Parging is a cementitious finish applied over exposed concrete or masonry. On residential foundations, it creates a more uniform exterior surface and gives the base of the home a finished appearance.
In Edmonton, parging is most commonly seen on the exposed portion of poured-concrete, block and properly prepared ICF foundations.
What Does Parging Actually Do?
Parging provides a serviceable exterior finish over the visible foundation. It covers normal surface irregularities, creates a consistent texture and takes the normal weather exposure at the base of the building.
It is not structural reinforcement, insulation, crack injection or below-grade waterproofing.
Is Parging Waterproofing?
No. Parging should not be treated as a waterproofing system. If a home has active water entry, drainage problems or a below-grade waterproofing issue, those conditions need to be addressed separately.
The parging itself still needs to be compatible with the substrate and properly prepared so it can bond and cure correctly.
How Is Parging Applied?
On conventional concrete or masonry, the surface is cleaned and prepared, loose or unsuitable material is removed, and compatible bonding products are used where appropriate before the cementitious finish is applied.
On a new home or addition, see our new foundation parging service. Existing damage may be better suited to localized repair or a full-wall recoat, depending on how much of the existing finish is still sound.
What About ICF Foundations?
ICF is different because the exposed surface is foam. Our ICF parging uses galvanized metal lath mechanically fastened to the ICF structure before the cementitious finish is applied.
How Much Does Parging Cost?
Pricing depends on the size of the area, condition of the existing finish, preparation, access and substrate. Our Edmonton parging cost guide provides current planning ranges.
