My basement concrete floor starts leaking at the beginning of Spring since last year (2020).It’s only the centre part fo the basement where the column post meets the floor. I noticed there’s a gap between the column footing and the floor.It looks like the water seeping its way through this gap (red line in the picture) that joins between the post footing and the concrete floor.
Is this something that can be fixed by just applying some kind of waterproofing sealant along that red line (gap/ join line) or this is more than that?
BTW, the leaking will stop in less than 2 weeks. It happens only at the beginning of spring, when the snow starts melting.
