<p>The invention relates to a process for repairing and reinforcing the elements made of pre-stressed and/or reinforced concrete which present various cracking levels. The process consists of the following stages: cleaning up the surface of the old concrete (1), by removing the non-adhering exfoliated concrete or the dirt, applying, by polishing plaster coating, a first layer of polyester putty (2) obtained by mixing a quantity of thermally rigid polyester resin with a quantity of cement powder, in a gravimetric proportion of 50% each, applying, by pressing, a layer of fabric or felting made of glass fibers (3), applying by polishing plaster coating, a second layer of polyester putty (2), followed by successively applying a layer of fabric or felting made of glass fibers (3) and a layer of polyester putty (2), up to obtaining the thickness established by the strength calculation.</p> |
