Unfortunately one of the disadvantages of this Penetrating Clear concrete sealers is that like many others, they don't completely waterproof any substrate which has existing cracking. They will still reduce the amount of water which penetrates the crack.
This works because the
- Water runoff is much improved and
- Surrounding areas don't retain moisture.
This type of saturating, flooding the surface works in many cases. The risk comes down to being able to completely seal all defects in the masonry (mortar lines, cracks in the structure)
