Protecting Buildings from the Ground Up
Waterproofing is a critical component of any high-performance building envelope. It prevents water infiltration, protects structural elements, and extends the life of your building. Thorpe delivers advanced waterproofing solutions for commercial, industrial, and institutional projects — whether it’s safeguarding below-grade foundations or sealing exposed plaza decks and rooftop assemblies. Our waterproofing systems are engineered to perform in the face of moisture, temperature swings, and long-term wear.
What Is Waterproofing?
Waterproofing refers to a range of systems and products designed to create watertight barriers at key points in a building’s structure — including foundations, slabs, decks, terraces, and roofing assemblies. These systems protect against water intrusion, freeze-thaw cycles, and vapor migration that can damage interiors, insulation, and critical infrastructure.
We specialize in:
- Hot-Applied Rubberized Asphalt Membranes – Ideal for large plaza decks, parking structures, and intensive-use rooftops
- Cold-Applied Liquid Membranes – Excellent for detailed areas, vertical surfaces, or when open flame is restricted
- 2-Ply SBS Waterproofing Systems – Proven protection for planters, balconies, terraces, and under green roof assemblies
- Drainage Layers & Protection Boards – Integrated systems that manage water movement and shield membranes from damage
Each system is selected based on performance needs, building use, and exposure conditions.
Waterproofing plays a critical role in many building types and is often integrated into:
- Underground parkades and basements
- Elevated decks, balconies, and terraces
- Hospitals, care homes, and data centres
- Community centres and transit infrastructure
- Industrial processing and storage facilities
- Green roofs and vegetated systems
Whether the need is structural (below-grade) or architectural (exposed decks), waterproofing ensures long-term protection and performance.
