Pigra Engineering studies, classifies and designs solutions for geotechnical related pathologies, raging from slope landslides to foundation pathologies in unique structures or damage to road infrastructure and buildings.


We also undertake auscultation and monitoring control of slopes during project commissioning and operation phases, using state of the art technology like drones and satellite remote sensing. Our highly skilled staff ensures an integral service to our clients, both public and private, providing geotechnical solutions as well as fully detailed analysis.
