THE SYSTEM
|
Allan block is a mortarless, stackable, concrete
 block
retaining wall system. The patented interlocking lip
automatically locks each row of blocks in place as they are
stacked. With mortarless construction technique, Allan Block
system requires no grouting, no mortar, and no concrete
footing. The inherent benefits include site adaptability,
installation by general laborers and lower cost.

|
THE DESIGN
|
|
An endless array of design possibilities can be achieved
with Allan Block. A single block shape allows you to build
fluid curves, perfect corners, angles, steps and beautiful
straight walls. Allan Block is available off the shelf in
grey. A rainbow of additional colors is available on
request.

THE
ENGINEERING
|
Built-In Interlock
Allan Block's patented raised front lip and
 hollow core
design provide the best, most flexible connection of any
system on the market. Allan Block accomplishes a built-in
interlock by utilizing :
- The shear strength of the raised front lip at near
2000 pounds per running foot
- Consolidated granular infill in the hollow cores
|
|
Built-In
Drainage
The hollow-core design combines with mortarless
construction to allow water to drain freely from behind
the wall. A vertical "drained field" is formed
by the layer of crushed rock placed behind the rock and
in the block cores. Water moves easily down through the
drained field. The dry-stacked construction technique
allows the water to escape by flowing around the blocks
and out the wall face. This excellent built-in drainage
system prevents any major build-up of hydrostatic
pressure.
|
Hollow-Core System
Allan Block's exclusive hollow-core product design
provides many benefits over solid systems :
- Superior drainage
- Less efflorescence
- Block to block interlock from granular infill
material
- Easier handling
- lighter in weight
- built-in "handles" for
faster installation.
- Faster drying in wet environments
- Lower freight cost
