Design considerations gravity retaining walls will vary in height depending on the application.
Concrete rubble retaining wall.
Gravity walls are the earliest known retaining structures.
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.
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.
Gravity walls can be built out of various materials including concrete stone rubble granite rubble gabion baskets or modular block.
These walls are also provided to support earth loose stone coal etc.
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.
The base of a rubble wall is usually around 1 2 of the height of the wall.
Therefore they are usually not reinforced with steel.
Poles are typically spaced between 900 and 1 800 mm and set in concrete see figure 5.
For extra stability put down a layer of gravel or.
Rubble walls provide a unrivaled natural and classic look that is hard to achieve with other wall systems.
Wide footing cantilever retaining walls may be built using in situ reinforced concrete or precast masonry blocks.
They are built from solid concrete or rock rubble mortared together.
Brick masonry stone masonry or plain concrete retaining walls.
Rubble walls are effective retaining wall systems but become more and more costly as the height of the wall increases.
