The spacing between the stakes will depend on how thick your retaining wall will be and the thickness of the wooden planks used as the forms.
How thick are concrete retaining walls.
The footing dimensions will largely be determined by the size of the wall.
Many variables affect that cost including the design the wall s location on your property and how much concrete contractors in your area charge.
For example if you are pouring a retaining wall that will be 12 inches thick and will use wooden planks that are 1 1 2 inches thick for your forms you ll need to space the stakes about 15 inches apart.
Poured concrete foundation walls that are less than 8 feet tall and have soil outside that is 6 or 7 feet deep against the wall can often be 8 inches thick and function quite well.
To create a solid foundation dig a trench for the first course of your interlocking retaining wall blocks to sit in and make sure the ground remains even throughout.
The footing should be at least as thick vertically as the wall s planned width.
The thicker the wall is at its base the better.
For cantilever and counterfort walls the stem thickness at the base is often about 10 of the total wall height as is the base slab thickness.
As soon as you go higher or have greater depths of soil pushing against the wall you need to increase the thickness to 10 inches.
If you add a decorative finish curves steps lighting or other upgrades the cost will rise.
The appropriate depth of the wall depends on several factors and there is no single standard for every home.
A poured concrete footing for concrete block or brick walls should be at least twice as wide as the planned wall.
For a basic wall you can expect to pay between 30 and 60 per square foot.
The wall can get thinner as the wall gains height.
Determine the planned wall s height and width.
Mass or thickness is your friend in almost all cases when designing and building a retaining wall.
Concrete foundation walls support the home standing above so any weakness can undermine the stability of the house.
These consists of a concrete or masonry wall of uniform thickness vertical wall reinforcing and transverse footing reinforcing are all designed for the lateral shear and cantilever bending movement plus the vertical weights of the wall footing and earth fills.
Nationally the cost to install a concrete retaining wall ranges from 2 000 to 15 000 but the average cost is 3 500.
The success of your retaining wall depends on a level base.
The total cost to have a concrete retaining wall installed will be a combination of material and labor prices.
The thickness or depth of concrete basement walls plays an integral role in their long term strength and durability.
Using a tape measure decide the length and the width of your retaining wall then mark off the area with the garden stakes and string.
