OmniGrip HF High friction surface treatment (HFST) to decrease braking distances

OMNIGRIP HF is a high friction surface treatment (HFST) which is a thin overlay applied to asphalt and / or concrete roads and highways to improve surface friction and resulting in decreased braking distances and threshold impact speeds in emergency situations.

Crash Reduction Benefits

A High Friction Surface Treatment like OmniGrip HF is an internationally proven road safety solution. OmniGrip HF is a ‘silent saver’ – drivers and riders won’t know its there until they need it. 

The Crash Reduction Factor for OmniGrip HF ranges from 40% for all casualty crashes, up to 80% for wet weather crashes.  When braking suddenly, a vehicle’s stopping distance is reduced enabling the driver to either avoid the collision or crash at a reduced speed. This could transform what would have been a serious injury crash into one where people walk away.

OmniGrip HF is a vital component of a road manager’s Safe System road safety strategy that aims to eliminate injury on roads.

How it works

Comprised of a thermosetting cross-linking modified compound, the OmniGrip HF system is engineered to hold a high PSV aggregate, such as calcined bauxite, permanently in position so that it doesn’t become embedded or displaced under the heaviest of braking. This ensures consistently high skid resistance and reduced braking distances over the design life of the system.

Upon curing the OmniGrip HF system is resistant to road contaminates including oil, petrol and de-icing salts with excellent adhesion to asphalt and concrete surfaces.
