Building with Concrete

Concrete feature walls

In this basement we are building an entertainment room and 3 of the 4 walls will be in situ concrete walls to create a concrete feature. The room will comprise a bar, wine cellar and lounge with a window that looks directly in the swimming pool.

Not only will the concrete be a feature but there is also a lot of other features built into the walls including LED back lit floating shelving a wet bar and a wine rack built with metal pins protruding from the wall. 

With the level of detail in the walls its important to set all plumbing, electrical conduits for lighting and power and any penetrations through the walls in the correct spot. You don't get a second chance once the concrete is set.

The steel work, formwork and bracing is complete with the concrete pumped into the walls and vibrated for a smooth finish.

Concrete feature roof

Here is a project I was fortunate to work on for mckimm, which involved building a concrete cantilevered roof structure over an outdoor entertaining area and swimming pool. 

The structure was built like a basement with suspended concrete slab as there is large concrete piling in the ground to hold the steel columns in place which supports the cantilevered concrete structure.

The concrete piling, steel columns and concrete upright walls were installed then the formwork placed for the roof structure. Skylights were placed as voids in the formwork and the lighting conduit plus fixtures installed with the steel reinforcing.

The concrete was vibrated, power trowel finished and sealed with a penetrating sealer for a smooth finish.

Polished concrete floors

Polished concrete floors look great but you need to be aware that concrete continues to shrink over its lifetime and cracks will appear. Set up of expansion joints is important and need to be considered in the design. Any heating and services need to be set up properly before the concrete pour.

The concrete mix can be any colour or type of stones you like, when the concrete is set you can not really tell how its going to look when finished as it looks like plain concrete.

Once the polishing starts thats when you can see the colour and stones. Polishing is done by grinding the floor using a polishing liquid and gradually using a finer grade grinding discs to create a smooth, polished and sealed exposed concrete floor.

Concrete BBQ

This bench was built out of concrete for the BBQ and Sink to be integrated with cabinetry to fit neatly underneath.

The steel starter bars were drilled into the concrete walls and floor with steel bar tied to it to form a self supporting structure, the boxing was then put in place to form a 100mm thick concrete slab. The concrete was placed and vibrated and steel trowel finished on top to form a smooth surface.

The boxing was left in place for 4 weeks while the concrete set fully, Then fitted with the appliances, cabinetry and finished.
