Face lift for ageing Adelaide beauty

Sunday, 31 July, 2016 | Supplied by: Mapei

An ageing Adelaide leisure centre was given a face lift for its 40th birthday. Contractors used a range of Mapei products to ensure the tiling job was up to scratch. 

The Adelaide Aquatic Centre is a complex of indoor heated swimming pools operated by Adelaide City Council. The centre is located in the northernmost extent of the Adelaide Parklands in North Adelaide. The centre opened on 20 December 1969 and is now over 40 years old.

The centre features a 50 m Olympic-sized swimming pool and a smaller adjacent pool used for aqua aerobics, canoe polo, diving, underwater hockey and water polo. These two pools are surrounded on three sides by raised seating for competition spectators. The wet areas also include an octopus-themed ‘Octopool’ for children’s swimming lessons and recreational use, two leisure pools, two water slides, two spas, a dry sauna and a steam room.  The centre also offers a child-minding area and a health club equipped with cardio machines, pin-loaded weight machines and free weights. There are also shops providing swimming equipment and food, and an outdoor barbecue area.

The upgraded centre.

In 2014, Adelaide City Council together with the South Australian Government commenced refurbishment of the existing pools and areas. The project had an estimated cost of $5 million. 

Tectonic Tiling was awarded the tiling contract and commenced work on the 50 m pool, dive pool and leisure pools. Existing tiles were removed from the two leisure pools, which were then converted into one larger pool area. Contractors repaired the existing concrete walls and floors, as well as repairing and reinstalling the control joints using Mapei’s Kerapoxy (acid-resistant epoxy grout), Mapeband TPE (TPE tape for flexible sealing and waterproofing expansion joints and cracks subject to movement) and Eporip (solvent-free epoxy adhesive for sealing cracks in screeds). 

Pre-tiling work on the main pool.

Mapegrout Rapido — a fast-setting and -drying, shrinkage-compensated, fibre-reinforced mortar for concrete repair — was applied to seal around the penetrations on the pool floors.   

Planicrete SP (latex additive used in the preparation of high-performance screeds and renders), sand and cement were used to obtain a steadfast render which was applied to all areas, followed by two coats of Mapelastic Smart (highly flexible cementitious waterproofing membrane used to protect concrete structure and renders with hairline cracks). Mapetex Sel (non-woven, macro-holed, polypropylene fabric used to reinforce waterproofing membranes) was embedded into the Mapelastic Smart membrane to ensure that the integrity of the pool walls and floor were fully protected prior to the tiling installation.

Tectonic Tiling commenced with the installation of Metz 119 x 244 x 9 mm slip-resistant pool tiles to the flooring areas. Additional tiles were also installed from the Metz pool tile range, including rebated finger grip tiles and grate support tiles to the wet decks, satin finish tiles to the wall areas and step tread tiles to all steps and ladders. Contractors used Mapei’s Kerabond Plus high-performance adhesive mixed with Isolastic (latex additive to improve the adhesion, deformability and impermeability to the substrate once hydration has occurred).

Tiling of the 50 m pool in progress.

The pool tiling was grouted with Ultracolor Plus — specifically chosen for this project due to the grout’s durability in immersed conditions as well as the product’s specific anti-efflorescent properties. Mapesil AC silicone sealant was selected to form a perfectly elastic gasket in the wall/floor expansion joints. Mapesil AC is a sealant suitable for pool environments as it contains properties to resist mould and mildew as well as protection from chemical agents found in pool water.

With over 3500 m2 of tiling, 2500 m2 of waterproofing, 1000 m2 of levelling, 440 m2 of render, 1060 m2 of cement screeds and 2100 lineal metres of silicone joints required to complete all pools, contractors chose to install the final pool tiles using Mapei’s Granirapid (fast-setting adhesive) to accelerate the tiling process, ensuring the project was completed on time.
