Process for reconstructing concrete, steel, brickwork or plastic indentations in the ground comprises applying a polyester-based layer followed by a filling material based on an epoxy resin

摘要

Process for reconstructing concrete, steel, brickwork or plastic indentations in the ground which are in contact with materials that damage water comprises mechanically cleaning the boundary surfaces of the indentations (10), applying a filling material (24) based on epoxy resin as a barrier layer, applying a layer (28) based on polyester after hardening the filling material, embedding a glass fiber mat into the layer (28), repeating the first four steps and applying a final layer (36) based on polyester and hardening.
