Complete Remedial Waterproofing Services
Waterproofing failures rarely stop at the membrane. Water can travel through building interfaces, screeds, joints, penetrations and adjacent finishes before becoming visible internally. As a remedial building and construction company, Remicon can manage the complete rectification process rather than treating waterproofing as an isolated trade.
Our waterproofing and water damage rectification services can include:
- Water ingress investigations and initial condition reporting
- Pre-works water testing, flood testing and targeted leak testing where suitable
- Removal of tiles, screeds, coatings and failed waterproofing systems
- Substrate preparation and localised concrete or crack rectification
- Falls and drainage preparation where included within the rectification scope
- Internal wet area waterproofing
- External balcony and terrace waterproofing
- Podium and planter box waterproofing
- Sheet membrane waterproofing systems
- Liquid-applied waterproofing systems
- Waterproofing to junctions, penetrations, upturns and terminations
- Tiling, screeding and associated finishes
- Sealant and silicone works
- Painting, plaster repairs and internal water-damage make-good
- Post-installation water testing where appropriate
- Photo documentation, staged reporting and project close-out
Internal & External Waterproofing
Internal waterproofing
Remicon undertakes remedial waterproofing to internal wet areas where failed or inadequate systems are contributing to leaks, moisture damage or deterioration. Depending on the existing construction and investigation findings, works may include bathrooms, laundries, showers and other tiled wet areas. Because we can also complete demolition, substrate repairs, tiling, silicone, painting and make-good, the client can engage one contractor through the full rectification process.
External waterproofing
External waterproofing requires careful consideration of exposure, drainage, movement, interfaces and termination details. Remicon undertakes waterproofing repairs and replacement systems to balconies, terraces, podiums, planters and other external building elements, with the system selected to suit the substrate, finished surface, exposure and project requirements.
Sheet Membrane & Liquid-Applied Waterproofing
Remicon is experienced in both sheet membrane and liquid-applied waterproofing systems. We do not force every project into one membrane type. The proposed system is selected around the existing building, access, substrate, programme, finished surface, expected movement, required durability and client budget.
Sheet membrane waterproofing
Sheet membranes can provide a controlled and consistent membrane thickness and are particularly valuable where a robust, high-performance waterproofing system is required. Remicon's sheet membrane capability includes premium systems such as ARDEX WPM 1000 and WPA Aqualay, subject to project suitability and manufacturer requirements.
Liquid-applied waterproofing
Liquid-applied membranes remain an effective option across many internal and external waterproofing applications, particularly where complex detailing, penetrations or geometry make a continuous applied system advantageous. Remicon works with suitable liquid-applied systems from established manufacturers, selected according to the specific application rather than price alone.
Featured Waterproofing Systems
ARDEX WPM 1000 WeldTec™ Waterproofing Membrane
For projects requiring a premium sheet membrane solution, Remicon can install ARDEX WPM 1000. ARDEX describes WPM 1000 as a weldable, polypropylene-lined waterproofing sheet membrane for internal and external non-exposed applications. Its laps and seams are heat-welded, producing a consistent membrane layer suitable beneath tiled or screeded finishes and other approved protected applications.
The current ARDEX technical information identifies WPM 1000 as compliant with AS 4654, AS 4858 and AS 2904, with a consistent 1.2 mm membrane thickness. ARDEX also states that flood testing, tiling or screeding may commence 60 minutes after installation completion when the system is installed in accordance with its requirements.
For remedial projects, WPM 1000 can be particularly attractive where the client is seeking a high-end waterproofing system with controlled membrane thickness, welded seams and compatibility with selected ARDEX tiling systems.
WPA Aqualay Sheet Waterproofing System
Remicon also installs WPA Aqualay, supplied through Bayset. WPA Aqualay is a flexible sheet waterproofing membrane with an EBA core laminated with non-woven geotextile fleece. Bayset identifies the system for internal wet areas, balconies, terraces and other tiled waterproofing applications, with finishes such as tiles, screeds and toppings able to be installed over the system in accordance with the manufacturer's technical requirements.
WPA Aqualay is CodeMark certified for internal and external above-ground waterproofing applications. Its flexible construction also provides crack-isolation properties, making it a useful system to consider where substrate movement and finished tiled surfaces form part of the remedial design.
Accredited Installation & Manufacturer Involvement
Remicon is currently an accredited installer for ARDEX and Bayset/WPA waterproofing systems. We work closely with product manufacturers and technical representatives so that the selected system, substrate preparation, detailing and application methodology are aligned with the relevant manufacturer requirements.
Where the project and system allow, manufacturer or third-party technical review and inspection can be incorporated before critical stages are covered. This creates an additional quality-control layer and helps provide the client with confidence that the waterproofing installation has been approached as a complete system rather than simply as a membrane application.
Pre- and Post-Works Water Testing
Where suitable for the building and waterproofing system, REMICON can conduct pre-works and post-works water testing. Pre-works testing assists with establishing site-specific evidence and differentiating potential ingress paths before demolition or rectification. Post-works testing can then provide an additional verification step before final finishes or close-out, subject to the membrane system, curing requirements and site conditions.
Testing may include controlled flood testing, targeted water application, moisture observations and photographic documentation depending on the issue being investigated. The methodology is selected to suit the building and is documented so the client receives clear, site-specific results rather than assumptions.
Our Waterproofing Rectification Process
1. Investigation & reporting
Inspect the affected areas, review visible defects and water-damage patterns, document conditions and determine whether further testing or opening-up is required.
2. Water testing & source identification
Where appropriate, undertake controlled testing to help isolate likely water ingress paths and establish baseline observations.
3. Rectification scope & system selection
Develop a practical scope covering demolition, substrate preparation, membrane system, interfaces, finishes and testing. Present suitable system options where budget and project requirements justify alternatives.
4. Demolition & substrate preparation
Remove failed finishes and waterproofing as required, expose the substrate, prepare surfaces and address identified defects included within the scope.
5. Waterproofing installation
Install the selected sheet or liquid-applied waterproofing system in accordance with the applicable manufacturer requirements and project details.
6. Quality-control hold points
Document critical stages and, where arranged, coordinate manufacturer/third-party technical review before the system is covered.
7. Testing & reinstatement
Undertake appropriate post-installation testing after required cure periods, then proceed with screeds, tiles, sealants and associated finishes.
8. Internal make-good & close-out
Rectify associated internal water damage where included, complete painting/plaster/finish works, provide photo records and close-out documentation.
Waterproofing Solutions Around the Project Budget
Not every building requires the same waterproofing system, and not every client has the same budget. REMICON can assess suitable system options ranging from efficient liquid-applied solutions through to premium sheet membrane systems such as ARDEX WPM 1000.
Our objective is not to reduce quality to meet a price. It is to select the strongest fit-for-purpose system available within the client's approved budget, while maintaining appropriate preparation, detailing and workmanship. Where a lower-cost option would compromise the required performance or warranty pathway, we will identify that risk rather than simply reduce the scope.
Water Damage, Mould & Internal Rectification
Waterproofing failures can result in damaged plasterboard, skirtings, paint finishes, flooring and other internal materials, and prolonged moisture can create conditions conducive to mould growth. Remicon can investigate the water source and coordinate the associated water-damage rectification and internal make-good once the source has been addressed.
Where mould is identified or suspected, the required response depends on the extent, affected materials and site conditions. Remicon can coordinate appropriate assessment, removal or specialist remediation where required as part of the broader rectification works. This allows the client to manage the waterproofing failure and its downstream damage through a coordinated remedial process.
