sure void footer
sure void footer
(OP)
I am currently having a new house built and have a question concerning the footer. The builder has just finished pouring the footer and is preparing to pour the foundation (basement) walls. I am very picky and question things I don't agree with. Anyhow, they have used a sure void with a lite skim coat of concrete for the footer. So I am wondering if it is possible that they poured another concrete footer beneath this that I am unable to see or is this it? I understand the reason for a form void but we are talking about 8" thick 9' tall foundation wall setting on this, not to mention the 2 stories of house above that. Can anyone give me some peace of mind?





RE: sure void footer
Does the house have drilled piers beneath the walls? If so, they are supporting the structural loads, and the walls are designed to span between the piers -
I am confused by your statement, they have used a sure void with a lite skim coat of concrete for the footer - please explain.

As a side note - the design and construction of the house may be sound. But void forms beneath walls - in a sand environment - sounds peculiar.

RE: sure void footer
The soils report most likely has given a footing recommendation with a maximum bearing capacity and a minimum dead load requirement, due to some moderately expansive clays in the soil.
Typically the void form is installed below the footing to allow the minimum dead load requirements to be met.
