Haener Mortarless Block

The Haener Interlocking Block system provides substantial reductions in the cost of installing concrete block walls though significant savings in labor and material. Three units are the basis of the Haener system: Stretcher Block, Half Block, and Corner Block. The self aligning lugs molded into the unit permit each course of block to be locked together without the need of mortar. Beveled edges give the appearance of tooled joints.
