Wall systems
Ten systems, one contractor. The ground decides first, then the height, then the finish. We recommend the wall the site calls for and design, supply, build 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.
