It’s no surprise that a wall made of 6”steel reinforced concrete columns is stronger than one made of wood. The impressive feature is just how much stronger.

Dynamic shear tests, designed to simulate earthquakes, measured RASTRA’s strength to be up to 700% stronger than traditional wood frame walls. In fact, tests elevated to simulate a magnitude 8.5 level earthquake on a 6 story structure, caused no structural damage.

RASTRA walls are engineered to stand up to the challenges of severe climates including tornados, fires, hurricanes even earthquakes.


Strength where you need it.

RASTRA® is the most rigorously tested ICF!
