The "footprint" approach is a good idea anyway if you're putting the tent up on anything other than a putting green as it's sacrificial protection for an expensive tent. I've usually cut mine to be about an inch or so smaller all round than the tent groundsheet - lay it on the ground, put the tent up on top and go round with a stanley knife. Ideally it would be a bit bigger so you could lift up the edges to form a kind of tub but in practice I've found that some bit usually drops down and forms a kind of funnel to channel water in.

That pretty much exactly describes my predicament both in terms of the material, symptom of water entering and the likely mistake I made with footprint dimensions, whose existance, it took this one night to highlight!
So, a new footprint is in order (mine is looking pretty tatty and has been üpnctured here and there by twigs, stones and what-not). Shame to hear there is no cure for the porous ground sheet condition, but good to know this could be mitigated with a decent footprint shape.
