The Alfabloc system is a very structurally
effcient and versatile concept in design. In
the majority of working conditions the Alfabloc
units are lowly stressed and provide a robust
retaining structure. With granular materials,
which generally provide the most onerous
loadings, the Alfabloc unit has additional
stability generated by the frictional force down
the face of the wall.
Experience has shown the units can
withstand signifcant abuse by loading
machinery used to move the retained material.
However, as with any relatively thin walled
concrete structure, they will suffer damage
with persistent and negligent abuse.
The foundation for the Alfabloc system is
usually the new or existing concrete slab onto
which stored materials will be contained. The
loads imposed by the Alfabloc units are usually
no more than the wheel loads imposed by the
loading machinery utilized to move the stored
material. Depending on the nature of the stored
material, the units can be either simply placed
onto the concrete slab or bolted into place. To
assist in the spread of load horizontally, the units
are nominally fxed together with a galvanized
plate, which also provides a seal to the joints.
