Retaining/MagnumStone walls
Retaining SolutionsMagnumStone hollow core block walls for civil and commercial projects
MagnumStone is a large-format hollow core interlocking concrete block system Fencepac installs for fast, cost-effective retaining on major civil and commercial projects — 0.74m² of face area per block and 40% less concrete than solid block alternatives.
Large hollow core blocks when the wall has to go up quickly
MagnumStone is a large-format hollow core interlocking concrete block system designed for fast, cost-effective installation on major civil and commercial projects. Each block covers 0.74m² of face area and uses 40% less concrete than solid block alternatives — reducing material costs and transport weight without sacrificing structural performance.
Walls can be designed as gravity or geogrid-reinforced, with a LedgerStone natural rock face finish. The system suits heavy surcharge and bridge loads, with a positive geogrid connection for high safety factors and faster installation with minimal manual labour.
Fencepac designs MagnumStone walls to AS4678 and constructs them with our own crews. It sits in the same retaining offering as crib, segmental, gabion, and MSE — selected when the height, load, and program fit a large-format hollow core block.

When MagnumStone is specified
MagnumStone systems we install
Gravity or geogrid-reinforced MagnumStone, specified to surcharge and finish.
Large Hollow Core Blocks
Each block covers 0.74m² of face area and uses 40% less concrete than solid block alternatives.
Gravity MagnumStone Walls
Gravity design where the hollow core mass and geometry are enough for the height and load.
Geogrid-Reinforced MagnumStone
Positive geogrid connection for high safety factors on taller walls and heavier surcharge.
LedgerStone Face
LedgerStone natural rock face finish where the wall has to read as stone rather than a raw block.
Heavy Surcharge & Bridge Loads
Specified for sites that need to carry heavy surcharge and bridge loads.
Faster Installation
Large-format blocks designed for faster installation with minimal manual labour.
Frequently asked questions — MagnumStone walls
MagnumStone is a large-format hollow core interlocking concrete block system. Each block covers 0.74m² of face area and uses 40% less concrete than solid block alternatives. Fencepac designs and constructs MagnumStone walls as gravity or geogrid-reinforced systems.
MagnumStone is typically considered on major civil and commercial projects where a large-format hollow core block reduces concrete, transport weight, and installation labour. Segmental masonry is often used where a smaller modular face or a specific masonry product is specified. We help choose based on height, loads, program, and finish.
Yes. MagnumStone can be designed as a gravity wall or with geogrid reinforcement and a positive geogrid connection for high safety factors.
MagnumStone is available with a LedgerStone natural rock face finish.
