These innovative, affordable wooden bricks are light and durable, so they can be delivered and assembled quickly. Unlike most temporary structures, GRIPBlock walls block the wind and retain warmth, helping bars and restaurants stay open – and in business – longer, and well into the winter season. And while the walls are structurally sound, with shear strength that makes them impossible to knock over, at the end of the season they’ll be easy to disassemble and take down.
