Membrane Waterproofing for Commercial Construction
Floortek installs waterproofing membrane systems for rooftop decks, podium slabs, wet areas and below-slab applications across South Australia. We specify trafficable and non-trafficable systems based on substrate condition, exposure class and end use.
We work alongside builders and head contractors from design stage through to practical completion. Systems are installed to AS 3740 and AS 4858. No shortcuts on detailing — penetrations, corners and drains are treated as carefully as the field.
System Options
- Trafficable liquid membrane (rooftops & podiums)
- Non-trafficable membrane (planter boxes, below-slab)
- Wet area systems (AS 3740 compliant)
- Cementitious waterproofing (tanking)
- Sheet membrane systems
- Penetration & detail work
Applications
Rooftop Decks
Trafficable membranes for occupied rooftop spaces and plant rooms
Podium Slabs
Below-slab waterproofing for podium car parks and structural decks
Wet Areas
Bathrooms, showers and amenities to AS 3740
Planter Boxes
Non-trafficable systems for landscaped and garden areas
Car Parks
Traffic-bearing deck coatings and waterproofing systems
Balconies & Terraces
Exposed deck systems with falls and drainage detailing
Our Process
Substrate Assessment & Moisture Testing
We assess the concrete substrate, test for moisture content and identify any defects requiring repair before membrane application.
Surface Preparation
Grinding, cleaning and crack injection as required to achieve a sound, contaminant-free substrate.
Primer Application
Substrate primer applied to specified coverage to ensure membrane bond and reduce risk of pinholes.
First Membrane Coat
Liquid membrane applied by roller or squeegee to specified wet film thickness.
Reinforcement & Detailing
Geotextile reinforcement embedded at corners, coves and penetrations. All terminations and upstands detailed to specification.
Second Coat & Inspection
Final membrane coat applied. Flood test or electronic inspection completed prior to handover.
