Building on soft soils has been an increasingly common practice, considering the population growth around the world imposes the need to improve country infrastructure by tailoring and securing spaces to accompany such growth. There are numerous studies related to the reinforcement of this type of soil, seeking to discover new technologies and to improve existing techniques. This approach helps the engineer to make a better analysis of which solution is most appropriate for a given situation. Here we present a review of the geotechnical solutions used to mitigate the problems of settlement and rupture that affect soft soils when subjected to excessive loads, reporting application conditions, performance and benefits or executive problems. Data collection was done at the CAPES / MEC Portal of the brazilian government for the period 2012 to 2017. The results showed that some methods can be applied together and the prefabricated vertical drains (PVDs) are the most widely adopted technique, followed by geosynthetics. As well, it was also concluded that Asia for the continent with the largest number of studies on soft soil construction and highways are the main purpose of this type of work.
