The CushionWall II System is a unique solution for high-frequency lateral impact areas, such as severe highway curves. This energy absorbing, longitudinal wall gradually dissipates the kinetic energy of an errant vehicle during a lateral impact, and safely redirects it back onto the roadway at a shallow angle. This cushioning reduces the severity of the impact and helps the driver maintain control of the vehicle, which reduces the risk of secondary accidents. The CushionWall II System consists of a series of interconnected “smart plastic” cylinders that can be customized to fit each specific application. The series of cylinders fits behind a concrete transition from the hazard. During an impact, the reusable “smart plastic” cylinders compress to maximize energy absorption. These “smart plastic” cylinders are made from high molecular weight, high density polyethylene (HMW/HDPE). After a design lateral impact, the cylinders regain a high percentage of their original shape without maintenance or repair.

Superior Crash Cushion Design

Sectional design consists of energy-absorbing, reusable, "smart plastic" (HMW/HDPE) cylinders that fit behind a concrete transition. The cylinders can be customized to fit each specific application.

Redirective Capability

Energy-absorbing, longitudinal wall dissipates kinetic energy, and redirects the vehicle back onto roadway at shallow angle. The cushioning keeps driver in control, reducing secondary accidents.


Crashworthy at speeds up to 70 km/h (43 mph) and at angles as high as 20°, when impacted by vehicles weighing up to 2041 kg (4500 lb).

Easy Maintenance

No expendable components need to be refilled or replaced. 99% Self-Restoring after design impacts.


The CushionWall® II system will self restore after most design impacts, typically regaining up to 99% of its original shape and capacity without maintenance or repair of major components.
