News and Articles

Geotechnical engineering requires a lot of waiting. You wait on calls, test results, the weather. You wait on a construction activity to finish, on software to complete extremely complex models, on site assessments to be signed off on. You wait in labs and airports, on calls, in lobbies. So what to do with all that waiting? Sometimes, you let the mind wander. It may just take you to geotechnical p... »

Best Practices for Minimizing Geomembrane Wrinkling
