course of operation of the ground construction which walls have to provide full tightness, there were cracks or there was a liquid leak, it is necessary to carry out urgent repair of object. However, in many cases it is not enough just to eliminate cracks, replace damaged elements and restore the waterproofing properties of the walls of the structure.
If the structure has leaked liquid, it is likely that there has been a blurring, a decrease in compaction and a weakening of the soil in which the object is located. Therefore, to restore the structural characteristics of the object often need to also increase the density of the soil where the structure is located, that is, to strengthen and strengthen the blurred soil. The easiest way to do this is with Uretek geopolymer resins.
Waterproofing of mines and tunnels
Underground structures such as tunnels, pipelines and mines can be made of prefabricated elements. For waterproofing and sealing of similar constructions it is necessary to carry out reliable sealing of joints and seams between elements. Gelopolymer resins can also be used to seal the joints, which are injected into the joints of the elements.
Seams and cracks in the walls of underground structures can be closed, both from the ground, without the need to excavate structures, and, if there is a possibility of personnel access - from inside the objects. When injecting geopolymers at the point of contact of the outer surface of the tunnel or mine with the ground, the expanding material may even get inside the object, which will indicate the reliability of the work performed. In this case, the excess material is simply cut from the inside of the structure and all internal surfaces are cleaned.
Reduction of soil moisture content
One of the reasons for the violation of the waterproofing of underground structures (basements, foundations, etc.) - insufficient compaction of the soil adjacent to the walls of the structure. Loose soil around the perimeter of the structure can sag and absorb excess moisture, as a result of which the outer walls below ground level will get wet.
To stop this process, geopolymer resins are injected into the backfill loose soil. Thanks to it it is possible to increase density and to strengthen soil that will reduce its moisture capacity. An indirect consequence of such a procedure is also the waterproofing of the structure.
