2- Unskilled Labor
A single mason can quickly train and supervise a group of unskilled
workers to build with the Haener Block System.

3- Ease of Use
The blocks are dry stacked, self-aligning, and interlocking, and can be used for both interior and exterior walls.

4- Universal Acceptance
Unlike many low cost building materials, concrete block is utilized and accepted around the world for its superior strength and aesthetics.

8- Can Be Insulated
There are multiple options for insulation with Haener Block - from Haener Block insulation inserts to panels or foam.
