What would be the best waterproofing product to use on a cmu retaining wall?

UGL Drylok comes in both water base and oil base, can be tinted as well, higher v.o.c with the oil base product, so if anyone has respiratory issues , best to use PPE Zinsser’s watertite mold mildew waterproofing works well up to 20psi hydrostatic pressure, ultra low odor latex, 15 yr h2o proof/10yr mold / mildew

My personal opinion is Sika 701W. This is a very good product that I’ve used many times in the past but you do have to be careful if it’s around any metal or glass since it does tend to stain. All in all it’s a good, breathable sealant.

By far my favorite product to use these days is Bluemax made by “Ames”. It’s made of a special blend of high strength elastic liquid rubber. It dries to a tough 800% elastic membrane that resists cracking and peeling. It can be applied by a spraying machine or a trowel.
