Wall systems
The ground decides first, then the height, then the finish. We recommend the wall the site calls for, then design it, supply it, build it and certify it.
Crib block retaining walls
The system the company is named after.
Keystone retaining walls
Keystone is the segmental block system behind many of our largest subdivision and commercial walls.
Allan Block retaining walls
Allan Block is a mortarless, hollow-core segmental system with a raised rear lip that sets the batter and locks each course.
Keymass retaining walls
Keymass is a large-format precast block system placed by excavator.
Concrete sleeper retaining walls
Reinforced concrete sleepers slotted between galvanised steel posts set in concrete.
Gabion walls and scour protection
Gabions are wire-mesh baskets filled with rock, stacked to form flexible gravity walls, and laid flat as mattresses to armour banks and channels.
RSS precast concrete retaining walls
Our RSS precast walls use factory-made concrete components engineered for applications where the ground moves.
Segmental block retaining walls
A segmental retaining wall is built from individual concrete blocks, dry-stacked with no mortar, that lean into the bank at a set batter.

- Crib block
Gravity wall that tolerates ground movement, follows curves and can be planted. Single course to multi-tier.
- Keystone
Pinned segmental block with geogrid for engineered heights and a finished masonry face.
- Allan Block
Hollow-core segmental block with drainage built into the face. Strong on curves, steps and corners.
- Keymass
Large precast blocks placed by excavator. Height, speed and mass for civil and industrial sites.
- Concrete sleeper
Sleepers between galvanised posts. Fast and vertical, suited to long low runs and boundaries.
- Gabions
Rock-filled baskets that flex instead of crack. The choice for creeks, channels and scour.
- RSS precast
Factory-made precast components engineered for ground that moves, with a consistent face.
- Core-filled block
Reinforced masonry cantilever for vertical walls that carry slabs or buildings, with no room for a batter.
- Stacked rock
Machine-placed boulders for a natural finish on batters, creek lines and landscape work.
