Flowable Fill, Geofoam to Reduce Pressure on Foundation?
Flowable Fill, Geofoam to Reduce Pressure on Foundation?
(OP)
I'm looking for specifications, recommendations on reducing soil pressure against a poured foundation wall with inadequate reinforcing to support backfill to it's 10 ft height. What are the specifications(weight) for flowable fill and does it need to be poured as a seperate wall from the foundation or can it be used as backfill?
Thanks,

here is a typical specification

please note that it is not a lightweight material at 90 to 125 lb/ft^3

To expand on BigH's point, elastizell is avalable in a range of densities. Obviously, lighter may be more expensive and have less strength. As with other flowable fills, it does become self-supporting after it sets up.

We were thinking of erecting a form for the flowable fill away from the foundation and filling in between with something to keep soil pressure off the wall. We need about 25-28 pcf or less to make the wall work. Elastizell sounds interesting, does anyone know how the costs work out versus Geofoam?
