Custom GRC Options & Extras

Custom made GRC planter boxes in any size and shape are available from Satu Bumi to suit almost any commercial project

Custom GRC Options & Extras

Satu Bumi has a whole range of custom finishes, textures, designs, sealants and drainage options for its Wholesale and CityScape Ranges of GRC planters that will enable Satu Bumi customers to align the functionality and/or aesthetic appearance of their GRC planters to the requirements of virtually any specific landscaping project or GRC planter marketing initiative.

However, not all the options shown below are available for every Satu Bumi product for a variety of both commercial and practical reasons. Therefore, although it is a good idea to understand the variety and flexibility of what can be done with GRC, it will also be important to discuss your thoughts on option selection with a Satu Bumi representative prior to finalising your requirements.

GRC Finishing Options

  • Standard Colour Options

GRC products can be ordered in any of Satu Bumi’s following standard colours at no additional cost:

  • This is a natural raw concrete look made with grey cement without the introduction of any additional colouring.

  • This is also a natural raw concrete look. However, it is made by replacing the grey cement with white cement and also without the introduction of any additional colouring.

  • This is one of our most popular colour options and is made by applying a specific dosage of an integrated oxide colouring additive to either the natural grey or the natural white GRC mixes during the manufacturing process.

  • Aggregate Finishes

GRC products can be ordered with several standard Satu Bumi aggregate finishes that can be viewed by clicking the image to the right. However, if you require alternative aggregate finishes, contact Satu Bumi to discuss what this means.

  • Additional Integrated Colour Options

In addition to the above standard colours and aggregate finishes, you can also choose any colour from a whole range of integrated colour options off the CCS colour chart. These colours are achieved by adding oxide pigments to the GRC slurry prior to it being added to precast moulds in the production process. The additional cost of these optional integrated colours varies depending on the colours chosen and their pricing can be provided upon request. The advantages of integrated colouring options are that they don’t change the natural concrete appearance of GRC, and superficial damage doesn’t expose a different colour substratum.

The images below are a limited number of examples of a planter with different integrated pigment colours to show the types of colour variations that can be achieved.

Due to the varying cost of the ingredients that go into the pigmented colours, the prices of the different coloured pigments also vary quite considerably. The picture to the right shows an example of a Satu Bumi installation that utilise various GRC planter shapes and sizes in conjunction with a selection of subtly different integrated pigment colours to achieve a soft and appealing ambience.

  • Oxide Surface Finish Options

Oxide surface finishes provide earthy and industrial appearances that cannot be achieved by integrated colouring and painted finishes. These finishes are applied to the GRC surface and Satu Bumi provides the following five standard options that add around 5% to the price of the GRC product being treated:

  • Rust provides the industrial light-coloured appearance of heavily rusted steel.

  • Iron Ore provides the earthy appearance of dark and rich iron ore.

  • Iron Stone provides the earthy appearance of a light-coloured ancient stone.

  • Cast Iron provides the industrial dark-coloured appearance of weathered cast iron.

  • Neo Coffee provides the rich, warm appearance of dark roasted coffee with smooth, polished surfaces and subtle depth.

  • Verdigris provides the appearance of rusted copper.

  • Specialty Paint Finish Options

Today’s acrylic paint technology enables the painting of concrete surfaces to almost any colour. Unless otherwise defined by the customer, Satu Bumi uses Dulux Weathershield paint in Low Sheen, Semi-Gloss or Gloss finish for its specialty painted finishes. The prices of the painted finishes are approximately 9% of the prices of the planters to which the paint is to be applied and the colours can be selected with reference to the official Dulux web site.

Paint is a surface coating that provides a more consistent and solid colouring outcome than what can be achieved using integrated pigments in the concrete mix. However, the use of integrated pigment colouring provides a more traditional coloured concrete appearance than has its own appeal.

Either colouring method will provide a good result. Therefore, the decision on which to use is generally a matter of design intent.

GRC Swatches

It is important to note that screen-based swatches and colour samples are provided for explanatory reasons. Computer screens should not be solely relied on for colour decision making because they can vary based on the screen (make, model and type), screen settings (resolution, contrast and control) and room lighting (incandescent, fluorescent, halogne or natural light). Therefore, where appropriate, Satu Bumi will supply swatch samples to address this issue.

GRC Design Options

With a large product engineering department of designers and mould makers, Satu Bumi is able to provide a wide range of product design options to suite the most discerning architects and designers. The following are examples of some of the design options that can be considered for GRC products.

  • Standard Planter Feet Options

Planters are typically supplied with feet of around 2 cm high. However, the planter feet height can be easily varied upon request. This can be useful in circumstances such as when a planter is going to be installed with pods and pavers, and you want to raise the bottom of the planter to the level of the pavers.

  • Modified Planter Walls

Lowering one or more of a planter’s walls can be useful if you want to abut several planters to provide the appearance of one continuous planter after they are planted. Planter walls can also be raised or lowered to provide barriers and building fascias.

  • Moving & Fixing Options

GRC planters are much lighter than similar sized cast concrete planters because the walls of GRC planters are typically much thinner. However, large GRC planters can still be quite heavy. Therefore, when designing GRC planters, consideration should always be given to how they are going to be installed or moved around after installation.

GRC Drainage Options

Appropriate planter drainage is essential for the maintenance of healthy plants by ensuring that water does not flood the planter.

Satu Bumi provides drainage cells for the bottom of all its GRC planters, at no additional cost, unless otherwise requested by the customer. These drainage cells consist of a crush resistant plastic drainage cell layer to facilitate efficient drainage covered by a layer of Geotech material to stop the contents of the planters from clogging the plastic drainage cell layer.

Depending the circumstances, the Satu Bumi supplied drainage cell may not be what is required. Therefore, Satu Bumi also offers the following options of a drainage riser, a raised drainage riser, and a pot planter holder to assist customers in designing the best drainage strategy for their projects.

GRC Sealing Options

An essential element in the creation of a quality GRC planter, bench, table-top or water feature is the selection of the appropriate sealants. And there are hundreds of different sealants on the market that all have different features, benefits, quality and pricing. Therefore, Satu Bumi has invested considerable time and resources into selecting quality sealant options for the following purposes:

Nevertheless, any of the sealants can be changed at shop drawings stage if they do not suit the customer’s specific requirements.

    • Acrylic membrane sealants - these are used to “tank” the internal walls of planters to prevent leakage.

    • Bitumen sealants - are typically used to “tank” the internal walls of water feature ponds. However, bitumen sealants are also an option if you are looking for a higher level of internal sealant for GRC planters.

    • Penetrative sealants - these are used on the outside walls of planters to protect them against minor marking, moisture absorption and mold growth.

    • Anti graffiti sealants - these are heavy duty topical sealants used for GRC planters or street furniture located in public spaces.

  • These need to be of the highest quality, food safe, scratch resistant and stain resistant.

Edge Radius

Satu Bumi’s GRC planters and street furniture products all have an edge radius to remove sharp edges. An edge radius is both a safety issue and a chip prevention issue.
