Wide footing cantilever retaining walls may be built using in situ reinforced concrete or precast masonry blocks.
Concrete rubble retaining wall.
Rubble walls provide a unrivaled natural and classic look that is hard to achieve with other wall systems.
The lateral forces from backfill is resisted by the weight of wall itself and due to their massive nature they develop little or no tension.
Therefore they are usually not reinforced with steel.
They are built from solid concrete or rock rubble mortared together.
The wall acts as one mass to resist the thrust from the backing and is much more stronger than dry stone masonry wall.
See reference 1 pages 13 to 14 in each area you wish to build a section of wall dig and level a space as wide and deep as you wish to plant.
For extra stability put down a layer of gravel or.
Rubble walls are effective retaining wall systems but become more and more costly as the height of the wall increases.
The base of a rubble wall is usually around 1 2 of the height of the wall.
Brick masonry stone masonry or plain concrete retaining walls.
Gravity walls can be built out of various materials including concrete stone rubble granite rubble gabion baskets or modular block.
Gravity walls are typically wider at the bottom and taper down as we work to the top of the wall.
Gravity walls are the earliest known retaining structures.
These walls are also provided to support earth loose stone coal etc.
Embedded footing cantilever walls may be built from round or square h5 treated timber or precast concrete poles or i beams.
The stability of the wall depends entirely upon its dead weight.
