Footing partially in a water table, what precautions
Footing partially in a water table, what precautions
(OP)
I have never considered this one before
Time to consider now, a footing supporting a light framed building, where bearing capacity is no big deal, but geotech reports a water table very close to the surface. I am not involved in the design but I would like to know if there are simpler solutions to the problem

Yes it did occur to me that water must be removed and filling must be made. However I am not familiar with this kind of practice.
A friend suggested I put a geotex at base level all over and cover it with a thin lean concrete layer stuffed with mesh to prevent water flow upwards and the mesh to protect the geotx.

One other consideration is dilution of the concrete. If you place concrete into a water laden footing, you will dilute the concrete, since there is likely an inadequate volume to displace the water as is done in shaft placement. Make sure the concrete is not diluted as this occurs mostly at the bottom where the concrete needs to have both good strength and good durability (protection for the rebar).
