Parget
Definition and meaning of Parget in real estate.
Parget, or pargeting, is a thin coat of cement mortar or plaster applied to the exterior face of a masonry wall, typically a foundation, to provide a smooth finish and resist water penetration.
In more detail
This technique is commonly used on concrete block foundations to fill voids, seal mortar joints, and prevent moisture from seeping into basement walls. While it helps protect the foundation from dampness, parget is not a complete waterproofing system on its own and is often paired with drainage systems and sealants.
Over time, parget can crack, flake, or spall due to freeze-thaw cycles or shifting soil, requiring repair to maintain its protective barrier. Home inspectors look for signs of failing parget as an indicator of potential water entry issues.

Frequently asked questions
Is pargeting the same as waterproofing?
No, pargeting is a damp-proofing measure that resists moisture, but true waterproofing requires membranes and drainage systems to stop hydrostatic pressure.
How do you repair cracked parget on a foundation?
Repairing parget involves chipping away the loose material, cleaning the surface, and applying a new layer of bonding agent and mortar to the affected area.
