Having exterior waterproofing done. Couple basic questions.
yes have a footer drain. Pipe it out from the drain around the foundation to a water holding tank with a submersible pump and pump that water out safely to another location. More on reddit.com

Waterproofing recommendations for exterior patio
Best option is a sleepers + decking over a membrane (EPDM, TPO, etc.). I’ve done a lot of TPO membrane the last 10 or so years and like the product - but it’s a little more expensive than EPDM. More on reddit.com

r/homeowners on Reddit: Exterior foundation waterproofing? Has anyone done it themselves? What products did you use what difficulties did you encounter
August 2, 2019 -

My house is about 100 years old, farmhouse with a poured concrete foundation.

There are a few grading issues, a few downspout issues, and because of coldjoints in the poured foundation a few spots that leak water when the ground is saturated.

The house is set into a slope so from the uphill to downhill side the foundation walls are only 3-4' below finished grade.

There is an exterior weeping tile as the downspouts are tied into it (that is a item to be fixed asap) but given its age who knows how well it is performing.

My thought process was, figure out what product would work best, dig out one wall at a time, apply coating, membrane, new weeping tile, tile the tiles into a french drain that will drain out into the yard downslope of the house.

Then as i complete each wall i can backfill and re-grade correctly to prevent any future water intrusions through the wall.

My skillset - residential construction mostly interior finishing, and arborist, so im not afraid of hard work, just this is an area outside of my knowledge base so i'm hoping to learn and be able to do it myself.
