Parging

Our professional application creates a smooth, durable finish. Our meticulous process ensures long-lasting results.

A protective mortar coat for foundation walls

Parging is a thin layer of cement-based mortar (typically 3-6mm) applied to foundation walls and concrete blocks. It protects against moisture and improves appearance—turning rough concrete into a smooth, finished surface.

Traditional parging uses Portland cement, hydrated lime, fine sand, and water. Modern applications add polymer additives for better adhesion and flexibility, helping it withstand Ontario’s freeze-thaw cycles.

When Foundation Parging Needs Repair

Problems with your foundation can undermine the structural integrity of your home. Spot these warning signs early to avoid expensive repairs later.

Parging Flaking Off Foundation Walls
Large sections peeling or falling off expose concrete to moisture and damage due to lost adhesion or parging applied over dirty/wet surfaces.

Cracks Allowing Water Infiltration
Cracks wider than a hairline let water reach the foundation, leading to spalling, basement dampness, and mold.

Tapping on Foundation Makes Hollow Sound
A hollow or drumming sound means parging has separated from the wall, trapping moisture, even if it looks intact.

Horizontal Cracks in Basement Walls
Lateral pressure from soil or water may be pushing the wall inward. This requires immediate stabilization before the wall bows or collapses.

Bowing or Bulging Basement Walls
Walls curving inward are under structural stress from hydrostatic pressure. This is a serious issue, requiring immediate and professional attention.

Water Entering Through Foundation
Water seeping through cracks or walls causes interior damage, mold growth, and rapid structural deterioration.
