3D Cellular Confinement Concrete Revetment System

EPEC is a patented, multi-layer, hard armor revetment system that is used to reinforce and protect surfaces exposed to high water velocities, wave attack, and potential hydraulic jump from super critical flows. This unique engineered system uses a 3D cellular confinement layer and an articulated block layer that work together to increase hydraulic performance and provide enhanced protection to ground surfaces. Each of these layers are separately known and deployed in various environmental applications, but with the EPEC revetment system, they are deployed together for increased performance and protection.

– Eliminates ACB movement

– Greatly improves system performance and reliability

– Only a marginal increase in cost for a more effective system

– Better protects against hydraulic jump

– Easier install as stone is stabilized (won’t get displaced)

– Enhanced quality assurance – guaranteed stone thickness

– Dam overtopping

– Auxiliary spillways

– Levees

– Diversion berms

– Through testing, it has been demonstrated that stabilizing stone under ACB’s leads to large improvements in hydraulic jump stability (2.5 – 3.5X)

– Compared to similar systems with unconfined drainage layers, EPEC showed the following improvements:

– 250% performance improvement in Factor of Safety (FOS) on a 3:1 slope

– 366% performance improvement in hydraulic jump stability on a 2:1 slope
