Sodalite Exposed Aggregate – Elanora

Back patio / pool surround at Elanora

We recently completed a patio/pool surround and house surrounds at Elanora. The customer chose to use an exposed aggregate mix, specifically Sodalite from Nucon.

Exposed aggregate – “Sodalite” from Nucon Southport

Sodalite is a white coloured concrete mix with primarily light brown stones. The stone in this mix was smooth and flat. Sodalite has a base cost of $550 + GST per cubic metre (material only). It was only available from the Nucon Southport plant.

In our photos here the concrete looks almost like a pale brown colour. When wet, the mix colour does look almost like a latte or coffee colour. The brown from the stone really contributes to this when wet and most likely will appear this way if a wet look sealer is applied.

When dry, the mix really lightens up and appears closer to a white colour. It can be rather glary on the eyes when in full sun. The customer on this job is going to install a fly over roof above their patio area.

Concreter’s Perspective

From the concreter’s perspective, Sodalite was a fast moving mix. In moderately hot November temperatures (high 20s, low 30s C) the mix was hard and ready to wash within 2 to 3 hours of the truck arriving on site.

The mix is rather “chalky” and doesn’t seem to rapidly bond to materials as much as regular concrete does, so washing tools and surfaces was easier with this mix compared to usual.

The white colouring does create a lot of staining if you wash off into a drain or guttered area and damming the drainage is absolutely necessary.

We barrowed this mix in as the job access was limited and pumping exposed aggregate mix is a risky endeavor, especially when it costs this much. The job was split into two pours to increase access to the work areas, provide wash areas for the 2 house surround areas, to remove the need for a concrete pump and the use of a “pump mix” and to make the pours more manageable overall.

See you on the next one.

Last carpark pour at the childcare centre, Loganholme

Loganholme Childcare Centre

We got the last piece of carpark pour done at an upcoming childcare centre in Loganholme. The project has take a long time due to the crazy wet weather we’ve had this year, as well as the construction industry being in a massive peak workload period and availability of labour is so low.

With only a couple more weeks left to complete this project it feels great to finally see it coming to a finish.

The new childcare centre is set to open in late 2022.
