Waterproofing and reinforcement injection works

Main objective of waterproofing of underground civil structures is the prevention of deterioration
of building structure by groundwater. But unfortunately it often happens that the Contractor violates the rules of execution for a proper workmanship for waterproofing, and the question
of repairing waterproofing arises.
  • What is to do in such a case?


    The most reliable option is to reapply waterproofing.
  • Re-application
    of waterproofing material

    Re-application of waterproofing material to underground structures is difficult
    and extremely costly.
  • An alternative is the injection waterproofing method

    Allowing to perform the works from
    the inside of underground structures
    at any time of the year.
How injection waterproofing works:
1
Before the start of waterproofing work, a visual inspection of the supporting structures
of underground structures is carried out and a plan of the necessary work is drawn up.
2
Depending on the condition and materials used during construction of the underground structure, the type of injection mortar composition (BASF) is determined
3
Before injection works are carried out, the surface needs to be cleaned and exposed using HILTI equipment (grinding machine with a diamond cup attachment and local dust extraction) and cracks need to be expanded with the use of HILTI equipment (angle grinder with diamond disc attachment and local dust extractor).
4
Аfter cutting, the cracks are filled with a water stop compound (Emaco)
