Commercial Waterproofing and Caulking Services in Toronto
At Aquamaster Plumbing, we provide a full range of commercial waterproofing services designed to meet the needs of buildings both new and existing. Our team has experience with a wide variety of commercial properties, including shopping centers, apartment buildings, warehouses, schools, hospitals, and other institutional spaces.
- ICF waterproofing: We often work with partners like custom home builders to waterproof properties that are still under construction with insulated concrete foam (ICF).
- Blindside waterproofing: Widely known as pre-applied basement waterproofing, blindside waterproofing is an excellent choice for commercial properties in the initial stages of construction with scenarios like zero-lot-line foundations that complicate their construction.
- Crack repair: Our experts can perform foundation crack repairs for damaged sections of walls and floors. We can help evaluate the extent of foundation damage and recommend an appropriate solution – from sealing foundation cracks with epoxy injection to solutions like crack stitching.
- Other commercial waterproofing services: From drainage system maintenance and catch basin cleaning to sump pump installation and commercial plumbing, Aquamaster provides our clients with a full suite of services.

Waterproofing for New Builds and Blind-Side Jobs
New construction brings its own set of waterproofing demands. For ICF foundations, deep urban excavations, or sites with minimal access, we use blind-side waterproofing systems that get placed before backfill. We coordinate directly with your engineers, architects, and general contractors to make sure everything fits into your build schedule.
Specialty Work and Structural Support
Some of the most flood-prone areas in a building are below grade and out of sight. This includes elevator pits, tunnels, and mechanical rooms. We waterproof these spots and, if needed, we also perform floor lowering and underpinning to increase ceiling height while keeping the foundation strong.
Every job starts with a free site visit. We inspect the property, highlight high-risk zones, and lay out a clear step-by-step plan. Permit applications, safety planning, and municipal code compliance are all handled by us so you can focus on keeping your building running.
How We Handle Commercial Waterproofing Jobs
Waterproofing at scale requires more than sealing a few joints. It is about doing the work without halting your operations or compromising safety.
- Minimizing Disruption – We plan our schedules around your hours. We know businesses cannot afford shutdowns, so we build work plans that keep you open while we handle the job.
- Permit Handling- From lane closures to curb cut approvals, we sort through city paperwork and get permits processed before crews arrive on-site.
- Safety Measures – We put up protective hoarding, mark out work areas clearly, and maintain job sites that stay clean and safe for staff, tenants, and the public.
- Vacuum Excavation – Digging around underground utilities requires precision.
- We use vacuum – trucks to expose lines safely and move faster without risking costly damage.
- Surface Restoration – Once the waterproofing is done, we repair every surface to match its original state. Whether it is interlock pavers or poured concrete, we leave it clean and professional.
