conception of GeoStone Retaining Wall Systems was preceded by a
construction company owned and operated in Birmingham, Alabama by Fred
Agee which since 1989 has specialized in the promotion, design, and
construction of segmental retaining walls.Mr.
Agee built the first segmental retaining walls in the state of Alabamaand since
then has used most of the segmental wall modules available on the
market.Each module has its
unique patented design for achieving connection strength.
experienced first hand the limitations and restrictions to wall
construction imposed by the wall modules on the market, Fred Agee
created the design of the GeoStone product as we know it today.
first step in the manufacturing process is the design and building of
the GeoStone molds compatible with the machines used to manufacture
block in a concrete block plant.
The next step involves extensive testing of the module to determine the
connection strength which is used to develop the design criteria used by
engineers in the designing of GeoStone Retaining Walls.
NCMA Segmental Retaining Wall design software as a convenience to
engineers in the design of GeoStone Retaining Walls.
achieved successful results from the connection
strength testing and experienced excellent results from the
manufacturing and marketing of the product, efforts were undertaken to
achieve copyrights and patents for our moduleís unique design.
the patents have been obtained and close to one million GeoStone modules
have been used in construction of retaining walls in North America.There
are plants in
Alabama, Arkansas, Georgia,
Mississippi, Tennessee, and Virginia who are
currently manufacturing and marketing GeoStone under our license
