Flood Related Foundation Scouring
Flood Related Foundation Scouring
(OP)
Got a question...
Assuming that the foundation for a resiidential structure is still intact, are there any other easier or less costly methods other than pin pile and/or CDF to replace the material scoured from under the foundation?
With the flooding we had here in Dec/Jan, there are a lot of residences in numerous floodplains that have this problem.
Many of the areas that were initially scoured were later filled in to include areas under the foundation and will have to have this material removed and replaced/repaired some way.

The walls were off plumb and the school was still using the structure in an earthquake zone( Some people do not think at all ) We took on the project and drilled and pressure grouted under the slab foundation.It all came back up nicely into place. We were not sure it would come back up properly. It was a case of try it and see what happened or demolish the building.
You could do it under other types of foundations but you may need to contain the grout by solidifying the ground around the structure or several ft below in the case of soft ground and then pressure grouting. Not easy, not cheap

One advantage to FF is cost. If you explore this option, you might consider making sure that the flowable fill is placed to maintain a few inches of head over the bottom of the foundation.
The Canadians have done quite a bit of research on flowable fill and you might check with the Canadian Institute for Research in Construction.
What do your local Geotechs say about the better alternatives?
