Most of my footing is exposed in the basement. The slab begins about 2” above the bottom. I get water up from the floor and between the footing and foundation wall which runs down onto the floor. Downspouts on this side of the house Run out to the road. Outside is a driveway pitched away from the house.
I was thinking of using this product to direct water running down the wall and coming up into a sump pump. I can’t do a traditional french drain inside as it would involve digging below and next to the footing. The water guard solves that.

Doing this means their will be a gap between the footing and slab. Is this safe or is the slab necessary to keep the footing in place.

Drain tile below the floor would be much better way to go, usually the floor is on top the footing, when you put a drain inside you are usually looking a sump pump to get the water out.
Any signs of water thru the wall?

You cannot dig a trench all along the footing deeper than the foundation footing bottom otherwise the foundation could shift.

A drain tile on the outside may be a suitable way to go. It can go to a sump pump pit outside or cross through or, yes, under, the foundation footing to a sump pump pit inside. Not up and over. To cross under, dig a crosswise trench just big enough to run a pipe through and retamp dirt or sand around the pipe under the footing quickly.

Also do not have water land on any exposed part of the footing extending past the outside of the building outside and stay there.

that extrusion is made to sit on top of the foundation & still have the original floor in place,,, its basement system's invention & many of their franchisees use it,,, obviously there are copies avail on the market,,, what's not appealing to be is the replaced conc will only be 2" thick whereas original floor was probably 4" thick for a reason - its MUCH stronger than 2",,, personally i'd opt for the pipe alongside the foundation - more work, yes,,, stronger ? of course, but we do this work for a living
we're not fans of bringing exterior water inside - defeats the purpose of a sub-floor leak management system
