Remediation of gravel foundation base damaged by water main break

Remediation of gravel foundation base damaged by water main break

Remediation of gravel foundation base damaged by water main break

(OP)
Hi all,

I have a commercial building in the Yukon where a large water main break has probably disturbed the gravel base under/around the foundation. The building is a conventionally framed shop and from the drawings it looks like it has shallow thickened edge footings set on a deep gravel base. From laser level readings and interior damage it looks like the building has not moved significantly but that could change as the weather warms.

I have recommended a local geotech but I'm wondering what remediation might look like. For the most part I expect the gravel to be self-compacting and perhaps some type of sounding or injection would typically be used to locate and fill any large voids. I can see where void filling could be counterproductive though.

TIA

Micropile with a foundation attachment bracket. Another option would be chemical grouting.
The third, and most economic (at least in the short term) is to monitor the building and see if it moves.
Why fix what isn't broken? Most owners will opt for this since it is cheap, and confirms there is a problem
before spending thousands on a fix.

Now fellas, how do we come up with solutions to what we don't even know is a problem? Preliminary report shows nothing particularly bad. Wait for the geotech. As a geotech with what I see so far I'd do detailed observations of the structure. Water main breaks are common in my area and any damage, if any, usually shows up then.
