One of the most common and telling failures of retaining walls is the inevitable tilting cracking and bowing of brick timber and concrete block retaining walls built by homeowners well meaning builders and landscapers.
Pouring concrete walls before and after.
Available from diy stores and ready mix concrete companies these contain soluble emulsions that form a protective film when sprayed directly onto the surface of newly poured concrete slabs or walls.
After the wall is sized each wall member is checked for adequate strength and steel reinforcing is determined.
The process involves building a form to hold the concrete in place installing reinforcing rods and then pouring the concrete.
To do this you ll need to drive stakes into the ground where you dug the footings.
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.
Poured concrete foundations are an alternative to block or treated wood foundations.
One reason this is comparatively safe is that footings are frequently sized to meet local code minimums that are actually oversize when compared with the load that the wall will place on the footing.
