Our prestressed hollowcore security walls, manufactured by Echo, are not comparable with other walling products. In a class of their own, they protect high-value properties of strategic significance such as airports, military bases, industrial and commercial parks, mines and prisons – in fact any operation that requires over-the-top security.
This is the only precast concrete wall constructed with 50MPa concrete and reinforcing on both sides of the panels. Echo walls are virtually impregnable and cannot be scaled or broken without generating considerable and detectable disturbance.
Speed of construction beats conventional brick or in-situ methods.
Wall panels can be dismantled and reused because they are not grouted but assembled with tongue-and-groove shear key joints instead.
