The system uses the Asset VRS Zoneguard Vehicle Restraint System as its core, with modular elements added to meet the demands of both urban and non-urban applications; these elements include anti-climb fencing, pedestrian portals, vehicular access gates, connections and transitions to the National Barrier Asset (NBA) systems, end and intermediate terminals and special units to allow for differences in both horizontal and vertical alignment.
Its unique shape, with its large footprint, has been specifically designed to block vehicles. Each 430kg, 1m × 1m × 1m solid rubber unit is connected by steel securing cables, providing the flexibility to protect both entrance areas and site perimeters against hostile vehicle attack. With the units in position, the steel securing cables can be anchored to create a stronger physical barrier.
Requiring no foundations, the surface mounted system can be rapidly deployed as a temporary or permanent security measure, as part of a robust hostile vehicle mitigation (HVM) strategy.
The Impakt Defender has been successfully impact tested to IWA 14-1 specification, stopping a 7.2 tonne N2A lorry travelling at 48kph (30mph).
Used across the globe for over a decade, the innovative design of the panels enables them to be quickly and securely installed on any surface, including concrete, asphalt, gravel and grass. Their robust construction enables them to be installed almost anywhere, removed and used again and again.
These panels have an expected lifespan 25 years+ under typical service conditions and subject to correct installation. No maintenance is required, however, regular installation inspections should check that all panels are correctly positioned and supported including ensuring all fixings are in place.
