Sheet Membrane Systems
At Instant Waterproofing, we specialise in the supply and installation of sheet membrane waterproofing systems, delivering long-lasting and reliable results for both residential and commercial projects.
Sheet membranes are pre-manufactured rolls of waterproofing material that are applied to a prepared surface to form a durable, watertight barrier. Unlike liquid systems, sheet membranes provide controlled thickness, uniform coverage, and excellent resistance to movement and tearing.
We work with a wide range of sheet membrane systems, including:
• Bituminous membranes – strong, flexible, and highly resistant to punctures, ideal for roofs, basements, and retaining walls.
• PVC and TPO membranes – lightweight, UV-resistant, and suitable for exposed outdoor areas such as podiums and roof decks.
• Butyl and EPDM membranes – highly elastic, making them perfect for areas that experience structural movement or vibration.
Our team ensures every installation follows NCC requirements, Australian Standards (AS 4654 & AS 3740), and manufacturer guidelines. Sheet membrane systems are particularly suitable for:
• Balconies and terraces
• Podium slabs and planter boxes
• Rooftops and carparks
• Basements and below-ground structures
We pride ourselves on precision installation, including correct detailing at corners, joints, and penetrations. The result is a robust waterproofing system designed to last the life of the structure.
