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 varity of both commercial and practical reasons. Therefore, although it is a good idea to understand the variety and flexability 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

Planters can be ordered in any of the following standard colours at no additional cost: -

  • Natural Grey – this is a natural raw concrete look made with grey cement without the introduction of any additional colouring.

  • Natural White – 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.

  • Charcoal – 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.

Additional Integrated Colour Options

In addition to the above standard colours, 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 molds 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 substrata.

These are examples of some of the integrated colouring options.

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 pictures below show Satu Bumi installations 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 ambiences. Click on the example images below to expand and click through.

Specialty Paint Finish Options

Today’s acrylic paint technology enables the painting of concrete surfaces to almost any colour or design. 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.

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

  • Rust Verdigris - provides the appearance of rusted copper

GRC Swatches

Satu Bumi swatches for the cityscape range

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

GRC Design Options (Click on any of the images below to expand them for easier viewing)

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, including: -

Standard Planter Feet Options

Planters are typically supplied with feet of around 1 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.

Other GRC Planter Design Options

One of the great features of GRC is that it can be made to virtually any realistic shape or size. Therefore, it can be made to suit the design intent of most commercial landscaping projects.

Alternative Corner Designs For Square Edged Planters

The installation of multiple rectangle planters where corners are involved typically requires the use of L-Joint corners. However, both mitred and L-Shaped corner planter options are also available upon request.

GRC Drainage Options

Appropriate irrigation and drainage are essential elements in the maintenance of healthy plants in any sort of planter. Therefore, Satu Bumi provides the following options for its GRC planters to assist landscapers in this area: -

  • Drainage Risers - these are used to prevent drainage holes on planters from blocking.

  • Raised Drainage Risers - these are used to prevent drainage holes on planters from blocking and for retaining a predefined amount of water within the planters.

  • Pot planter holder inserts - these are primarily for indoor planters and are used to hold small plastic plant holders, within a larger GRC planter, that can be easily watered and replaced.

  • Integrated drip trays - used to hold excess water to avoid patio stains from over watering.

 

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: -

  • Internal planter sealants

    • 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.

  • External planter sealants

    • 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.

  • Table top sealants

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

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

Edge Radius

GRC Planter Edge Finish Example

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.
