How does the WIPP™ Work?

WIPP Stabilisation Components

WIPP System Explanation

WIPP barriers utilise three main components to operate.

The first is the freeboard, this is the amount of inflated barrier above the water level. A minimum of 25% freeboard is required in all WIPP installations. Freeboard requirements may increase if the barrier is exposed to, or has the potential of being exposed to high water velocities (1 metre per second or greater), slick soils or other relevant hydrostatic conditions.

The second is the surface friction. This stabilises the barrier when exposed to flood waters on one side. Surfaces like roads, concrete, paved areas will have a greater surface friction component. Barriers exposed to soft or slick soils may require additional freeboard.

The Internal Baffle System is the third component, which is an internal patented restraint baffle, which locks into place when the barrier is exposed to greater water pressures on one side. The baffle limits the amount the barrier will roll as the water levels rise. WIPP™ barriers are available in double- and single-baffle styles. The 0.3m through to the 1.2m system heights are made with single baffles. Barriers above 1.2m system heights are only available in double-baffle designs.
