Avaliação técnica entre métodos não destrutivos e métodos destrutivos aplicados em tubulações de esgotamento sanitário

Abstract

Currently, the rehabilitation sector asserts itself as a viable alternative to new construction. The rehabilitation is not only based on the intervention in the building, but also in underground infrastructures, as well as in wastewater drainage systems. It is necessary for the national market to redirect itself to the maintenance and rehabilitation of buried infrastructure, opposing the construction of new networks. Each time there is a greater number of techniques for the rehabilitation of sewage and waste systems, solving all kinds of problems of these systems, applying in each case the techniques that best suit the solution of the problems. This work intends to show MND techniques and the whole process attached to them, so that it is possible to understand what role they may play in the emerging rehabilitation and maintenance market. In this context, the theoretical comparison is presented between non-destructive rehabilitation methods and destructive methods for analyzing economic and social viability
