Omni Block's insulated masonry system is structurally stronger than stucco over foam over woodframe which has been the most widely used building method in Arizona. However, the number one complaint received at the Registrar of Contractor's Office is stucco cracking and the lack of proper and timely contractor repair. The surface bond is water resistant and totally seals the wall system. It can act as either the 'brown' or the finish coat depending upon the desired finish. The older the block system gets the stronger it becomes.
Cracks are therefore extremely rare.
Several manufacturer's of this material are available and almost all offer a twenty year warranty. This is an optional finish to the Omni Block surface bond system, however. This has significant advantages in apartment buildings, condominiums, commercial and institutional applications, as well as, residences.
