The Riasonda
A geotechnical company with resources, experience, and national coverage.
Founded in 2012 in Macinhata do Vouga, Riasonda operates in the field of geology and geotechnics — from prospecting and field testing to special foundation works. We provide services to public and private clients throughout mainland Portugal, with our own equipment and teams with specialized technical training.
How we work
Own equipment. Teams in the field. Verifiable results.
For over a decade, we have invested in fleets of drilling equipment suited to each type of terrain and methodology. Our teams are led by technicians with training in geology and civil engineering, qualified to coordinate prospecting, in-situ testing, and sample collection.
We partner with certified laboratories for soil and rock testing. The reports we issue are prepared in accordance with international standards and Eurocode 7, Geotechnical Design.
Our commitment
to give the project the geotechnical information it needs.
Each project concludes with rigorous results and a report that supports engineering decisions. Client satisfaction and high technical performance at the end of each project are the goals we share with all those who hire us.
Who hires us?
Offices, construction companies and solar energy developers.
We work with engineering and architecture firms, construction companies, city councils, private developers, and companies specializing in photovoltaic energy.
If the project involves foundations, prospecting, or the installation of structures on land, Riasonda has the resources to provide support.
