RPA EPDM is the Ultimate Waterproofing Membrane for Modern Architecture
As an architect, the integrity of your building envelope relies heavily on the waterproofing specification. RPA Waterproofing specializes in RPA EPDM roofing systems—providing you with a high-performance membrane that protects your design from the basement to the roof, without forcing you to compromise on aesthetics.
Unrestricted Design Flexibility
Traditional waterproofing can dictate structural shapes and limit material choices. EPDM’s exceptional flexibility and seamless application give you the freedom to design complex, modern geometries
Green Architecture
Highly durable and inherently root-resistant, making it the premier specification for roof gardens and integrated planter boxes.
Minimalist Flat Roofs
Achieve clean architectural lines for flat roofs and exposed beams with a membrane that guarantees a secure, watertight finish on zero-degree falls.
Complex Detailing
Easily conforms to intricate shapes, making it the ideal solution for concealed box gutters, flush balcony wraps, and precision flashings.
Heritage & Renovation
Highly adaptable for delicate preservation projects, including slate roof and asbestos encapsulation.
Engineered for the African Climate
Specify a system that actively minimizes future liability. EPDM is structurally designed to endure the thermal shock, intense UV radiation, and extreme weather fluctuations unique to the South African climate.
Substrate Versatility: Offers secure installation across diverse architectural materials, including concrete, steel, and complex wooden roof assemblies.
Lifecycle Cost-Efficiency: EPDM boasts an exceptionally long lifespan compared to traditional torch-on systems, delivering long-term ROI to your clients and protecting your firm’s reputation for quality.
RPA Reliability: By specifying RPA EPDM through RPA Waterproofing, you are selecting a globally recognized benchmark for durability and continuous leak protection.
Partner with RPA: Building Envelope Solutions
Led by professionals with a rigorous engineering background, RPA Waterproofing understands the structural mechanics behind your architectural design. We know that true waterproofing is never a reactive “band-aid” fix. Instead, we analyze the entire building envelope, from foundational dynamics to complex roof geometries to engineer a holistic, integrated waterproofing solution that performs for the lifespan of the building.
