Determine the planned wall s height and width.
Footing for concrete block retaining wall.
To construct a block wall you need to establish a solid footing that is a minimum of twice the width of the concrete block.
Wide footing and extend below the frost line.
If you are building a segmental retaining wall then you will not need a footing.
Concrete blocks are a common building material for a variety of outdoor projects such as retaining walls and out buildings like garages and tool sheds.
Expect to spend 20 36 hours building a 3x10 foot concrete block.
As the last step fill the cores around the rebar with mortar from the bottom to top.
Segmental walls are constructed using individual blocks.
A poured concrete footing for concrete block or brick walls should be at least twice as wide as the planned wall.
The concrete helps stabilize the structure and can prevent sagging or sinking.
The size of the trench and diameter of the rebar depends on the purpose for the wall such.
This should be done at every three blocks or at intervals specified by your local codes.
Block would require a 16 in.
However for even the most modest block structure to have enough rigidity to bear pressure and weight it needs proper footing.
Once you ve got your base set up it just takes some finesse in building the wall up and turning corners.
Because of this the footings will need to be built to create a sturdy base.
For example a typical 8x8x16 in.
The footing dimensions will largely be determined by the size of the wall.
If you plan to use brick cinder block or stone that will include the use of mortar then a concrete footing is recommended.
Whether you re building a retaining wall or just need some extra privacy a cinder block wall is an affordable way to get the job done.
If you are new to this type of project here are a few tools and materials that you may need as well as some steps to help guide you through the process.
Always check local building codes for construction requirements in your area.
The footing should be at least as thick vertically as the wall s planned width.
Footers for block walls consist of a footing trench steel reinforcement rods rebar and concrete.
Insert rebar in the footing when you pour it.
