ARDEX WPM 310

ARDEX RA 88 PLUS

Situated in Berkeley, New South Wales the Nan Tien Temple is the largest Buddhist temple in the southern hemisphere. Constructed in October 1995, this multi-award winning Temple has become a must visit venue for local and international tourists, and also acts as an important cultural centre bridging different cultures.

The public spaces below the main and front Temple showed signs of water ingress and moisture. Urgent waterproofing remediation was required for over 820m² of concrete walkways, plus an additional 900 lineal metres of threads and risers on the multiple staircases.

Unique elements:

Since the venue encounters high amounts of daily foot-traffic, the project comprised of two stages to ensure the Temples remained accessible.

As the only access to both the main and front Temples are via staircases, all stairs had to be split in two sections during rectification works to ensure public access remained. One of the biggest challenges was the precise membrane detailing required for these areas and to utilise a membrane solution that could provide a smooth transition between the differing stages to allow for direct stick tile adhesion on all staircases.

Solution:

The ARDEX Weldtec^TM WPM 1000 membrane provided the waterproofing solution to meet the projects many challenges. ARDEX Australia worked closely with JMB Waterproofing Solutions, who provided a high attention to detail and commitment to waterproofing excellence throughout the entire project. The ARDEX Weldtec^TM WPM 1000 was installed under direct screed and tile applications, but when the ARDEX Weldtec^TM membrane was to remain UV exposed in specific areas, the ARDEX WPM 300 and ARDEX WPM 310 protecting coating were able to be utilised to ensure the structure remains protected and waterproofed for many years to come.

“It was great to collaborate and work alongside ARDEX and Urban Core. Working seamlessly together on this project, we appreciated the support from ARDEX representatives and the technical department. The partnership highlights our dedication to accuracy in every aspect of our work.”

Joe Brady, Director at JMB Waterproofing Solutions.

New Doha International Airport, Qatar

Project size:

144,000m²

Project information:

Formerly known as New Doha International Airport (NDIA), Hamad International Airport was opened in 2014. The new airport has been designed and built to accommodate 50 million passengers per year, with estimates suggesting up to 93 million per year. Annual aircraft movement is expected to exceed 320,000, with over 2 million tonnes of cargo passing through the airport, making it the second largest airport in the region. This seven-year construction project would involve a location approximately 36 square kilometres and require nearly 40,000 workers on a complex job site.

At varied thicknesses from featheredge up to 40 mm, more than 4,500 tonnes of ARDEX K 15 covering 144,000m² was used. This market leading sub-flooring product was installed throughout the entire project due to the products continuous proven history, superior product performance, with the ability to provide complete levelness and flatness needed later for various finished flooring and carpet. Jobsite coordination was imperative to ensure the project remained on schedule and with the products ease of application performance the 12 teams of 8 to 10 workers were able to flawlessly install an average of 200m² to 300m² daily.

Olympic Aquatic Centre, London

Project size:

The product’s user-friendly workability, non-sag performance, and outstanding coverage allowed installers to work more quickly and efficiently to meet the project requirements.

Therme Lindau, Germany

Installer/Applicator: Reiser GmbH in Bad Saulgau
Architect: 4a Architekten GmbH from Stuttgart

On one of the most beautiful stretches of Lake Constance, the new Therme Lindau invites you to swim and relax. Spacious indoor and outdoor areas with over 20 pools – from the plunge pool and the 50-meter swimming pool to the brine pool – offer the greatest variety. Themed saunas and restaurants top off the beautiful offering.

As grand as the design of the spa and the view, so were the challenges the tile setters faced. “As with any swimming pool, first and foremost everything revolves around impermeability,” explains master tiler Christoph Reiser of Reiser GmbH in Bad Saulgau. “Then there are the many special features and details: the brine pool with its aggressive water, the stainless-steel sports pool, the water bars, the 30 x 60 cm tiles as well as the many mosaic tiles. We laid some of them in organic shapes.“

Challenges

Seemingly floating: If you look out over the large pool through the glass front, the water surface connects with Lake Constance. The effect is similar to that of an infinity pool. Before the elements come together in such a seemingly weightless way, the pool surround made of natural stone had to be precisely installed. “My employees measured it on site – and then had it manufactured so that the pieces interlocked like a puzzle,” Reiser continues.

The connection of the tile to the large stainless-steel basin came with its own challenges and ARDEX employees visited the construction site regularly. “We were there again and again with our specialists to discuss the requirements,” says Jochen Polonyi, Sales Representative of ARDEX Germany. “This allowed us to understand the situation and propose individual solutions in cooperation with our Technical Service and the research and development centre.“

Solution

The procedure they came up with was unique and perfect for the situation: The craftsmen first degreased the stainless-steel rim and bonded the sealing membrane with the heavy-duty sealing compound ARDEX S2-K PU. The adjacent screed edge was neatly filled with ARDEX A 46 stable exterior filler so that it was flush with the stainless-steel edge. Then the recesses were further sealed with epoxy resin and covered with sealing tape.

The brine pool is a special highlight of the spa – and at the same time another challenge for waterproofing with its minerals and salts. The tilers were able to work with the heavy-duty waterproofing ARDEX S2-K PU once again. “We are absolutely thrilled with the quality,” says master tiler Reiser. “Above all, not having to sand is a huge advantage. It saved us time and we didn’t have to dispose of any leftover sand.”

In the brine pool, as in all other wet areas, the epoxy adhesive ARDEX WA was used. It is particularly suitable for areas subject to high chemical or mechanical stresses, such as swimming pools and spas. The surge tanks were sealed with the flexible sealing slurry ARDEX S7 PLUS. The advantage: the consistency can be variably adjusted. This meant that the waterproofing could be sprayed by machine onto ceilings and walls in the surge water tanks.

In total, 12,000 square meters of tiles and mosaics had to be laid. And the delicate manual work takes time. ARDEX S8 FLOW was specifically developed to level and waterproof large areas fast and can be applied with a squeegee standing up. “My employees really want to work with ARDEX S8 FLOW and always ask for it,” says tile professional Reiser. “It’s just easy to work with, and it goes on faster.” To waterproof and level the substrate for the 30 x 60 cm tiles, ARDEX S8 FLOW was applied in two coats.

During the construction phase, there were always changes and additions. Like the bathhouse that was additionally built. “We fully trusted the architect’s vision. Any new idea he brought up, we made it happen,” says Reiser. All the enclosures around the sauna ovens were to be clad in porcelain stoneware tiles. “It was important that the tile adhesive was also heat-resistant.” That’s why ARDEX X 77 was used. The fibre reinforced MICROTEC flexible adhesive is ideal for bonding tiles made of stoneware and porcelain stoneware, concrete and natural stone slabs.

After 16 months of work with an average of 15 employees, Christoph Reiser is pleased with the result. “It was a great team effort on the construction site. Everyone did their part.” The spa has been open to visitors since the summer of 2021.

North Bondi Residential Apartments, Sydney

Installer/Applicator: Structural Building Management
Specifying Engineers: Cardno

North Bondi is in the eastern suburbs of Sydney; located on the coast of New South Wales and a short distance away from the world-famous Bondi Beach. Being a mostly residential area, a block of apartments was recently brought to the attention of the team at Structural Building Management as needing repairs to the structure of the building.

Challenges
As this building was situated extremely close to the Tasman Sea, this block of residential units was heavily affected by what is known as concrete spalling AKA “concrete cancer” – the rusting of steel reinforcement contained within a concrete slab. Balconies and columns throughout the building were affected and treatment was required to fix the issue.

This residential building still required access for residents to go about their daily lives and activities, so minimal disruption was required with a relatively quick turnaround. On top of that, a solution was required to slow the progression of any future concrete spalling / (cancer) in these rehabilitated areas.

Solution
In conjunction with the specifying engineers, Cardno, ARDEX Australia provided a concrete repair system to remediate the current issues as well as assisting in the prevention of the steel and concrete from becoming damaged so quickly again. The team at Structural Building Management were engaged to carry out rectification works to the unit block.

The affected areas for rectification were broken-out and removed, prior to being primed with ARDEX WR Prime (as this product enhances the performance of the following repair mortar and promotes tenacious adhesion to the host surface).
Approximately 2500 litres of ARDEX BR 340 Microtec® fibre-reinforced structural concrete patching and repair mortar was installed. The BR 340 repair mortar contains an active corrosion inhibitor (for ongoing protection of the reinforcement bar within the repair area).

To assist in retarding any future damage to the reinforcement within the concrete, ARDEX BRX 60 LO sacrificial anodes were installed. ARDEX BRX 60 LO are ‘sacrificial’ zinc anodes that provide control to limit corrosion rates of bars embedded in the concrete.

It took approximately 12 weeks for Structural Building Management to complete repairs and to rectify the issues caused by concrete cancer.

Miami Aquatic Centre, Miami, Gold Coast

Primary Contractor: Hutchinson Builders
Tiling Contractor: Base Tiling
Commercial Pool Builder: Ozcrete Pools Pty Ltd

The Miami Aquatic Centre located in the Gold Coast has been the place of leisure and activity for many locals since 1976 and has been the launching pad for some of Australia’s greatest Olympian swimmers. At 350,000 annual visitors, it has the second highest number of aquatic centre visitors in the Gold Coast.

Challenges
The aquatic centre has remained the same with no real large-scale renovations taking place since construction in 1976. Due to this and the number of visitors every year, a redevelopment was proposed and accepted to update the facilities.

As part of this renovation, a new 10-lane, 50 metre exterior Olympic pool and a smaller inside pool was to be built. This totalled over 3,000 m² of tiling required to complete this project, within a period that would allow visitors to resume activities without too many disruptions.

The new pools needed to be built as per Australian standards (AS3958). An adhesive was required to cover at least 90% between the substrate and the back of each tile and movement joints were required at a minimum size of 6mm.

Solution
The tiling contractor approached ARDEX for a solution with a successful track record. ARDEX X 77 was specified because of its proven record of success in large international projects like the London Olympic Games pool.

ARDEX X 77 fibre-reinforced adhesive contains Microtec® technology which improves adhesive strength, reducing the effect of shear strain and stress on tiling systems. Base tiling was very impressed with the non-sag and long open times of the ARDEX X 77.

With the ARDEX X 77 they were able to commence tiling at the coping tile and work downwards, something they’ve never been able to do before with other tile adhesives without significant slumping.

The pool was grouted using ARDEX FG 8 flexible coloured grout. ARDEX FG 8 has a strong uniform colour that reduces efflorescence, is polymer modified which reduces the likelihood of cracking and is mould resistant and water repellent. ARDEX Grout Booster was also used and contains ARDEX Grout Shield to help combat mould growth.

ARDEX ST neutral cure and non-staining silicone was applied to the movement joints. ARDEX ST is UV, weather, and water resistant, and contains fungicides to combat any mould growth.

Little Lane Early Learning Centre, Manly

Little Lane Early Learning Centre is a purpose built, architecturally designed childcare facility located in Manly, NSW. The centre provides a premium service to the area, focusing on children’s early learning and childhood education from 0-5 years.

Unique Elements
The 3-storey building features a commercial kitchen, 14 classrooms, 3 large outdoor learning environments including a roof garden area, and below ground level car park. Specific project stages required a fast turnaround, hence why Systems Ardex was used on this project.

The outdoor learning and play area, and planter boxes are located over habitual spaces. These critical areas required a reliable and proven waterproofing system to ensure the entire area would remain waterproof for many years to come.

The below ground car park presented a different challenge as the building is situated near proximity to Manly beach. This area is susceptible to continuously changing underground water pressure and water ingress due to the ever-changing tides. A waterproofing system was required that could withstand those pressures while protecting the surrounding environment and structure from damage.

Solution
ARDEX was chosen because of our systems approach. A complete ARDEX waterproofing system was specified to not only provide a quick turnaround, but for reliability as well.

For the outdoor learning and play area, and planter boxes, 1200 sqm of a system comprising of ARDEX WPM 1000 and ARDEX Root Repell waterproofing membranes was installed. Both waterproofing membrane systems are specially designed for this type of external environment.

ARDEX WPM 1000 is a unique and extremely versatile heat weldable waterproofing membrane. ARDEX Root Repell is designed specifically for areas exposed to soil and plants, containing a root inhibitor that repels root growth without killing the actual root.

Approximately 2800 sqm of ARDEX WPM 1500 tanking membrane was installed in the below ground car park. ARDEX WPM 1500 is designed specifically for below ground tanking applications and has excellent flexibility, elongation and water migration resistance.

Overall, the ARDEX specification made it easier for the architect, builder, and applicators to purchase, install, and warrant the materials.

The Pool of Reflection, Sydney

LOCATION: Hyde Park, Sydney, Australia.
BUILDER: Structus Pty Ltd
WATERPROOFING: Soleace Waterproofing Pty Ltd
TILING: Nationwide Tiling

ARDEX Australia is proud to be involved in the restoration works surrounding the 1450sqm ‘Pool of Reflection’ Memorial which is located in Hyde Park in Sydney’s CBD. The upgrade of the physical pond was undertaken to repair leaks and improve water circulation and filtration. At each stage of the project, the Memorial was visited by dedicated ARDEX staff to provide support.

The Pool of Reflection is a peaceful space where passersby may pause for a moment of quiet contemplation. For manyveterans the still waters of the ‘Pool of Reflection’ evoked memories of the Somme River and its accompanying canals in France. The AIF (Australian Imperial Force) fought some of its bloodiest battles in the Somme Valley in 1916, 1917 and 1918.

CHALLENGE:
There were various challenges that ARDEX had to overcome in this project. One of the key challenges included containing water within the pool while at the same time keeping water out – the pool has expansion joints in the substrate and the concern was that the water coming up from the ground would push the moisture out.

SOLUTION:
ARDEX advised that an outlet was required before the pool was lined. This was done by running the ARDEX WPM 1000 Undertile Butynol Waterproofing Membrane parallel with the expansion joints, resulting in the membrane being turned into a joint with a stainless steel angle and then sealed off with ARDEX RA 88 Multipurpose Epoxy Repair Adhesive. A system of the ARDEX DS 60 Decoupling Mat was installed under a strip of ARDEX WPM 1000 to allow the gas and moisture build-up to escape. Also, ARDEX arranged for ARDEX WPM 1000 to be pre-cut to suit each of the joints, saving on time.

UNIQUE ELEMENTS:
The Pool of Reflection’s tiles could be bonded directly below the water line to the ARDEX WPM 1000 Undertile Butynol Waterproofing Membrane using ARDEX’ X 18 Fibre-Reinforced Flexible Non-Slump Wall and Floor Tile Adhesive, an adhesive that adds strength to a tiled area in addition to ARDEX E 90 Admix for Cement-Based Tile Adhesives. The installation was completed using ARDEX’ new ARDEX EG 15 Easy Clean High Performance Epoxy Grout providing contractors ease of use in addition to a complete system solution.

The installation of the main ARDEX WPM 1000 membrane was carried out by being fully glued with ARDEX WA 98 Butynol Adhesive. At the rear of the pool there is an overflow which the granite stone plinth has been fixed with ARDEX WA 100 Two Part Epoxy Adhesive for Natural Stone.

Austin Apartment Pool Refurbishment, South Brisbane

PROJECT MANAGER: Hutchinson Builders
CONTRACTOR: Peter Johnson Tiling

Located in South Brisbane, Queensland, Austin Apartments is a 21-level premium residential building with a rooftop pool that overlooks the Brisbane River. The building is 5 years old and is in a prime area, being a 3-minute walk to the Brisbane CBD. The rooftop pool is considered the luxury area for residents, overlooking the CBD area and Brisbane River, but had begun showing signs of wear and tear and was due for renovation.

Unique Elements
The 8-metre-long pool had an infinity edge on two sides that sloped back into the pool. This design meant that the glass mosaic tiles were also installed down the external walls of the pool and into the catchment trough.

The original glass mosaic tiles began losing adhesion to the substrate and started breaking off. Some of these sections were visible above the water level. This was particularly evident from along the inside edge of the angle coping and along the higher outer edge of the pool. This detracted from the aesthetics of the luxury pool environment.

The wall render and bedding screed were also damaged. Portions of the bedding screed had lost adhesion to the concrete substrate and there were hollow and loose sections of render that needed to be removed.

Solution
The team at Peter Johnson Tiling began grinding back the pool to remove the old tile adhesive and any drummy or loose sections of render. Once substrate preparation was completed, repairs to the wall render and bedding screed commenced with render applied prior to waterproofing. This was to prevent the cracking that may occur if the render were applied over a flexible membrane.

Some pool walls were rendered with ARDEX WR 120 FR, a polymer modified render that is fibre-reinforced for extra strength. The pool interior and all wet walls were primed using ARDEX WPM 300 two-component, waster-based epoxy membrane/barrier coating.

The pool was waterproofed with ARDEX WPM 002 membrane. ARDEX WPM 002 includes an advanced acrylic that prevents the membrane from re-emulsifying, is rapid drying and specially designed for use under tiles.

The glass mosaic tiles were fixed using ARDEX X 18 Fibre-reinforced, non-slump tile adhesive and ARDEX E 90 Admixture. This was then grouted with ARDEX EG 15 Epoxy Grout – an easy clean high performance epoxy grout suitable for areas where strict hygiene standards, high chemical and physical resistance are required.

Hitch Property Constructions – Waterproofing Refurbishment

The team at Hitch Property Constructions were able to help out a customer with an urgent project.

By the time the team at Universal Tradesmen received the call, the client was already under pressure on the refurbishment, and for reasons beyond their control. Being a large job, they were desperate to complete this on time. Due to various delays, hold ups in one area started to affect the next, delaying the entire job.

The client was already behind when they began the bathroom refurbishment. They had pulled out the original fittings, fixtures and tiling, and they were ready to waterproof. Some liquid membranes take up to four days to dry after the second coat and they needed to make up for lost time. They gave the team at Universal Tradesman a call, who had the perfect solution.

Four days idle on a bathroom job is not only painful for the builder, but the client too. Liquid membranes can be easily damaged whilst drying, leading to further delays. ARDEX WPM 750 Undertile Butynol sheet membrane was specified as the solution to help overcome these challenges.

The highly skilled waterproofing team at Universal Tradesman had applied ARDEX WPM 750 and completed the bathroom within a two hours and informed the client they would be able to start work again only 60 mins after application. After only one hour after completion of waterproofing, the contractors were back to work tiling: allowing them to shave over 3 full days off the job.

With time saving and reliability of the waterproofing membrane to the entire job costing, the builder stated that by estimate the project worked out to be significantly cheaper. It was completed quicker, and saved costs on labour. Most importantly, the refurbishment was delivered on time, with a high level of customer satisfaction. The builder mentioned how impressed he was with the product, efficiency and knowledge of waterproofing.

If you’re interested in saving days on your next job, ARDEX WPM 750 could be the product that takes your refurbishments to the next level.

The Greek Orthodox Cathedral of Saint Sophia, Sydney

CONSULTANT: BellMont Façade Engineering
REMEDIAL BUILDER: ARA Building Services

The Greek Orthodox Cathedral of Saint Sophia is a heritage listed church located in Paddington, NSW. Having been consecrated in 1927, the church has a storied history as the first Greek Orthodox Cathedral in the Southern Hemisphere and playing an important role in the settlement of newly arrived Greek immigrants in Sydney.

Unique Elements
With the cathedral being 93 years old at the time and being exposed to multiple elements for a lengthy period, there was significant accumulated structural damage. Parts of the building were crumbling, and large cracks had appeared.

The front façade had suffered from reinforcement corrosion with large sections of the concrete mix completely saturated, resulting in corrosion of the steel reinforcement. The left and right corners of the upper level frieze shifted by up to 20mm. And the bedding of the top moulds/corbel had delaminated. The supporting walls which underpinned the entablature were supported off a base slab tied into the structure – forming an intricate gravity based system to support the main wall and entablature.

Saint Sophia was also heritage listed by the NSW Government in 2015, and as such, any work was required to be undertaken in accordance with the Burra Charter. This meant that no alterations to the façade of the building were allowed, other than to reinstate original features.

Solution
BellMont Façade Engineering diagnosed, designed and specified the materials and systems required for the project. As a NSW State Heritage listed item, the design of the solution absorbed extensive time and detailing to maximise the use of existing fabric. All materials that were required for this restoration were approved by BellMont Façade Engineering, ensuring that the Burra Charter was at the forefront of the restoration project. BellMont Façade Engineering designed and supervised installation of the support for the front façade – which was 8 metres above ground level – during the sequential repair of heavily corded reinforcing bars and spalled concrete of the front and rear face of the main entrance wall. This allowed for the front and rear faces of the wall to be repaired separately.

The wall was poured in two separate pours using ARDEX BR 460 FLOW, a high performance, flowable, structural repair micro-concrete. Approximately 9,000 litres of concrete repair was undertaken using the ARDEX BR 460 FLOW – structural grade, flowable repair mortar.

While the elevated wall was being repaired, a propping system was designed to support the entablature – 8 metres above the main entrance portico. The entablature was repaired with ARDEX BR 345, a Microtec® fibre-reinforced structural concrete patching and repair mortar which contains an active corrosion inhibitor.

Approximately 200 lineal metres of ARDEX WPM 1000 WeldTec External Waterproofing Membrane were applied to waterproof the corbels on the building, with the membrane made up of a synthetic rubber with properties which resist ageing from heat, sunlight and ozone. The system was then completed with a liquid membrane coating to match the remainder of the church façade.

800 square metres of ARDEX WPM 310 External Façade and Roof Membrane was applied to the façade of the cathedral. ARDEX WPM 310 is a tough, UV stable and flexible membrane that is designed specifically as a general-purpose membrane for exposed wall and roof waterproofing.

To help prevent further cracking in the structure, 30 lineal metres of Rhino Carbon Fibre Crack Stitching was installed with ARDEX RA 88 PLUS (Multi-Purpose Epoxy Repair Adhesive). Once installed, the Rhino Concrete Crack Lock permanently bonds both sides of the crack together.
