The Project 


When Adrian Rowan, from award-winning Auckland building business 505 Construction wanted to create a beautifully crafted and engaging space for young children to play in, he sought out Allco Waterproofing Solutions to supply crucial waterproofing systems and to input expertise.

Building Campbells Bay Early Learning Centre presented with a raft of challenges to bring the vision of an aesthetically appealing and sensitively positioned childcare centre to life, not the least being how best to shape the historic site creating a myriad of exceptional play areas for children to enjoy while enabling sufficient off-street parking to be accommodated with the least visual impact.


In 2022, this beautiful childcare facility expanded further to include a new underground carpark with additional staffrooms and an extension to the current playground. This extension required tanking to exterior concrete walls and under slab.


Allco Waterproofing Solutions designed, supplied and installed two roofs one extending over the semi-circular Green Roofing system under which cars would be parked and on which children would play in a variety of spaces including sandpits, green spaces and a water-feature.

Dani Foote from Allco oversaw the design and installation of the synthetic JM TPO membrane technology used in the project.  He chose the product given its ability to withstand puncture and its ease of application on dynamic sites like that at Campbells Bay.

“I chose that membrane purely given the nature of how it is installed and the guarantee that it’s construction method using welded laps, would contain and control water above and below it.”

JM TPO is engineered to carry outstanding ozone resistance, superior tear strength and resistance to uplifting.  While it’s strengths are a key feature its also easy to apply given its flexibility through its scrim orientation and its ability to withstand extreme temperatures made it the ideal water-proofing material for the Campbells Bay Early Learning Centre project.

Another key advantage he says is in its extremely cost-efficient construction process, much less labour intensive than standard waterproofing barrier systems.

“It took us just a couple of weeks to install the main green roof and the whole project went extremely well.”

Judged as one of the best at this year’s Property Council of New Zealand Property Industry Awards, the early learning centre is an outstanding example of what can be achieved when a developer makes the right call and engages a company that has the passion and the experience to deliver top-end water-proofing solutions in a way that enhances and adds value the overall appearance of the site.

Daniel Szczepanski, National Sales Manager at Allco describes the company as an industry leader, offering its clients high level consultative services and a range of outstanding products backed by real science and tested to the highest standards.

“We’re dealing with critical elements within a build and the products and experience we offer across tanking, roofing/decking/podium systems and seismic jointing are second to none.”

He says the philosophy underpinning how the company approaches each project it gets involved with is fundamental to its success.

“We believe that great business is business that is conducted in an honest manner.  The products we use are of the highest possible proven quality.  We have a great team on board with a massive collective depth of knowledge and a commitment to deliver the best outcome on each and every project we undertake.”


Allco is proud to have partnered again with 505 Construction and Accurate Waterproofing to waterproof the extension of this iconic community project.

Volclay Swelltite was the chosen membrane for the underground tanking needs, used on pile faced walls and blockwork and internal pile face.

The extension was largely straightforward however there were several interesting details in particular the corner transitions where the internal pile face tanking met the exterior Swelltite wall tanking.
