paint on and spray on water proofings. even xyprex additive. when repairing leaks and cracks. 90% is all about prep work. if you goof up on prep, then you can except to have bubbling of paint and spray on water proofers. and/or cracking of all types which cause more leaks.
each product can be different than in another in what type of prep work you need to do, and what you should not do. even though you might think it would help could cause problems for a given water proofer product out there.
i honestly never have kept track of all the different types of "water proofing" stuff out there. just way to many, and majority of what i have seen over the years has been due to improper prep work, either not enough or to much prep work.
============
with above said. folks go crazy over different products and cost when installing ponds. (
Koiphen.com) sani-tred, to lots of other products have been tried. and opinions of products can be good to bad. pending on who you ask. (again prep work) and what they are wanting to do with it.
for example ((pre-existing basement that is leaking)). if you have basement walls. and in middle of the wall water is coming in. a french drain might do some good. but you may want to look more at dealing with surface water on outside of the house. ((redo gutters and were they drain to. and install pipe work for gutters, and perhaps re-landscaping and grading the yards outside the house))
if you are getting water around bottom of the walls of the basement. french drain more likely work much better. there are so called ""de watering"" setups that look kinda like trim that you glue / silicon on around bottom corner edge of all the outside basement walls. and it kinda works like french drain. then there is a complete french drain setup, were they come in with concrete saw, and cut a path around entire basement a couple feet from wall ((so they do not hit footers for walls)) dig out dirt, and concrete chunks, put in gravel and holed/sloted drainage pipe. and run to sump pump or lower part of yard.
for example ((building a basement / house right now)) folks will tend to use tar, or epdm liners for like ponds, to epdm like liners for flat roofs and wrap entire basement in. to other products and install a french drain down near the foots of the basement walls. some folks if cash allows were coat outside of basement walls with a stuco or thin layer of concrete with xyprex mix. to also obtain a water proof outside doing on walls. while others might use a spray on or paint on water proofer.
for example((already existing basement and house and having leaks)) when folks put on paint on and/or spray on water proofer to the """inside of the walls""" of a basement. folks can easily get bubbling of the paint. due to force of water simply pushing the paint right on out and away from the wall. and in order to keep your water proofing stuff held on and not bubble or crack. it also depends as much on your water proofing product, but also if you have concrete block, or poured concrete walls, or other type of basement walls. some of it may require you take a metal grinding wheel, other products may state mutric acid wash, others might state everything fully dry. double check regardless of what ever product you end up going with. with the manufacture for the best "adhesion" so there less likely a failure of a given product from happening.
