Application of Void Filler method for restoration of structure

Vikas Suresh Kale

Abstract


In this paper we deals with method of injection
grouting which is useful for filling micro and fine cracks in
structures. So Many times pressure injected crack looked
fine, but six inches over, a new crack developed. Coring of
the existing repaired crack could reveal the new crack
emanates from, and because of, the partially filled fracture at
the leading edge of the epoxy. Can anyone argue, “The more
complete the fill, the more permanent the repair”? and good
luck with trying to rectify an incomplete crack fill. Even if
the pressure advocates had a method, epoxy will not stick to
epoxy. its back to that basic physics law when it comes to
material penetrations, you cant put two things in the same
place at once. If there is moisture in the pore structure,
there is moisture in the pore structure. Nothing will get in
unless the moisture is displaced. Pressure applied to the
crack will not do it. The flow and roll of the repair resin
along the interior walls of the fracture may pull some of it
out but what happens to the moisture? We have found that
