Surcharges
Setback
   

Under certain conditions, the block weight and setback alone do not provide enough structural support.
   

Curves & Serpentines
Curves accent any landscape, are simple to design and easy to build. Consider how tight or gentle you want the curves to be and choose the block or combination of blocks that are best suited for your design.

Setback
   

Under certain conditions, the block weight and setback alone do not provide enough structural support.
Allan Block Reinforcement Grid provides a simple solution by creating a solid structure with more resistance to soil pressure and surcharges.
   

Curves & Serpentines
Whether you chose soft curved walls or classic straight walls, Allan Block has the system to satisfy every design.
Curves accent any landscape, are simple to design and easy to build. Consider how tight or gentle you want the curves to be and choose the block or combination of blocks that are best suited for your design.
