Rubble walls are effective retaining wall systems but become more and more costly as the height of the wall increases.
Concrete rubble retaining wall.
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 are the earliest known retaining structures.
The base of a rubble wall is usually around 1 2 of the height of the wall.
For extra stability put down a layer of gravel or.
Design considerations gravity retaining walls will vary in height depending on the application.
Therefore they are usually not reinforced with steel.
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.
They are built from solid concrete or rock rubble mortared together.
Rubble walls provide a unrivaled natural and classic look that is hard to achieve with other wall systems.
Gravity walls are typically wider at the bottom and taper down as we work to the top of the wall.
Poles are typically spaced between 900 and 1 800 mm and set in concrete see figure 5.
Gravity walls can be built out of various materials including concrete stone rubble granite rubble gabion baskets or modular block.
Brick masonry stone masonry or plain concrete retaining walls.
Rubble walls typically have a concrete footing and the footing width is 6 12 wider than the base of the wall.
The stability of the wall depends entirely upon its dead weight.
