Mitigate the Impact of Explosions

By absorbing and redirecting the force of the explosion, these barriers help prevent damage to structures and equipment, reduce the risk of injury to personnel, and limit the potential for collateral damage. This aspect is particularly crucial for high-risk areas such as military bases, industrial facilities, and crowded public events.

Defend Against Vehicle Crashes

K-ratings play a pivotal role in indicating the level of protection a barrier offers against vehicular impact. The K-rating system, recognized globally, provides a standardized way to quantify a barrier's ability to withstand specific vehicular impact speeds and weights, thus highlighting its security strength.

The K-ratings recognized by the Department of Defense (DOD) are as follows:Vehicle Crash K Ratings

These ratings are assigned based on the speed and weight of the impacting vehicle, with higher ratings indicating a barrier's increased ability to thwart potentially devastating vehicle-borne attacks. Kontek's Modular Blast Barrier is rated at K12+ with the ability to withstand a 20,000-lb. vehicle traveling at 50 mph.


The K12+ rating of the Modular Blast Barrier underscores its exceptional strength and resilience, showcasing its capability to repel formidable forces and safeguard against a wide range of vehicular threats. In the spectrum of K-ratings, K12 represents barriers that provide the highest level of protection, signifying its proficiency in countering even determined vehicular assault attempts.
