What basic materials are involved
in producing concrete blocks?
Washed Sand 3/8" Aggregate, Portland Cement, Water, Chemical
Admixtures. Goto Top
How are these materials mixed
and formed into concrete blocks?
A specific mix design is entered into the batching computer. The
computer will then weigh up the prescribed amount of each ingredient.
The ingredients are then put into a stationary mixer located in
the block plant. As the ingredients are mixed, the computer makes
sure the mix isn't too wet or dry and adjusts accordingly. Once
the mix is ready, it is dumped from the mixer into a hopper on
the block machine. The block machine takes the right amount of
mix, places it into the mold, vibrates and compacts, the mix to
the appropriate height and hardness for the block. Goto

How are the newly formed concrete
blocks cured?
The newly formed concrete blocks are placed in a kiln. The kiln
is heated by steam and that causes an acceleration of the hydration
process, which is the evaporation of the water in the block. This
heat allows the concrete blocks to attain a much greater strength
at a shorter period of time. Goto Top
What happens next?
After about a 24 hour period in the kilns, the concrete blocks
are stacked on pallets and placed in the yard. These blocks will
then wait to be delivered by truck to the jobsite. Goto

What is important about fully-cured
concrete blocks?:
More than meets the eye. Concrete blocks are fully cured at the
factory, baking out the moisture so that foundations built with
concrete block are more stable and much less likely to shrink
and
crack than other foundations once it is laid. Goto

What makes concrete walls better?:
They are built by skilled craftsmen, one block at a time. And
the blocks themselves are designed to ensure flexibility and waterproofing
advantages. Plus, they help save energy, reduce gas infiltration,
provide quieter walls and stability to your home. Concrete block
also lends itself to a wide variety of insulating options for
the exterior and interior walls or inside the hollow cores. Goto

Why Concrete Block?:
It’s Proven: Concrete block basements have been
the choice of fine homebuilders for more than 90 years.
It’s Strong: Yep, it’s concrete block. And
concrete block walls are not only strong, by are also built wider
to be more resistant to ground movements and soil pressures.
It’s True: Hand-built by skilled craftsmen, concrete
block walls are straight, plumb and level. Carpenters appreciate
the superior foundations that concrete block provides –
plus you save time and money because they won’t have to
level and shim each wall.
It’s Dry: A truly important feature. Concrete block
walls provide a natural barrier to moisture. The hollow cores
prevent walls from sweating in summer and frost from building
up in winter.
It’s Safe: Made of 100 percent noncombustible materials,
the fire-resistant blocks help keep you and your family safe.

Will my basement leak?:
It’s less likely if you use a concrete block foundation.
Concrete blocks have a specially designed hollow core that acts
as a natural drainage system, minimizing the possibility of leaking.
Other foundations are not designed this way. You should ask your
builder to place a high-quality, waterproof coating over the exterior
side of the walls, as well as set up a proper drainage system
around the basement. Goto Top
