How are HAENER Block Structures made?
How does the strength of a Haener Block compare to that of a conventional
The Engineering Research and Testing Report of the NCMA results show that
the Haener Block wall is almost 10 times stronger in shear than allowables
required for conventional block by the Codes.
In what sizes can Haener Block be manufactured?
The Haener Block can be manufactured in almost any combination of basic
How are Doors, Windows and Columns Made?
By using only the blocks incorporated in the System, Haener Block can be
used to construct windows, lintels on doors, and columns.
Must Haener Block be Solid Grouted?
Haener Block is the same as conventional block- local building codes
must be referenced. If hollow conventional block is allowable, Haener Block
need not be grouted solid.
Can Haener Block work with a non-solid grouted structure?
Yes. In a mortarless block wall which is not solid grouted, the joints have
to be sealed by caulking or use of a sealant which can be sprayed or painted
on the surface of the blocks. Many methods and products are on the market
for this purpose. The conventional method of plastering can also be applied.
What about Insulation?
Haener insulation blocks can be made in an 8" width, with insulation
inserted into the cavities of the wall. With smaller widths, we advise that
insulation be placed outside the wall which is then plastered.
An alternate method of achieving insulation is using two walls with a four
inch air space between them.
How easy is it to build without prior experience?
Haener Block has been used extensively for years in California by do-it-yourself
home and apartment owners with no prior masonry experience for everything
from a barbecue to a room addition. In Mexico and Turkey, unskilled workers
constructed their own houses.
At Folsom Prison in California, unskilled prison labor was used to construct
well aligned, aesthetically pleasing fences and structures. In Arizona,
a gaming casino was constructed using only one skilled mason. All other
workers were unskilled local labor.
Approval of Building Codes
The uniform building
codes were referenced at all stages of the design and tests were performed by the
National Concrete Masonry Association Research and Development Laboratories
in Chagrin Falls Ohio.
