Aplicação de material geossintético em drenagem vertical : estudo de caso em obra na cidade de Cuiabá, MT

Abstract

The presence of water in retaining works, without a correct drainage, can make the retained soil unstable as well as the related construction elements; this may cause structure failure and different structural pathologies. The present study aims to highlight the pros and cons related to the placement of a geosynthetic material applied in the construction of retaining walls in a residential worksite in Cuiaba in order vertically drain the water. To accomplish this task a case report has been undertaken based on: bibliographic research, desk research and field surveys. The field surveys have been divided between: monitor the material’s placement and interview questionnaire with field engineers working in Cuiaba, MT. The gathered data allow us to state that the material is widely used by the engineers and presents many advantages such as: fast placement and ease of handling due to the material’s lightness. However, professionals still face some difficulties regarding material availability on the region, unknowledge of the material by the professionals to especify them, as well as the lack of skilled labours to place the material. Therefore, the sugestions to these problems are: to spread the knowledge related to the use/placement of it, the specialization of professionals who are working on this area and workforce training.
