GRIPBlock Walls are Bulletproof!

Описание к видео GRIPBlock Walls are Bulletproof!

GRIPBlock walls are not just strong, sturdy and fireproof – they're bulletproof too! When filled with just dirt and gravel, this GRIPBlock wall withstood over 100 rounds of 5.56 NATO rounds fired from close range. Not a single shell exiting the other side of the wall. The applications for military and defence are immense. Watch the video to see the proof.
