The Portuguese Environmental Geotechnics Commission (CPGA) was created in 2012 by the Portuguese Geotechnical Society (SPG), to which it belongs, in substitution of the Technical Commission for Waste Recycling in Geotechnical Works (CTVROG), which was created in 2003. The reason for this change was related to the need to widen the scope of the original commission, including the development of knowledge regarding Environmental Geotechnics; dissemination of studies, research and overall work regarding waste embankments, contaminated soils and groundwater and their remediation, environmental geotechnics in an urban context, waste recycling, functional geomaterials and environment, shallow geothermal systems, circular economy and sustainability, and another emergent related topics; and finally the collaboration with similar national and international institutions.

To achieve its goals, the CPGA should address the following:

  • Insure, as entrusted by SPG, the connection to technical commissions somehow related to Environmental Geotechnics, belonging to other organisations – in particular IAEG, ISRM, ISSMGE and IGS, which are represented in Portugal by SPG;
  • Organise conferences, technical meetings, lectures, and training courses at the national and international levels;
  • Promote conferences or support by similar organisations; Disseminate related studies and research through national and international conferences, organised by CPGA or promoted by similar organisations;
  • Make available national and international related documents and overall technical information;
  • Keep this website updated with all the information regarding related conferences.

The CPGA regulation, approved at the General Assembly of the SPG on March 20th 2013, stipulates that all SPG associates members of the CPGA provided they request it in writing to the respective Board. Furthermore, students with Bachelor, Master and/or PhD degrees, or professionals who do not work specifically in the field of geotechnics, may request to be enrolled only in CPGA and be exempted from SPG membership, paying the annual fee and subscription established for CPGA members.

The folder “Collaborate with SPGA” on this website aims to promote the interaction between the CPGA members and the Board, taking advantage of their contributions and suggestions to improve the commission’s activity.


CPGA Regulation was approved by SPG general meeting on the 20th March 2013.
