Tuckpoint before Treating

Before doing any work around your basement walls (such as insulating, waterproofing, etc.), make sure to tuckpoint the block.

Tuckpointing is the recementing of mortar joints that have come apart over time.

In a crawl space that we just finished, we tuckpointed for a good 2 hours. Since we were going to adhere insulation board to the block, we first had to do whatever we could to stop the air flow as well as prevent as much potential water breach as possible.

If you use a hydraulic cement, the mortar will dry much more quickly. However, we still suggest waiting a full 24 hours for the best cure.
