Don’t be afraid of making horizontal geomembrane seams on side slopes

August 1st, 2018

Over the years, there have been many discussions raising concerns about having geomembrane field seams located horizontally on side slopes. By not allowing such seams, it usually results in many short roll lengths that become either unused or difficult to tailor into the flat area of the project. Stated differently, the installation costs increase accordingly. […]

Estimating live loads in MSE wall and slope design

June 1st, 2018

In formulating a factor-of-safety value for a mechanically stabilized earth (MSE) wall or slope project, a design engineer calculates a ratio of resisting forces to driving forces. This contrast is further recognized when using load and resistance factor design (LRFD), which is in our not-too-distant future. The resisting forces are the soil’s inherent properties (e.g., […]
