    WELCOME TO ALLAN BLOCK
    Allan Block's built-in features make retaining walls easy to engineer and simple to build. These simple engineering features make Allan Block retaining wall systems the most efficient and reliable products on the market.

    With over 16 million square feet of Allan Block installed throughout North America, we can provide the experience and support to make your next wall a success.

    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 labours 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 onthe 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

    TYPICAL SECTIONS
     AB GRAVITY WALL
    A Retaining Wall that Relies Solely on its Own Weight for Stability.

     AB GEOGRID WALL
    On Higher Walls When the Soil Pressures exceed the Stability Forces provided by the Self-Weight of the Wall, Horizontal Layers of Geogrid or other Geosynthetic Materials are used as reinforcement.
