    Hi,

    I got my foundations dug today and concrete being poured tomorrow morning. I noticed about 40mm of water in some parts of the trenches but not all over. Is this a problem?

    Thanks

    The simple answer is you need to get your Engineer to confirm that concrete is going onto firm ground. This needs to be done irrespective of whether water is now in foundations or not. Presuming trenches were dug down to firm ground you may need to dig out soil that has been softened by water. If ground soil has not been softened then concrete should push water along foundations and it can be removed at end of pour - usually with buckets.
    I am not an Engineer and it is your Engineer who should advise based on situation on ground.

    as posted above, there should be no sitting water in the foundation trenches, dig a sump at the lowest part of the trench and pump (or bucket) the water out before the concrete arrives.

    I'd agree with the excellent advice above.

    Get your Certifier (Engineer / Architect / Arch. Tech.) out on site to inspect trenches prior to pour.
