Membrane Waterproofing For Commercial & Multi-Storey Properties
Liquid membrane waterproofing offers a flexible, durable and fully adhered barrier against both water and environmental damage.
Unlike sheet membranes, liquid membranes can be applied seamlessly to complex surfaces, creating a reliable and consistent protective layer.
Avant Access delivers professional waterproofing services for strata, commercial and industrial properties, focused on minimal disruption and unrivalled attention to detail. We tailor each system to suit the needs of your building, whether it’s a balcony, roof, podium or plant room.
Roof Waterproofing For Long-Term Protection
Flat concrete roofs are particularly prone to water pooling and UV exposure.
Our liquid-applied roof waterproofing systems form a barrier that is resistant to cracking, movement and environmental breakdown.
Ideal for both new builds and remedial application, our roof solutions help to prevent leaks, structural damage and costly maintenance – all while maintaining a clean and low profile finish.
Balcony Waterproofing & External Surfaces
Waterproofing terraces, balconies and outdoor areas is essential for water ingress prevention and internal structure protection.
At Avant Access, we specialise in external waterproofing solutions for balconies – including under-tile membrane systems – to ensure moisture stays out and surfaces remain safe. Our seamless membrane finish ensures no weak points, making it ideal for high-traffic and exposed areas.
