Protect Your Richmond Hill Home from Foundation Cracks and Costly Water Damage
Discover certified waterproofing systems designed to stop leaks, stabilize your foundation, and protect your home’s structure for decades.
Built Right. Beneath the Surface.
When water starts to seep into your basement, it’s not just a small problem — it’s a signal that your home’s foundation is under pressure. Richmond Hill’s clay-heavy soil, high water table, and freeze-thaw cycles make homes especially vulnerable to moisture intrusion and foundation stress.
At SDM Contractor, we help homeowners protect their properties from the ground up. Our certified waterproofing systems are designed to stop water at its source, restore structural integrity, and create dry, healthy, livable spaces that last.
We don’t just patch problems — we prevent them.
Why Waterproofing in Richmond Hill Matters
Richmond Hill’s growing residential landscape includes both older homes and new builds — and both face their own waterproofing challenges. Older foundations often suffer from cracked concrete and outdated weeping tile systems, while new homes are built on dense clay that traps water.
Without proper waterproofing, moisture will eventually find a way inside — often leading to:
- Foundation cracks and structural weakening
- Recurring basement flooding during seasonal storms
- Mold growth and poor indoor air quality
- Decreased property value and failed home inspections
Waterproofing isn’t just about managing water — it’s about protecting your investment, your comfort, and your peace of mind.
Our Proven Waterproofing Process
Every home is different, and so is every waterproofing plan. At SDM Contractor, we start by identifying exactly what’s happening beneath your home, then tailor a system that provides lasting protection — not temporary fixes.
We begin with a detailed inspection of your foundation, drainage, and moisture exposure points. Using moisture meters and visual mapping, we pinpoint the cause of leaks, cracks, and water buildup.
Our assessment includes clear documentation — you’ll know exactly where the problem starts and how we plan to correct it.
Based on your foundation type and home layout, we recommend a system built for durability and code compliance.
Interior Waterproofing
Best for finished basements or minor seepage.
- Installs an interior drainage system and vapor barrier
- Includes sump pump setup for groundwater removal
- Fast installation with minimal disruption
Exterior Waterproofing
Best for long-term foundation protection.
- Excavation around the exterior foundation walls
- Application of a waterproof membrane and drainage board
- Replacement of old or clogged weeping tile systems
- Backfill with gravel and regrade for proper water runoff
Additional Protection Options
- Foundation Crack Injections: Seals structural cracks with epoxy or polyurethane
- Sump Pump & Backwater Valve Installation: Prevents flooding and sewage backup
- French Drain Systems: Diverts groundwater away from the home’s perimeter
Every system is customized, installed by certified technicians, and designed to last for decades.
SDM Contractor’s work is completed entirely in-house. Our technicians are certified, experienced, and trained in waterproofing systems that meet or exceed Ontario Building Code standards.
We don’t subcontract — meaning every stage, from excavation to inspection, is managed by our own experts. The result is a higher standard of accountability and workmanship.
