Stabilization of Dam Slopes and Spillways

The GEOWEB® system offers economical solutions to dam failure modes created by saturated unstable slopes and stormwater conveyance erosion.  Single or tiered protection systems can be designed to be water permeable or to shed sheet flow, and built as vegetated earthen dams, or aggregate and concrete solutions.  The GEOWEB system also provides flexible, ‘crack-resistant’ hard-armored protection of geomembranes on dam faces with 50% less concrete depth than typical reinforced concrete.

GEOWEB Benefits for Dams and Spillways

  • Maintains strength and integrity when subjected to subgrade movement.
  • For concrete systems, can reduce the depth of concrete by 50% or more.
  • Installs and infills quickly when compared to formed reinforced concrete, reducing construction schedules.
  • Is suspended with high-strength tendons and ATRA Tendon load transfer clips, protecting the integrity of impervious liners.
  • Is quick to deploy, occupies a small footprint in delivery and storage and is easy to handle.
