INFRABLOK® 425
The Infraset InfraBlok® 425 retaining block system is unique in its flexibility and aesthetic appeal.
The block allows for the creation of convex or concave curves.
Transition from vertical concrete filled to plantable inclined installations can easily be achieved.
The blocks interlock in the horizontal plane.
The construction of complex staircases can be incorporated into the wall with relative ease.
Vertical structural walls can be achieved using reinforcing steel to create columns within the wall.
Handrails, light posts and fences can be set in concrete on top and within the block.
The closed-face construction method allows for maximum wall mass and effective backfill compaction.
It is ideal to fill the blocks (in the offset configuration) in order to landscape the completed wall.
Cautionary note
The design of dry-stack concrete retaining systems involves geotechnical rather than structural elements.
Check with your local authorities regarding their requirements for the design, plan submission and stability certification of your retaining structure before starting construction.
