Brick & Masonry Waterproofing in Toronto, ON
Penetrating sealers, crystalline waterproofing, and drain tile repair to stop water infiltration in brick walls and foundations. Licensed & insured masonry contractor serving Toronto and the GTA. Free estimates.
Masonry is inherently porous — brick, mortar, and stone all absorb water. In a correctly designed and maintained masonry assembly, this is managed through drainage details, ventilation, and material selection. When those systems fail — or were never properly installed — water accumulates in the wall assembly and causes progressive damage. Elite Toronto Masonry provides masonry waterproofing and sealing services across Toronto, targeting the root causes of moisture infiltration in brick walls, foundation masonry, and concrete block structures.

Signs You Need Masonry Waterproofing & Sealing in Toronto
Chronic Damp Walls After Rain
Walls that are consistently damp or show water staining after rain events indicate that water is entering the masonry assembly faster than it can drain or evaporate. Identifying the entry point — cracked mortar, failed coping, missing flashing, or an absent sealer — is the starting point.
Efflorescence and Salt Deposits
White powdery deposits on masonry surfaces are a reliable indicator of active water movement through the masonry. The water dissolves soluble salts from the mortar or brick and deposits them on the surface as it evaporates.
Our Masonry Waterproofing & Sealing Process in Toronto
Moisture Source Identification
No waterproofing product or sealer substitutes for addressing the source of moisture entry. We use visual inspection, moisture meters, and a hose-and-wait test protocol to identify whether water is entering through failed joints, cracked brick, missing copings, or failed flashings. We address the source first — sealing over a defect simply traps water behind the sealer.
Structural Repairs & Joint Repointing
Failed mortar joints, cracks, and delaminated sections are repaired before any surface treatment is applied. Penetrating sealers work through intact masonry surfaces — if the substrate has cracks or voids, the sealer cannot bridge them.
Sealer or Waterproof Membrane Application
Once structural deficiencies are repaired, the appropriate protective system is applied. For above-grade brick walls, a penetrating silane-siloxane sealer (typically 40% solids, water-based) is applied by brush or airless spray in two coats. For below-grade or consistently saturated conditions, a crystalline waterproofing system (Xypex, Kryton) or a drainage membrane is more appropriate.

Masonry Waterproofing & Sealing FAQs — Toronto Masonry Answers
Will a masonry sealer stop all water from entering my wall?
Penetrating sealers significantly reduce water absorption but cannot bridge cracks, failed mortar joints, or other structural defects. A sealer applied over an intact, properly pointed masonry surface will reduce water infiltration by 90%+ in most test scenarios. Applied over a wall with failed joints or open cracks, it provides minimal benefit.
