Polyac PMMA Waterproofing Solution for The Podium Oran Park

Client: The Podium Childcare Centre
Location: Oran Park
Project Scope: Trafficable Waterproofing Membrane for Exposed Rooftop Decks
Solution Provided: Hychem Polyac PMMA Membrane System

The Challenge

Exposed rooftop decks are highly susceptible to damage from constant exposure to rain and extreme weather conditions. If left unprotected, water infiltration can lead to structural deterioration, compromising the safety and longevity of the building. For the Podium Childcare Centre in Oran Park, the challenge was intensified during the construction fit out process, where high point loads and frequent movement from equipment installation could easily damage standard waterproofing membranes.

The Solution: Hychem Polyac PMMA Waterproofing System

Hychem was consulted to provide a long-lasting and trafficable waterproofing solution that could endure the wear and tear associated with construction activities while protecting the rooftop from weather exposure. The Polyac PMMA membrane system was chosen for its exceptional durability, crack-bridging properties, and versatility across different substrates.

Key Features of Hychem’s Polyac PMMA System:

• Extreme Durability: Polyac PMMA offers a hard-wearing layer that protects the waterproof membrane from damage during construction activities, including the installation of heavy equipment and other materials with high point loads.
• High Elongation: With 300% elongation, Polyac PMMA provides exceptional crack-bridging abilities, ensuring the membrane adapts to substrate movements without compromising waterproofing integrity.
• Substrate Versatility: This versatile system offers primer options for multiple substrates, including concrete, metal, asphalt, and damp surfaces, making it ideal for various construction environments.
• Weather Protection: By providing robust protection from rain and severe weather events, the Polyac PMMA membrane helps extend the life of the rooftop deck and prevents long-term structural damage.

Project Scope

Hychem’s Polyac PMMA waterproofing membrane was installed on the rooftop deck of the childcare centre to ensure reliable protection during and after the construction fitout process. The system’s high durability made it trafficable, meaning it could handle the movement of workers and heavy equipment without compromising its waterproofing performance.

Results

The installation of Hychem's Polyac PMMA system at The Podium Oran Park provided:

• Superior Protection: The membrane successfully shielded the rooftop deck from rain and weather exposure, ensuring long-term structural integrity.
• Construction Resilience: The high-wearing Polyac PMMA layer withstood the demands of construction fitout, protecting the membrane from damage caused by equipment and materials.
• Flexibility and Crack Resistance: With its impressive elongation and crack-bridging capabilities, the Polyac PMMA membrane adapted to substrate movement, preventing damage and leaks.
• Substrate Versatility: The versatility of the system allowed seamless application across various substrate types, ensuring a consistent and durable finish.

The Polyac PMMA membrane continues to protect the rooftop deck, providing a long-term solution for weatherproofing and heavy-duty traffic in a highly demanding environment.
