Recently, an innovative ground improvement method known as microbially induced calcium precipitation (MICP) has been proposed as an alternative to conventional ground improvement techniques. Having numerous advantages such as being environmentally friendly and promoting sustainable solutions, MICP has been studied by researchers from various civil engineering sub-disciplines to solve problems related to crack propagation of concrete, insufficient soil strength characteristics, soil erosion, asphalt cracks, etc. This study aims at moving MICP one step further by introducing a hybrid approach that combines MICP and geotextiles to produce a good quality product for reliable field use. Within this scope, MICP is applied on non-woven geotextiles. Physical (imaging) and mechanical (puncture resistance) properties of non-woven geotextiles subjected to MICP treatments under soaking conditions are investigated. Puncture resistance tests are performed and the details of laboratory work including specimen preparation and MICP treatments are presented in this paper. This study, together with its implications for future works, also highlights the next steps to be taken for properly using the MICP method when other geosynthetics are used. |
