Does Parging Keep Water out?

Is Parging the Same as Waterproofing? No. ... Though it's not technically meant for waterproofing, a parge coat does make a water-resistant barrier. When done right, it helps the rest of the exterior finish do its job to keep the house dry.

Does parging waterproof?

While parging is not waterproofing, and shouldn't be thought of as a good enough barrier in and of itself, it can be an important player on your home's waterproofing team. Parge coats, properly applied, can act as a barrier against rain and snow for the foundation walls that rise above the soil.

What is the point of parging?

Parging provides an extra layer of insulation against rain, wind, ice and snow. But more importantly, it helps protect the foundation from those elements. When your foundation has seams and holes and pits, the expansion and contraction that come along with freeze and thaw cycles can cause pieces to crack and fall away.
