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.
Before you can start pouring the retaining wall you ll need to build the forms.
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.
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.
Once cured the concrete provides a secure and stable foundation for the home that will be built above.
To do this you ll need to drive stakes into the ground where you dug the footings.
The process involves building a form to hold the concrete in place installing reinforcing rods and then pouring the concrete.
Poured concrete foundations are an alternative to block or treated wood foundations.
