LAVA-Volcanic Architecture

No.  LAVA concretes are not as subject to shrink-cracking as are regular concretes because LAVA concretes are placed relatively dry.  Shrinking while drying/curing is the cause of most regular concrete cracks.  Cement block tends to develop stagger cracks along the masonry joints.  LAVA has no masonry joints.  Poor soil preparation can cause  foundation cracks in any material.  LAVA concrete is more resistant to all these types of failure than regular concrete.
